Although no differences in specificity, accuracy, and PPV were observed, the sensitivity and NPV were significantly higher. As vascular supply to the proximal pole is mainly retrograde, a fracture through the waist places the proximal pole at risk of avascular necrosis. Usually, surgery is needed to clean out the fracture site, to potentially place some form of bone graft to help bone healing, and to stabilize the fracture with pins or screws.Treatment without surgery can include use of a brace, anti-inflammatory medication or a cortisone shot for pain relief. Stress on the scaphoid, due to a forceful motion, may have a fracture as result (mostly due to a fall on an outstretched arm). Those authors chose similar search criteria for their literature reviews and included between 11 Typical mechanism of injury involves axial loading on an outstretched hand where the forces are transferred through the second metacarpal. 10 These views are sensitive in 70 to 90% of cases and miss up to 16% of cases, which is why previous studies have recommended advanced imaging modalities. Scaphoid fractures may be non-displaced (the fragments of the broken bone haven't moved out of position) or displaced (there is some movement of the bone fragments). 30 As MRI, CT scan, and US have become more popular, bone scintigraphy had not been investigated in recent studies. Level of Evidence There is no difference in the rates of non-union between a short-arm cast or a thumb spica; either is perfectly acceptable treatment, but the short-arm cast has less impact on function and is better tolerated. Christiansen T G, Rude C, Lauridsen K K, Christensen O M. Diagnostic value of ultrasound in scaphoid fractures. fractures through the scaphoid bone ) are common, in some instances can be difficult to diagnose, and can result in significant functional impairment. Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider. Memarsadeghi M, Breitenseher M J, Schaefer-Prokop C, Weber M, Aldrian S, Gbler C, Prokop M. Occult scaphoid fractures: comparison of multidetector CT and MR imaginginitial experience. It is the most common carpal bone to break (fracture). A 25 year old man sustains an extension injury of his right wrist while playing football as a goalkeeper, and presents to the emergency department the same day with wrist pain. Does radiography still have a significant diagnostic role in evaluation of acute traumatic wrist injuries? However, no other comparable study could be found investigating the timing and accuracy of imaging. non-weight bearing with negative : x-rays & hip pain Admit Ortho for MRI (if medical cause e.g.syncope, . If you are unable to import citations, please contact The demographic of scaphoid fractures tend to be younger to middle-aged people therefore it is likely they will be active or have jobs or family to attend to. Screw fixation may speed recovery to pre-injury activities; referral for surgery may be indicated, depending on the needs of the patient[9]. 14 Unusual in the pediatrics population and the elderly population where the physis or distal radius, respectively, are more likely to fracture first. This series identifies the more obvious acute fractures but its limitations include missing occult or undisplaced fractures with a false-negative rate of up to 25%. Special scaphoid view X-rays taken with your hand and wrist in a certain position may help to show up a scaphoid fracture. Treatment is usually with a cast worn on your arm up to your elbow for 6-12 weeks. Patients typically present with wrist pain following a fall onto an outstretched hand. https://www.youtube.com/watch?v=ElD_Eh9fE9Q&feature=youtu.be, Treatment of scaphoid fractures and nonunions. For anatomical snuff box tenderness compared to MRI, a statistically significant difference was observed with The carpal indices would only be abnormal in the presence of scaphoid fracture angulation and/or displacement at the fracture site, in the absence of intracarpal ligamentous injury. The scaphoid bone is situated on the thumb side of the hand, it may be injured by a fall on an outstretched hand, by a blow to the wrist or from punching. non-displaced fractures treated with immobilization in cast; internal fixation may be required for displaced waist fractures MRI had the highest sensitivity and specificity for diagnosing scaphoid fractures, which were 94.2 and 97.7%, respectively, followed by CT scan with a sensitivity and specificity at . Beeres F J, Rhemrev S J, den Hollander P et al. Other forms of manual therapy may also be helpful to reduce any residual swelling or pain such as soft tissue work or massage techniques. Enter keywords to find specific resources. The length of immobilization affects negatively the outcomes. Furthermore, a major factor on the sensitivity and specificity of scaphoid fracture can be the experience of the radiologist. What is a scaphoid fracture and what is the usual cause? Diagnosis and Management of Scaphoid Fractures, https://www.ncbi.nlm.nih.gov/books/NBK536907/, Systematic Review of Diagnosis of Clinically Suspected Scaphoid Fractures, Combining the clinical signs improves diagnosis of scaphoid fractures. Brookes-Fazakerley S D, Kumar A J, Oakley J. 68. . Consider these in the same way as a direct FOOSH. 2020 Feb 265(2):96-103. doi: 10.1302/2058-5241.5.190025. Journal of Medical Imaging and Radiation Oncology, 59, 289-291. According to Larribe et al, MRI contrast-(gadolinium) enhanced images showed highest sensitivity (83%) and specificity (100%) as compared to unenhanced sequences with 67 and 67%, respectively, which were statistically significant. This is because of its size and position in the two rows of carpal bones in the hand. Rarely, repeated 'stress' on the scaphoid bone can lead to a fracture. A prospective comparative study. A scaphoid fracture is a break in the scaphoid bone, a kidney bean-shaped bone that sits below the thumb and is part of the wrist joint. Literature Review Fowler C, Sullivan B, Williams L A, McCarthy G, Savage R, Palmer A. 27 This occurs when the fragments of the scaphoid bone heal in an incorrect position - for example, at a slight angle.

