hematogenous osteomyelitis

Most cases of AHO occur in children with no known risk factors.10 Jagodzinski NA, Kanwar R, Graham K, Bache CE. Further diagnostic studies are unnecessary. A more recent article on osteomyelitis is available. Kolinsky DC, Liang SY. Bone infection is called osteomyelitis. Expert Panel on Musculoskeletal Imaging:., Beaman FD, von Herrmann PF, et al. Managing bone and joint infection in children. Individuals are at increased risk of osteomyelitis following trauma, placement of surgical implants or hardware, or if they are Nickerson EK, Sinha R. Vertebral osteomyelitis in adults: an update. Staphylococcus aureus is the most common cause of acute and chronic hematogenous osteomyelitis in adults and children. This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. https://medical-dictionary.thefreedictionary.com/Hematogenous+Osteomyelitis. Background: In previously healthy children, most cases of osteomyelitis are hematogenous. This content is owned by the AAFP. The subacute and chronic forms of osteomyelitis usually occur in adults. Hong DK, Gutierrez K. Osteomyelitis In: Long SS, Prober CG, Fischer M, eds. AHO due to community-associated methicillin-resistant Staphylococcus aureus (MRSA) can cause severe and complicated disease. Infections can reach a bone by traveling through the bloodstream or spreading from nearby tissue. associated with previous surgery, trauma, wounds, . Physical Exam: As above, there are two main presentations, but most commonly children will demonstrate: Localized erythema, swelling, inability to bear weight, Blood Cultures (large studies show blood cultures positive in 48% [Peltola et al. It is more common in. 18 The characteristics of each category can be summarized as follows: (1) Primary hematogenous spread of bacteria mainly afflicts the . The appendicular skeleton is the most common site of osteomyelitis. The lower back is the most common location for osteomyelitis. caused by hematogenous dissemination of a, Posttraumatic: infection following deep injury, Contiguous: spread of infection from adjacent tissue, Most common pathogens causing osteomyelitis. The lower extremity, especially the femur, is involved more often than the upper extremity, where the humerus is most likely to be infected. Risk factors for nonhematogenous osteomyelitis include open fractures that require surgical reduction, implanted orthopedic hardware (such as pins or screws), and puncture wounds. [17], Avoid giving vancomycin with piperacillin-tazobactam; while the combination provides cover against both S. aureus and Pseudomonas, it has a high risk of nephrotoxicity. osteomyelitis (redirected from Hematogenous Osteomyelitis) Also found in: Dictionary, Thesaurus, Encyclopedia . Empiric antibiotic therapy is not usually recommended. Dennis A. Conrad; Acute Hematogenous Osteomyelitis. It is an acute or chronic inflammatory process involving the bone and its structures secondary to infection with pyogenic organisms, including bacteria, fungi, and mycobacteria. With quick, appropriate treatment, only about 5% of all cases of acute osteomyelitis will eventually become chronic osteomyelitis. Over time, the result can be destruction of the bone itself. You have 3 free member-only articles left this month. CVC malfunction or displacement occurred in 17 (23%) patients, catheter-associated bloodstream infection occurred in 8 (11%), fever with negative blood culture results was noted in 8 (11%), and local skin infection at the site of catheter insertion occurred in 4 (5%) patients.35, In another report, children with AHO sent home on IV therapy were 2.1 times more likely to experience catheter-related adverse events compared with children on oral antibiotics only.36 The study suggested that institutional culture and tradition rather than patient characteristics were driving therapeutic choices regarding prolonged IV therapy.36 Oral antibiotic therapy is less expensive and more convenient than IV therapy, and it can be instituted as stepdown treatment when the patient's clinical status has improved (eg, resolution of fever and pain), when bacteremia resolves (if initially positive), when CRP level declines to <3 mg/dL, and when compliance with therapy and follow-up is excellent.10,37,38, A randomized controlled trial conducted in Finland showed that most cases of childhood AHO can be treated with 2-4 days of IV antibiotics followed by 20 or 30 days of oral antibiotics (large doses of clindamycin or a first-generation cephalosporin) in patients who respond quickly and whose CRP values normalize within 10 days.32 In this study, all cases of osteomyelitis were caused by MSSA. Infection may also involve the adjacent intervertebral disc space, which has no direct blood supply in adults. However, if antibiotic therapy fails, debridement (or repeated debridement) and another four- to six-week course of parenteral antibiotic therapy is essential.2628. Pathogen isolation by culture is key for targeted antibiotic therapy. Principles and Practice of Pediatric Infectious Diseases. Bacteria may reach bone matrices via hematogenous spread (primary bacteremia), direct inoculation (traumatic or procedural), or contiguous spread from . Surgical debridement in patients with chronic osteomyelitis can be technically demanding.32 The quality of the debridement is the most critical factor in successful management. cysticcollectionisnotedwith lowT1andhyperintense PDFS signalintensity. Intravenously administered antibiotics, in addition to surgical removal of the prosthesis, is the best treatment. Osteomyelitis. Osteomyelitis, or inflammation of the bone, is usually caused by bacterial infection. MRI also provides greater spatial resolution in delineating the anatomic extension of infection.13. These include: Acute osteomyelitis refers to an infection which develops and peaks over a relatively short period of time. General pathophysiology. There are two main ways that infecting bacteria find their way to bone, resulting in the development of osteomyelitis. AlteredmarrowsignalintensityofthedistalleftfemurwithlowT1andhyperintense T2 and PDFS signals. Inflammation of the bone marrow and adjacent bone. In uncomplicated cases following initial IV treatment, oral regimens have been shown to be as effective as IV regimens. ), piperacillin-tazobactam (Zosyn) or cefepime (Maxipime; given with an aminoglycoside), Clindamycin, 600 mg IV or orally every 6 hours, For gram-negative anaerobes: amoxicillin-clavulanate (Augmentin) or metronidazole (Flagyl), Amoxicillin-clavulanate, 875 mg and 125 mg, respectively, orally every 12 hours. 1 The first category, hematogenous osteomyelitis, is bone infection that has been seeded through the bloodstream. Berendt AR, Peters EJG, Bakker K, et al. Le Saux N, Howard A, Barrowman NJ, Gaboury I, Sampson M, Moher D. Shorter courses of parenteral antibiotic therapy do not appear to influence response rates for children with acute hematogenous osteomyelitis: a systematic review. Oral therapy using fluoroquinolone antibiotics for gram-negative organisms is presently being used in adults with osteomyelitis.23 None of the currently available fluoroquinolones provides optimal antistaphylococcal coverage, an important disadvantage in view of the rising incidence of nosocomially acquired staphylococcal resistance.31 Furthermore, the current quinolones provide essentially no coverage of anaerobic pathogens. Read the, empiric antibiotic therapy for osteomyelitis, pathogen-directed antibiotic therapy for osteomyelitis, Local sinus tract formation, perhaps draining, Indication: initial evaluation as can also exclude, Evaluation of the extent of osteomyelitis. A radiograph can exclude a fracture and malignancy (eg, Ewing sarcoma), while an ultrasound is very sensitive in detecting joint effusions.10 Lytic lesions and periosteal new bone formation may be evident on plain radiographs 2-3 weeks after onset of symptoms.1 Technetium radionuclide (99mTc) bone scintigraphy is a sensitive test and useful to initially locate ill-defined sites of long bone infection or to detect multifocal disease, or it is used in situations when magnetic resonance imaging (MRI) is not feasible due to indwelling devices or braces.5 Radionuclide scans are frequently used as a diagnostic option in many countries but may yield false-negative results in infants.9,10 Computed tomography (CT) scan for diagnosis of bone and joint infection is generally not recommended in high-income countries because CT is less sensitive than MRI and involves exposure to high radiation doses.10, Currently, the imaging modality of choice is MRI, with significantly higher sensitivity (97%-100%) and specificity (92%) compared to radiographs or bone scintigraphy (Figure).4,10 Early changes in osteomyelitis can be detected on MRI within 2-5 days of onset of disease.10 MRI can also detect extraosseous manifestations or complications of AHO (such as pyomyositis, joint effusion, or subperiosteal abscess) and is invaluable for planning the surgical approach if required for management.9,10,21 The limitations of MRI are the cost, availability, long duration of scan time, and need for sedation or anesthesia.10,16. Frequently asymptomatic or only mild symptoms, Urgent consultation with infectious diseases specialist for choice of, Similar to those seen in adults (see Complications), The following are more common in children, Quick, full recovery is common in children who receive appropriate antimicrobial treatment. HHS Vulnerability Disclosure, Help In osteomyelitis of the extremities, plainfilm radiography and bone scintigraphy remain the primary investigative tools8,9 (Table 4).9 Radiographic evidence of bone destruction by osteomyelitis may not appear until approximately two weeks after the onset of infection (Figure 1). From the abscess cavity, the pus spreads between the trabeculae into the medulla, through the cartilage into the joints, or through the haversian canals of the compact bones to the outside. Animal models show that bone infection becomes more likely after trauma. Localized bone pain, erythema and drainage around the affected area are frequently present. Hematogenous osteomyelitis is the most frequent type and primarily affects the metaphysis because the bacteria travel through vascular tunnels and adhere to the bone matrix. In pediatric patients, osteomyelitis is most often a hematogenous infection, However, in small children, always consider, Most common presenting complaints are fever and loss of function (lower extremities affected more commonly than upper extremities), MRI is the most sensitive diagnostic modality. Inclusion in an NLM database does not imply endorsement of, or agreement with, Acute Hematogenous Osteomyelitis in Children.. However, without adequate debridement, chronic osteomyelitis does not respond to most antibiotic regimens, no matter what the duration of therapy is. Grimbly C, Odenbach J, Vandermeer B, Forgie S, Curtis S. Parenteral and oral antibiotic duration for treatment of pediatric osteomyelitis: a systemic review protocol, et al; Pediatric Research in Inpatient Settings Network. Patients usually present within several days to one week after the onset of symptoms. Sign up today to receive the latest news and updates from UpToDate. The epidemiology, microbiology, clinical features, evaluation, and diagnosis of . Erythrocyte sedimentation rate has a limited diagnostic role, although it can be helpful in longitudinal follow-up. One review20 found only five studies involving 154 patients with this bone infection.2125 Delineation of treatment has been difficult for numerous reasons: debridement obscures the impact of antibiotics, clinical situations and pathogens are heterogenous, and years of follow-up are necessary to demonstrate sustained remission. The site is secure. Although the classification systems for osteomyelitis help describe the infection and determine the need for surgery, the categories do not apply to special circumstances (i.e., infections involving prosthetic joints, implanted materials or smaller bones of the body) or special types of infection (e.g., vertebral osteomyelitis). : Manage coexisting medical comorbidities (e.g., Manage patient factors that may have impacted healing prior to. Thereafter, empiric antibiotic therapy based on epidemiology and resistance pattern of the etiologic agent for the patient's specific geographic area must be started. The following recommendations are for the treatment of nonvertebral osteomyelitis. Typical clinical findings include tenderness over the involved bone and decreased range of motion in adjacent joints. Group A streptococcus, Streptococcus pneumoniae, and Kingella kingae are the. In