Interrater-Reliabilitt bei der Beurteilung von Skaphoidfrakturen in CT-Aufnahmen des Skaphoids in der Ebene des Handgelenkes vs. in der Ebene der langen Achse des Skaphoids. Patient is a UK registered trade mark. 4 They will be able to advise whether and when further investigations are needed. Despite scaphoid fractures being relatively uncommon pro-active treatment of suspected fractures has been seen as a risk management strategy. =0.12); however, it could be used as an alternative tool. This is a procedure where bone tissue is taken from another area of bone in the wrist and inserted into the fracture site. Paediatric Emergency Care, 26(11), 871-872. Unfortunately, we were not able to obtain true and false positive values from six studies and only the specificity and sensitivity were presented. =3), The first scaphoid fracture was described in 1905 by Destot et al following the discovery of radiography. Platon A, Poletti P A, Van Aaken J et al. It is a boat-shaped carpal bone that articulates with the distal radius, trapezium, and capitate. Scaphoid fractures predominantly affect young adults, with a mean age of 29 years. 2, 131-134. Epub 2018 Jan 31. 1996;24:6070. Symptoms can include pain and swelling around the wrist. Immobilisation: The most important thing is immobilisation at the wrist to prevent movement at the radio-carpal joint. The relative increase in time to healing while moving from distal to proximal is secondary to the tenuous blood supply and retrograde arterial flow. =29/42) between 2 to>6 weeks after initial presentation in the clinic which is often described as being the gold standard. Delayed and non-union may be more likely if treatment of a scaphoid fracture is delayed for some reason. Cravener E K, McElroy D G. Fractures of the carpal (navicular) scaphoid. 9 Australian Government Department of Health and Aging (2009) Australasian Triage Scale: Emergency Triage Education Kit. Displaced or non-displaced, Scaphoid fractures are easily the most common fracture of the carpal bones. scaphoid in its entire length. 6 Radiographs are repeated at the 2 week mark if a scaphoid fracture is suspected clinically but the initial X-rays are negative; in the interim, the patient's wrist is immobilized in a plaster or splint. Whilst immobilisation of scaphoid fractures has traditionally been in a thumb spica, there is good evidence to show that immobilisation of the wrist alone in a short-arm cast is just as effective in promoting union and preventing avascular necrosis. Fusetti C, Poletti P A, Pradel P H et al. That is usually the journal article where the information was first stated. Early computed tomography compared with bone scintigraphy in suspected scaphoid fractures. There are different fractures types classified by Herbert and Fisher's system. Full function will eventually be restored if the fracture has been appropriately managed in the initial stages i.e. In young children and the elderly population, scaphoid fractures are rare. The site is secure. The two rows of wrist bones, shown here, are important in understanding a scaphoid fracture. An official website of the United States government. Narrow your search based on theme, field, format, article, type or location. At the two-week visit, the patient should be free of pain, and a follow-up radiograph should be obtained.[2]. The scaphoid bone is stronger than the relatively weak distal radius in these age groups. Rosemont, Ill.: American Academy of Orthopaedic Surgeons, 2001:2524. Both methods have been shown to detect fractures, but the MRI found some significant ligamentous and carpal instabilities in addition to the scaphoid fracture.[8][9][10]. However, he has no pain on longitudinal compression of his thumb. & Chung, C.C. Scaphoid fractures usually occur as a result of a fall on the outstretched hand. Treatment can be conservative (e.g, wrist immobilization ) or in certain cases surgical (e.g., proximal pole fracture ). Forty of the 42 articles mentioned explicitly that the study was performed prospectively, whereas in two studies we assumed that this was the case. Journal of Paediatric Orthopaedics, 34(2), 150-154. Are osteoporosis and distal radius fractures related. What are the symptoms of a scaphoid fracture? If conservative treatment is attempted, a long arm cast with thumb immobilization is appropriate.