adults, mostly the vertebra is involved. The classic signs of inflammation, including local. Evidence-based content, created and peer-reviewed by physicians. Bethesda, MD 20894, Web Policies Histopathologic and microbiologic examination of bone is the gold standard for diagnosing osteomyelitis. Bury DC, Rogers TS, Dickman MM. Bone biopsy with cultures is the confirmatory test for osteomyelitis and should be performed unless there are characteristic imaging features of osteomyelitis and positive blood cultures. A review of 163 cases, Pediatric bone and joint infections caused by Panton-Valentine leukocidin-positive Staphylococcus aureus. Sequential determinations of CRP are important to monitor response to treatment in AHO patients infected with MSSA and for patients with AHO caused by organisms other than S aureus. Hematogenous osteomyelitis is one of the most common forms of osteomyelitis where the bacteria travel in the bloodstream from other infected site and get lodged into the bone. Treating Osteomyelitis: Antibiotics and Surgery. However, for complicated AHO (eg, multifocal disease, abscesses, venous thrombosis) due to resistant bacteria such as MRSA, prolonged parenteral therapy in conjunction with surgical intervention as appropriate may be necessary. Infective pyomyositis and myositis in children in the era of community-acquired methicillin-resistant Staphylococcus aureus infection, Increasing pyomyositis presentations among children in Queensland, Prolonged intravenous instead of oral antibiotics for acute hematogenous osteomyelitis in children, Polymicrobial (gram-negative, gram-positive, and anaerobic bacteria), Linezolid, daptomycin, trimethoprim-sulfamethoxazole. In most cases, antibiotic therapy should be delayed until culture results are obtained, so as to better tailor treatment. The radiographs may reveal osteolysis, periosteal reaction and sequestra (segments of necrotic bone separated from living bone by granulation tissue).10 A bone abscess found during the subacute or chronic stage of hematogenous osteomyelitis is known as a Brodie's abscess. The change in clinical manifestations and management over the past 2 decades should be reflected in the current imaging approach to the disease. The -lactam antibiotics have satisfactory bone penetration, proven efficacy for osteomyelitis, and an acceptable adverse effect profile when used in higher doses.22,23, Given its excellent oral bioavailability and bone penetration ability, clindamycin is a good choice for long-term oral treatment in osteomyelitis due to susceptible MRSA organisms without in vitro inducible resistance.24 Other alternative agents for MRSA osteomyelitis in selected circumstances include daptomycin and linezolid in patients who do not respond to vancomycin (Table 2).16,25 The role of trimethoprim-sulfamethoxazole for osteomyelitis due to MRSA is anecdotal.25 Other agents (eg, glycolipopeptides, oxazolidinones, and ceftaroline, a novel fifth-generation cephalosporin with activity against MRSA) may be studied in future pediatric clinical trials. After cultures have been obtained, an empiric parenteral antibiotic regimen (nafcillin [Unipen] plus either cefotaxime [Claforan] or ceftriaxone [Rocephin]) is initiated to cover clinically suspected organisms. Niels van der, Diederik P.J. The palpation of bone in the depths of infected pedal ulcers in patients with diabetes mellitus is strongly correlated with the presence of underlying osteomyelitis (sensitivity, 66 percent; specificity, 85 percent; positive predictive value, 89 percent; negative predictive value, 56 percent).7 If bone is palpated, the evaluation may proceed directly to microbiologic and histologic confirmation of osteomyelitis, and thereafter to treatment. The choice of procedure depends on site of infection, presence of hardware, and patient factors (e.g., comorbidities). Epidemiological data refers to the US, unless otherwise specified. aOxacillin, nafcillin, cloxacillin, flucloxacillin, dicloxacillin.

Osteomyelitis: Diagnosis and Treatment. Empiric antibiotic therapy for osteomyelitis is reserved for patients with signs of sepsis or rapidly progressing infections. Clinical practice guidelines by the Infectious Diseases Society of America for the treatment of methicillin-resistant Staphylococcus aureus infections in adults and children. Systemic symptoms and signs such as high fever, tachycardia, and a painful limp are more commonly noted in children with MRSA osteomyelitis than in those with methicillin-sensitive S aureus (MSSA) osteomyelitis, although these findings are not specific only to MRSA.14 In contrast, children aged <4 years with K kingae osteoarticular infection have a more benign presentation and course, with less than 15% febrile during admission and 39% with normal C-reactive protein (CRP) levels.15, The differential diagnosis of AHO includes infection (eg, septic arthritis, cellulitis), trauma, malignancy (eg, osteoid osteoma, acute lymphoblastic leukemia, Ewing sarcoma, osteosarcoma), bone infarction (in children with sickle cell disease or other hemoglobinopathies), metabolic disease (eg, Gaucher disease), vitamin A deficiency, avascular necrosis, or chronic recurrent multifocal osteomyelitis.4,6,10, The diagnosis of AHO is established from a combination of history, physical examination, laboratory tests, imaging, and isolation of the microorganism from the bone, joint, or blood.9,10,16, The nonspecific markers of inflammationCRP and erythrocyte sedimentation rate (ESR)are commonly used in the initial evaluation of AHO.17 CRP has a half-life of 19 hours and can also be followed to ensure the illness is resolving as expected; mean time to normalization of CRP is 7-10 days compared with ESR that is 2-3 weeks or more.10,17 Because CRP decreases more rapidly than ESR, in routine clinical practice, CRP is the preferred test to monitor the course and resolution of illness.17 The role of procalcitonin as a diagnostic aid in bone and joint infections is unclear.10 The white blood cell count may be normal in AHO.13, Detection of the causative organism and knowledge of antibiotic resistance patternsespecially for MRSAare imperative for proper treatment of AHO.10,16 Thus, prior to administration of antibiotics, obtaining blood culture and bone biopsy/joint fluid samples is crucial whenever feasible. In many instances, a bone scan will be positive despite the absence of bone or joint abnormality. In addition to local signs of inflammation and infection, patients have signs of systemic illness, including fever, irritability and lethargy. Diagnosis and Management of Osteomyelitis in Children. Symptoms & causes Diagnosis & treatment Doctors & departments Print Diagnosis Your doctor may feel the area around the affected bone for any tenderness, swelling or warmth. The pelvic bones or clavicles are less likely to be involved than the long bones of the extremities. cefazolin), Anti-staph Penicillin (nafcillin, oxacillin, etc), Clindamycin (if suspecting MRSA and local resistance to clindamycin is low), Historically, AHOM treated with long courses of IV antibiotics, Historically, treatment duration ranged from 4-8 weeks. After completing this article, readers should be able to: The most common type of osteomyelitis, an infection of bone, that occurs in children is acute hematogenous osteomyelitis. C-reactive protein should be measured at baseline and every 2-3 days during early therapy to follow treatment progress. Bacterial growth results in bone destruction and formation of an abscess. Copyright 2023 American Academy of Family Physicians. Microbiology of bone and joint infections in injecting drug abusers. Most -lactam agents (such as ampicillin, ampicillin-sulbactam, and cephalosporin) are effective against K kingae, but the organism is not susceptible to vancomycin or clindamycin.5,9 -lactam antibiotics are also the drugs of choice for osteomyelitis due to GAS or S pneumoniae.1, Culture-negative osteomyelitis is frequently encountered in clinical practice. MRI is an important imaging modality for detecting pyogenic vertebral osteomyelitis.13 This form of osteomyelitis is usually cured without surgery, even though there may be extensive bone involvement. Acute hematogenous osteomyelitis (AHO) is particularly common in children <5 years of age and typically affects the metaphysis because of the rich but slow blood flow of the growing bone.4 The microorganisms enter the bone via the nutrient artery and are lodged in the metaphyseal capillary loops where they begin to proliferate, resulting in the spread of inflammation. A specimen from the culture is then specially treated, and examined under a microscope to try to identify the causative bacteria. [10][13]. Certain conditions increase the risk of developing such an infection, including sickle cell anemia, injury, the presence of a foreign body (such as a bullet or a screw placed to hold together a broken bone), intravenous drug use (such as heroin), diabetes, kidney dialysis, surgical procedures to bony areas, untreated infections of tissue near a bone (for example, extreme cases of untreated sinus infections have led to osteomyelitis of the bones of the skull). This occurs when the inflammation in the spine causes pressure on a nerve root serving one of these other areas. Accessibility Adult patients with osteomyelitis of the spine usually have a longer period of dull, aching pain in the back, and no fever. Osteomyelitis can be either acute or chronic and manifests with signs of local inflammation, including swelling, pain, redness, and warmth. J Pediatr Orthop B. 2.1. Comparative effectiveness of intravenous v oral antibiotics for acute osteomyelitis in children. C-reactive protein is useful in diagnosis and monitoring the course of AHO. and transmitted securely. This type of smoldering infection may also result in areas of dead bone, called sequestra. Relevant specialists for management of comorbidities (e.g., Surgeons (orthopedic or vascular) to determine the need for. For simple, uncomplicated infections, a short course of IV antibiotics followed by oral antibiotics is acceptable if clinical status improves and CRP declines.

The pus destroys the bone and sequesters parts of it in the abscess cavity. The diagnosis of AHO is made using a combination of factors including clinical findings, inflammatory markers, and MRI and obtaining a specimen (bone and blood) for culture when feasible. Smeeing, Roderick M. Houwert, Falco Hietbrink, Geertje A.M. Govaert, Detlef van der. vertebrae are the most common hematogenous site in adults. Diagnosis of osteomyelitis involves several procedures. Interestingly, archeological finds showed animal fossils with evidence of bone infection, making this a relatively old disease. Addition of rifampin is recommended by some experts as part of combination therapy for complicated MRSA infection (such as bloodstream infections and device-related infections), but data on the benefit of rifampin in otherwise healthy children with AHO are lacking.10, Specific Pathogens and Antibiotic Treatment of Acute Osteomyelitis in Children.

Osteomyelitis encompasses a broad spectrum of disease mechanisms with three generally accepted categories: hematogenous (blood borne) spread, contiguous contamination and vascular or neurologic insufficiency associated infection. Empiric regimens for adults should cover: Pathogen-directed antibiotic therapy for osteomyelitis, Potential surgical interventions in osteomyelitis, Refusal to use the limb (pseudoparalysis), ; if a specialist is unavailable the following. A long, sharp needle can be used to obtain a specimen of bone (biopsy), which can then be tested to attempt to identify any bacteria present. Osteomyelitis Definition Osteomyelitis refers to a bone infection, almost always caused by a bacteria. Methods: We reviewed the current literature regarding the epidemiology, microbiology, pathogenesis, clinical presentation, diagnosis, and antimicrobial management of AHO in children. Clindamycin vs. first-generation cephalosporins for acute osteoarticular infections of childhooda prospective quasi-randomized controlled trial. Therefore, biopsy is advocated to determine the etiology of osteomyelitis.14 However, the accuracy of biopsy is often limited by lack of uniform specimen collection and previous antibiotic use. In adults, osteomyelitis is usually a subacute or chronic infection that develops secondary to an open injury to bone and surrounding soft tissue. We list the most important complications. Systemic signs, such as fever and chills, are more common in acute infection. As a library, NLM provides access to scientific literature. Crary SE, Buchannan GR, Drake CE, Journeycake JM.

Depending on the type of chronic osteomyelitis, patients may be treated with parenteral antibiotics for two to six weeks. [10][11], The symptoms of chronic osteomyelitis may be subtle and the diagnosis may only become apparent when late complications occur (e.g., pathological fracture, loosening of implants). (See the image below.) In neonates and children aged <18 months, the metaphyseal vessel loop and epiphyseal vessel are connected via transphyseal vessels traversing across the growth plate. Current Bacterial Causes of Osteomyelitis in Children with Sickle Cell Disease, In developed countries, annual incidence is 8 out of 100,000 children. Diagnosis is supported via laboratory tests, imaging, and/or biopsy. Staphylococcus aureus is implicated in most cases of acute hematogenous osteomyelitis and is responsible for up to 90 percent of cases in otherwise healthy children.17 Staphylococcus epidermidis, S. aureus, Pseudomonas aeruginosa, Serratia marcescens and Escherichia coli are commonly isolated in patients with chronic osteomyelitis. ACR Appropriateness Criteria Suspected Osteomyelitis of the Foot in Patients With DiabetesMellitus. Epidemiologic, bacteriologic, and long-term follow-up data of children with acute hematogenous osteomyelitis and septic arthritis: a ten-year review. Pediatric AHO is a serious infection worldwide. Given the evolution of pathogens, variability in clinical presentations and course ranging from simple to complex disease, and response to treatment, the management of AHO continues to evolve and warrants an individualized, multidisciplinary approach. Before Bone infections may occur at any age. Historically, osteomyelitis has been categorized as acute, subacute or chronic, with the presentation of each type based on the time of disease onset (i.e., occurrence of infection or injury). [22]. X-ray is the recommended initial imaging modality because it is inexpensive and can rule out differential diagnoses; however, it may miss acute osteomyelitis as findings are typically visible only 1014 days after symptom onset. Generally, these bone infections are secondary to an open wound, most often an open injury to bone and surrounding soft tissue. Impact of diagnostic bone biopsies on the management of non-vertebral osteomyelitis: A retrospective cohort study. Blood cultures are positive in up to one half of children with acute osteomyelitis. Walter G, Kemmerer M, Kappler C, Hoffmann R. Treatment algorithms for chronic osteomyelitis. inflammation of bone, localized or generalized, due to an infection, usually by a pyogenic organism. Conrad DA. Dr Conrad has disclosed no financial relationships relevant to this article. In children, acute osteomyelitis usually presents itself as. In culture-negative cases of AHO, the initial choice of empiric antimicrobial therapy should be continued in cases of documented clinical improvement with an associated decrease in CRP. 4 The microorganisms enter the bone via the nutrient artery and are lodged in the metaphyseal capillary loops where they begin to proliferate, resulting in the.

Issues related to the classification, epidemiology, microbiology, clinical manifestations, and diagnosis of osteomyelitis in adults are presented here. Acute leukemia, cellulitis and malignant bone tumors (i.e., Ewing's sarcoma, osteosarcoma) are conditions with similar presentations. The axial skeleton is less likely to be the site of acute hematogenous osteomyelitis. "Shorter Courses of Parenteral Antibiotic Therapy Do Not Appear to Influence Response Rates for Children with Acute, Diagnosis of osteomyelitis requires a set of clinical signs and symptoms, laboratory tests, imaging studies, histological analysis and, finally, the identification of pathogens by means of bone tissue or blood cultures, particularly in cases of, Inflammatory markers, such as ESR and CRP, are often elevated in acute, Short- versus long-term antimicrobial treatment for acute, The present work presents the results of surgical treatment of 178 patients with chronic recurrent, During the analyses of the disease duration it was determined that the chronic, Dictionary, Encyclopedia and Thesaurus - The Free Dictionary, the webmaster's page for free fun content, Vertebral osteomyelitis and septic arthritis associated with Staphylococcus hyicus in a juvenile peregrine falcon (Falco peregrinus), Pediatric acute hematogenous osteomyelitis, Recommendations for the treatment of osteomyelitis, Pathologic morphology of acute experimental osteomyelitis, The surgical treatment of chronic recurrent hematogenous osteomyelitis in children, hematogenic peripheral circulatory failure, Hematogenous Pyogenic Vertebral Osteomyelitis, Spread via the bloodstream; 95% of these types of infections are due to, Spread from adjacent infected soft tissue; about 50% of all such cases are infected by. Prospective evaluation of a shortened regimen of treatment for acute osteomyelitis and septic arthritis in children. Hematogenous osteomyelitis often presents similarly to nonhematogenous disease. For uncomplicated AHO due to MSSA, a short parenteral antibiotic course followed by oral therapy for a minimum total duration of 3-4 weeks is adequate. Pediatr Rev November 2010; 31 (11): 464471. Ultrasonography and computed tomographic (CT) scanning (Figure 3) may be helpful in the evaluation of suspected osteomyelitis.10 An ultrasound examination can detect fluid collections (e.g., an abscess) and surface abnormalities of bone (e.g., periostitis), whereas the CT scan can reveal small areas of osteolysis in cortical bone, small foci of gas and minute foreign bodies. Clinical Practice Guideline by the Pediatric Infectious Diseases Society and the Infectious Diseases Society of America: 2021 Guideline on Diagnosis and Management of Acute Hematogenous Osteomyelitis in Pediatrics. About the only way to have any impact on the development of osteomyelitis involves excellent care of any wounds or injuries. Predis posing conditions include an extraspinal infection site, urinary tract instrumentation, indwelling vascular catheter, hemodialysis, intravenous drug abuse, cancer and diabetes mellitus.34 Vertebral osteomyelitis is usually associated with severe pain and limited ability to function. . Rybak MJ, Lomaestro BM, Rotschafer JC, et al. Acute hematogenous osteomyelitis is best managed with careful evaluation of microbial etiology and susceptibilities and a four- to six-week course of appropriate antibiotic therapy. In children, hematogenous osteomyelitis is an infection that primarily affects the most vascularized regions of the growing skeleton. Infection initially is established in the metaphyseal region of tubular bones, beginning as a metaphysitis following seeding by bacteria. Osteomyelitis is an infection of the bone; it occurs following hematogenous (seeded from a remote source) or exogenous (expansion from nearby tissue) spread of pathogens, most commonly Staphylococcus aureus . This commentary does contain a discussion of an unapproved/investigative use of a commercial product/device. For nuclear imaging, technetium Tc-99m methylene diphosphonate is the radiopharmaceutical agent of choice11 (Figure 2). This article meets the Accreditation Council for Graduate Medical Education and the American Board of Medical Specialties Maintenance of Certification competencies for Patient Care, Medical Knowledge, and Practice-Based Learning and Improvement. The most common form of hematogenous osteomyelitis is vertebral; patients often have back or neck pain and muscle. Results: Arnold SR, Elias D, Buckingham SC, et al..

This infection occurs predominantly in children and is often seeded hematogenously. In: Cherry J, Demmler-Harrison GJ, Kaplan SL, Steinbach WJ, Hotez PJ, eds. Early antibiotic therapy, before extensive destruction of bone, produces the best results in patients with osteomyelitis. Detection of K kingae may be enhanced by direct inoculation of bony exudates or infected joint fluid into blood culture bottles, but the total reported detection rate (on solid media and blood culture vials) is approximately 33%.19, PCR assays may enhance the yield of K kingae.8,19 However, PCR technology is expensive and not readily available. Vertebral osteomyelitis usually involves two adjacent vertebrae with the corresponding intervertebral disk. A positive probe-to-bone test is strongly suggestive of osteomyelitis, especially in diabetic patients with risk factors for osteomyelitis. The specific organism isolated in bacterial osteomyelitis is often associated with the age of the patient or a common clinical scenario (i.e., trauma or recent surgery). Osteomyelitis ( OM) is an infection of bone. Boys are twice as likely to be affected than girls, and children aged <5 years accounted for more than 50% of cases of AHO.5 Early diagnosis and appropriate treatment of osteomyelitis are imperative to avoid serious morbidity and permanent disability.4, The bacterial etiology of osteomyelitis varies with age.5 The pathogen most often associated with AHO is Staphylococcus aureus in 80% of culture-positive cases, followed by group A Streptococcus (GAS).1,5,6 In neonates, S aureus, group B Streptococcus, and gram-negative enteric bacilli are usual pathogens. Belthur MV, Birchansky SB, Verdugo AA, et al.. Pathologic fractures in children with acute Staphylococcus aureus osteomyelitis. Neisseria gonorrhoeae must be considered in neonates and sexually active adolescents.5 In the child with sickle cell anemia, in addition to S aureus, Salmonella spp frequently cause osteoarticular infections.5 In some countries (eg, Spain, France, United Kingdom, Israel, and Switzerland), Kingella kingae is being recognized increasingly as a common etiology of pediatric osteoarticular infections, especially in children <5 years.7 Data on the epidemiology of K kingae infection in the United States are limited. The https:// ensures that you are connecting to the Introduction Bone infection is called osteomyelitis. Recent data suggests that 3 week courses may be appropriate in carefully selected patients (Peltola et al, Song et al). The role of the Panton-Valentine leucocidin toxin in staphylococcal disease: a systematic review and meta-analysis. [18][21], When indicated, obtain a bone biopsy preferably before administering antibiotic therapy to maximize diagnostic yield. Search for other works by this author on: You do not currently have access to this content. Walker EA, Beaman FD, Wessell DE, et al. Osteomyelitis is a bacterial infection of the bone associated with inflammation and bone destruction with an estimated incidence of approximately 8 per 100,000 children each year in high-income countries.1-2 Osteomyelitis can be classified as acute (duration of symptoms <2 weeks), subacute (duration of symptoms 2 weeks to 3 months), and chronic (long-standing infection that evolves over months to years).1 Osteomyelitis can result from direct inoculation from a penetrating trauma or can spread from a contiguous site of infection, but the most common mechanism of infection in children is hematogenous inoculation of the bone during an episode of bacteremia.3, Despite advances in diagnostic and treatment modalities, bone and joint infections are a major cause of morbidity and disease burden worldwide. The authors have no financial or proprietary interest in the subject matter of this article. Leukocytosis and elevations in the erythrocyte sedimentation rate and C-reactive protein level may be noted. Normalbothhipjointswithnoevidenceofsignificantjointeffusionorsepticarthritis. Other pathogenic mechanisms include direct inoculation (usually traumatic, but also surgical) or local invasion from a contiguous infection (eg, cellulitis, sinusitis, periodontal disease). See permissionsforcopyrightquestions and/or permission requests. Maintain a high index of suspicion for osteomyelitis in children; delayed diagnosis and treatment can have detrimental effects on bone development, affecting growth and causing severe long-term impairment. To achieve optimal outcomes, antibiotic treatment should be continued until the CRP concentration has normalized or significantly decreased. For optimal results, antibiotic therapy must be started early, with antimicrobial agents administered parenterally for at least four to six weeks. From Damjanov, 2000. Musculoskeletal Infections intheEmergency Department. Rao N, Ziran BH, Lipsky BA. [1] [1] The long bones of the arms and legs are most commonly involved in children e.g. Hematogenous osteomyelitis Osteomyelitis secondary to contiguous focus of infection No generalized vascular disease Generalized vascular disease Chronic osteomyelitis (necrotic bone) Anatomic. Osteomyelitis in adults often assumes a chronic course and requires prolonged treatment, whereas children typically make a quick and full recovery. The joint is left out while a two- to six-week course of intravenous therapy is given; another joint is then implanted.33 Proposed therapies for prosthetic joint infections include the use of antibiotic-impregnated beads and antibiotic-loaded prostheses. [1] Symptoms may include pain in a specific bone with overlying redness, fever, and weakness. Blood is also cultured in a laboratory, a process which allows any bacteria present to multiply. Very few studies have investigated the treatment of osteomyelitis. After the initial evaluation, staging and establishment of microbial etiology and susceptibilities, treatment includes antimicrobial therapy, debridement with management of resultant dead space and, if necessary, stabilization of bone.18 In most patients with osteomyelitis, early antibiotic therapy produces the best results. Federal government websites often end in .gov or .mil. Zaoutis T, Localio AR, Leckerman K, Saddlemire S, Bertoch D, Keren R. Prolonged intravenous therapy versus early transition to oral antimicrobial therapy for acute osteomyelitis in children, Shortened hospital stay for childhood bone and joint infections: analysis of 265 prospectively collected culture-positive cases in 1983-2005, Peltola H, Pkknen M, Kallio P, Kallio MJ; Osteomyelitis-Septic Arthritis, (OM-SA) Study Group. [2] FOIA Osteomyelitis of the proximal humerus or femur may also be associated with septic arthritis if the involved metaphysis is intracapsular. Two additional trials (conducted in Chile and Australia/United Kingdom) that included predominantly MSSA cases also demonstrated no difference in outcomes when the duration of IV antibiotic therapy was <1 week.33,34 A systematic review from the United Kingdom published in 2013 also concluded that uncomplicated AHO in children >3 months should be treated with 3-4 days of IV antibiotics followed by the transition to oral antibiotics if the child shows a good clinical response.39 Using higher doses of oral -lactam antibiotics is crucial to ensure adequate antibiotics levels in the bloodstream (Table 3).5,37, Oral Antibiotic Dosages for Treating Acute Hematogenous Osteomyelitis in Children5,37, Limited evidence exists on the initial antibiotic choice or the optimal length of parenteral or oral treatment of pediatric AHO.39 The appropriate duration of therapy for AHO is unclear and depends on the infecting pathogen, severity of the disease, concomitant septic joint, and the host.9,40 Historic data indicate high rates of relapse if the duration of antibiotic therapy is <3 weeks.41 However, this study was limited by a retrospective study design, and the reported treatment failures may also be related to other factors such as delay in surgical drainage of subperiosteal or bone abscess in some patients that resulted in chronic disease and subsequent relapse and no surgical intervention in half of the patients diagnosed with chronic osteomyelitis at presentation.41 Data from a clinical trial from Finland published in 2010 support a shorter duration of therapy (20 days) compared to 30 days for uncomplicated AHO, especially if the disease is caused by MSSA.32 A systematic review published in 2013 also recommended a shorter duration of parenteral antibiotic therapy (3-4 days) followed by oral antibiotic therapy to a total duration of 3 weeks in children with uncomplicated AHO (Grade 2 recommendation).39 However, a longer duration of therapy (including prolonged parenteral course) ranging from 4-6 weeks may be warranted for a complicated clinical course (eg, sepsis, venous thrombosis), resistant or virulent microorganism (such as MRSA, Panton-Valentine leukocidin [PVL]positive S aureus), and pelvic or spinal column involvement.10,16,40,42,43 In contrast to MRSA osteomyelitis, multidrug-resistant pneumococcal strains causing AHO and septic arthritis are not associated with an increased risk of complicated disease.44 Data are also lacking on the effectiveness of shorter durations of therapy in selected populations with AHO, such as neonates, immunocompromised or malnourished children, and children with sickle cell disease.39, Studies have shown that appropriate antibiotic therapy alone without surgical intervention may suffice for 90% of cases of AHO.9,13,32 In some cases of complicated AHO due to CA-MRSA, surgical incision and drainage (including multiple procedures) may be indicated.40 The indications for surgical management in AHO include persistent symptoms (fever, local inflammation) not responding to empiric antibiotic therapy, the presence of periosteal or other deep soft tissue abscess (more common with MRSA or strains expressing virulence genes such as PVL), concomitant septic arthritis especially of the hip and shoulder joint, presence of necrotic bone, and formation of a sinus tract.13,40,42, AHO due to MRSA may be associated with more complicated disease compared with AHO caused by MSSA or organisms other than S aureus, including subperiosteal and intraosseous abscesses, deep vein thrombosis at a site adjacent to the infected bone, septic pulmonary emboli, disseminated infection with multiorgan failure, pathologic fractures, longer median hospital stay, increased requirement of surgical intervention to drain deep abscesses, and even chronic sequelae.10,11,40,43,45 Severe disease could be related to an S aureus virulence factor, PVL, a cytotoxin that destroys leucocytes, that has been found to be more prevalent in MRSA.5,10,42,46-48 A delay in the diagnosis and initiation of appropriate treatment can lead to potentially devastating morbidity, including sepsis, chronic infection, disruption of longitudinal bone growth, and angular deformity.13 Pelvic osteomyelitis is often associated with pyomyositis and may be related to infection with CA-MRSA or PVL production.49,50 Close follow-up within 2 weeks following discharge is recommended for patients with AHO to ensure continued clinical improvement.51.

Short duration of initial intravenous treatment in 70 pediatric patients with osteoarticular infections [in Spanish]. Osteomyelitis is an infection of the bones that occurs either via hematogenous spread (most common in children), bacterial spread from local (contiguous) infections (cellulitis or septic arthritis), or traumatic inoculation. This site uses cookies. government site. Fungi and mycobacteria can cause hematogenous osteomyelitis, usually in immunocompromised patients or in areas of endemic infection with histoplasmosis Histoplasmosis Histoplasmosis is a pulmonary and hematogenous disease caused by Histoplasma capsulatum; it is often chronic and usually follows an asymptomatic primary infection.Symptoms are those. Antimicrobials must be administered for a minimum of four weeks (ideally, six weeks) to achieve an acceptable rate of cure (Table 7).16,19 To reduce costs, parenteral antibiotic administration on an outpatient basis or the use of oral antibiotics can be considered. Background: The epidemiology of acute hematogenous osteomyelitis (AHO) in children has changed. Animal models show that bone infection becomes more likely after trauma.1Infection of the vertebrae and intervertebral disks is typically hematogenous. The lower . the contents by NLM or the National Institutes of Health. Osteomyelitis has traditionally been classified into three categories. Polymerase chain reaction assay in tissue sample or joint fluid may enhance the yield of Kingella kingae. Arnold JC, Cannavino CR, Ross MK, et al.. The .gov means its official. Initial hospitalization to assess vascular supply, identify offending microbes, remove dead tissue, drain wounds and assure compliance may be necessary. The disease has increased in frequency, virulence, and degree of soft-tissue involvement. Children with acute osteomyelitis should receive two weeks of initial parenteral antibiotic therapy before they are given an oral agent.28,29, Chronic osteomyelitis in adults is more refractory to therapy and is generally treated with antibiotics and surgical debridement. Systemic Antimicrobial Therapy in Osteomyelitis. Complicated AHO due to MRSA may warrant prolonged therapy with surgical intervention. All content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only. Trends in the epidemiology of osteomyelitis: a population-based study, 1969 to 2009. In stable patients, defer antibiotics until blood cultures and/or bone biopsy have been taken. Patients with chronic osteomyelitis may require antibiotics periodically for the rest of their lives. Non-hematogenous osteomyelitis can, however, occur as a result of contiguous spread of infection from soft tissue or via direct inoculation of infection into the bone from trauma. Outpatient intravenous therapy using long-term intravenous access catheters (i.e., Hickman catheters) decreases the length of hospital stays.2830. Diabetes is a significant contributing factor in osteomyelitis, particularly when patients have concomitant neurologic or vascular abnormalities.33 A wide variety of organisms (e.g., P. aeruginosa, staphylococci, anaerobes) are frequently isolated from these infections. The most common bone involved in acute hematogenous osteomyelitis in children is the femur. Careers, Unable to load your collection due to an error. ACR Appropriateness Criteria Suspected Osteomyelitis, Septic Arthritis, or Soft Tissue Infection (Excluding Spine and Diabetic Foot). Panteli M, Giannoudis PV. Gornitzky AL, Kim AE, ODonnell JM, Swarup I. Osteomyelitis is an infection of the bone; it occurs following hematogenous (seeded from a remote source) or exogenous (expansion from nearby tissue) spread of pathogens, most commonly Staphylococcus aureus. Ruebner R, Keren R, Coffin S, Chu J, Horn D, Zaoutis TE. Bone infections in children are primarily hematogenous in origin, although cases secondary to penetrating. These sinuses traversing the bone persist for a long time and heal slowly. This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any other professional. Prognosis varies depending on how quickly an infection is identified, and what other underlying conditions exist to complicate the infection. (Sensitivity: 43-75%; Specificity: 75-83%), Choice of antibiotic:Empiric therapy in children, First Generation Cephalosporin (e.g. Copyright 2001 by the American Academy of Family Physicians. 1Department of Family Medicine, Mount Sinai Hospital, Chicago, IL, 2Department of Pediatrics, Wake Forest School of Medicine, Winston-Salem, NC. Penicillinase-stable penicillins or first-generation cephalosporins are preferred antibiotics to treat methicillin-sensitive S aureus (MSSA) infection. A six-week course of antibiotic therapy is commonly recommended. Soft tissue procedures have been developed to improve local blood flow and antibiotic delivery. When caused by tuberculosis, osteomyelitis usually affects the thoracic spine (that section of the spine running approximately from the base of the neck down to where the ribs stop). Long bones are more likely to be affected, with the femur being the most commonly affected bone (see below). When the culture results are known, the antibiotic regimen is revised. The diagnosis of osteomyelitis is based primarily on the clinical findings, with data from the initial history, physical examination and laboratory tests serving primarily as benchmarks against which treatment response is measured. Table 1 depicts the various microorganisms causing osteomyelitis in patients with specific risk factors. Treatment generally involves evaluation, staging, determination of microbial etiology and susceptibilities, antimicrobial therapy and, if necessary, debridement, dead-space management and stabilization of bone. The lumbar spine is most commonly affected, followed by the . After completing this article, readers should be able to: The most common type of osteomyelitis, an infection of bone, that occurs in children is acute hematogenous osteomyelitis. From:Peltola H, Pkknen M. N Engl J Med 2014;370:352-360. Acute osteomyelitis develops within two weeks after disease onset, subacute osteomyelitis within one to several months and chronic osteomyelitis after a few months. Acute hematogenous osteomyelitis (AHO) occurs when bacteria enter and proliferate within the cellular and extracellular matrix of bone, generally accompanied by a host inflammatory response. It is usually caused by microorganisms (predominantly bacteria) that enter the bone hematogenously. ; choice of further imaging depends on patient characteristics. Therefore, spread of metaphyseal infection to the epiphysis and joints can occur via transphyseal vessels. Woods et al. Skeletal Distribution of Acute Osteomyelitis in Children. Magnetic resonance imaging (MRI) can be extremely helpful in unclear situations This imaging modality is particularly useful when a patient is suspected of having osteomyelitis, discitis or septic arthritis involving the axial skeleton and pelvis. Over time, the result can be destruction of the bone itself. Some patients note pain in the chest, abdomen, arm, or leg. An abnormal opening in the skin overlaying the area of bone infection (called a sinus tract) may occasionally drain pus. Osteomyelitis may be divided into two major categories based upon the pathogenesis of infection: (1) hematogenous osteomyelitis and (2) nonhematogenous osteomyelitis, which develops adjacent to a contiguous focus of infection or via direct inoculation of infection into the bone [ 1-3 ]. Infection occurs . Hematogenous osteomyelitis involves an infection traveling to the bone from the bloodstream. After the completion of treatment, follow-up should be based on the response to therapy and the overall health of the patient. Another type of scan used to diagnose osteomyelitis is called. Staphylococcus epidermidis, S. aureus, Pseudomonas aeruginosa, Serratia marcescens and Escherichia coli are commonly isolated in patients with chronic osteomyelitis. The specific microorganism(s) isolated from patients with bacterial osteomyelitis is often associated with the age of the patient or the clinical scenario (Tables 515 and 616). The bacteria reach the metaphysis through the nutrient artery. Pkknen M, Kallio MJ, Kallio PE, Peltola H. Sensitivity of erythrocyte sedimentation rate and C-reactive protein in childhood bone and joint infections. Feigin RD, Pickering LK, Anderson D, Keeney RE, Shackleford PG. The incidence of deep musculoskeletal infection from open fractures has been reported to be as high as 23 percent.6 Patient factors, such as altered neutrophil defense, humoral immunity and cell-mediated immunity, can increase the risk of osteomyelitis.