[2][14]. Clinical Relevance If pain persists and radiographs are still normal, then further imaging in the form of MRI or CT should be undertaken. Acta Orthopaedica, 87(5), 533-537. Literature Review The mean age was 34.1 5.7 years, and the overall incidence of scaphoid fractures missed on X-ray and diagnosed on advanced imaging was 21.8%. If delayed or non-union occurs, various treatments may be suggested, including wearing a cast for a longer period or surgery to help join the bone fragments together. The Medical Protection Society Limited (MPS) is a company limited by guarantee registered in England with company number 00036142 at Level 19, The Shard, 32 London Bridge Street, London, SE1 9SG. Bretlau T, Christensen O M, Edstrm P, Thomsen H S, Lausten G S. Diagnosis of scaphoid fracture and dedicated extremity MRI. Traumatic injury through contact sports and road traffic accidents are also common causes. However, this technique is also operator dependent and is not in widespread use for the detection of scaphoid fractures. This type of break often causes pain and swelling on the thumb side of the wrist. This can often be done via a small cut in your skin. The search term scaphoid fracture was used because it was thought to be a broad inclusive term. fall onto an outstretched hand, Dull pain which is aggravated by hand and wrist movements, Anatomical snuffbox tenderness on examination - highly sensitive 90% indication of scaphoid fracture, but it is nonspecific 40%, Tenderness of the scaphoid tubercle: the physician extends the patients wrist with one hand and applies pressure to the tuberosity at the proximal wrist crease with the opposite hand. 1).Fracture clinic referral is the most common alternative strategy (n = 26/66; 39.4%) with half of these utilising virtual clinics . If the x-ray is normal and an MRI cannot be immediately obtained, then it is generally recommended to immobilize the wrist as discussed below. =0.05). Scaphoid fracture is a common injury encountered in family medicine. If the scaphoid fracture is not healing, you may or may not continue to have symptoms. Therefore, the pre- and postoperative radiographic interscaphoid carpal alignment was measured, using the radiolunate angle, carpal alignment index, scapholunate, and capitolunate angles. Upgrade to Patient Pro Medical Professional? For diagnosis, tenderness on exam at the snuffbox and the volar aspect of the distal tuberosity, as well as scaphoid compression test, in addition to radiographic assessment, are all essential. Borel C, Larbi A, Delclaux S et al. Jain R, Jain N, Sheikh T, et al; Early scaphoid fractures are better diagnosed with ultrasonography than X-rays: A prospective study over 114 patients. Research has shown that the use of MRI or CTs effective in indeterminate a scaphoid fracture. and for 7 US studies. Medgeeks. Timely diagnosis, appropriate immobilization, and referral to surgical opinion when indicated can decrease the likelihood of adverse outcomes. Diagnoses can be differentiated by the location of tenderness, pain with certain maneuvers, and radiographic abnormalities. and transmitted securely. =0.000. (The exception is associated with a trans-scaphoid peri-lunate fracture-dislocation - in this setting, orthopaedics should be contacted to assist with urgent reduction, ideally in theatre). After asking our members what they want in an online platform, we've made it easier to access our membership benefits and created a more personalised user experience. 33 26 Your scaphoid is one of your carpal bones, the collection of bones that makes up your wrist. 18 At this time, the healing process will have started in the bone, which will help the fracture site to show up. Fractures with even small amounts of displacement are prone to nonunion, and operative treatment is recommended[1]. Sometimes surgery is advised. p Therefore, further imaging such as bone scintigraphy, CT, magnetic resonance imaging, and US should be considered in suspected scaphoid fractures without any visible fracture line on plain X-rays. p Shenoy R, Pillai A, Hadidi M. Scaphoid fractures: variation in radiographic views - a survey of current practice in the West of Scotland region. Diagnosis of a scaphoid fracture can sometimes be difficult, as not all show up on X-rays. In total, one study focused on bone scintigraphy, five studies on CT scan, two studies on MRI, and one study on US imaging were published after 2010. showed that the sensitivity of MRI within 24hours after trauma compared to day 10 after initial presentation did not show any difference. Delays in diagnosis and inadequate treatment for acute scaphoid fractures can lead to non-unions and subsequent degenerative wrist arthritis.[4]. It is unclear whether UK hospitals have been able to introduce early scanning and this national survey sought to establish . Mallee W H, Doornberg J N, Ring D et al. Kawamura,K. 26 de Zwart A D, Beeres F J, Kingma L M, Otoide M, Schipper I B, Rhemrev S J. Interobserver variability among radiologists for diagnosis of scaphoid fractures by computed tomography. Some fractures of the scaphoid are not always visible on the initial x-ray and further imaging may be necessary to confirm the presence of a fracture. Ghane M R, Rezaee-Zavareh M S, Emami-Meibodi M K, Dehghani V. How trustworthy are clinical examinations and plain radiographs for diagnosis of scaphoid fractures? Early magnetic resonance imaging compared with bone scintigraphy in suspected scaphoid fractures. from the best health experts in the business. Larribe M, Gay A, Freire V, Bouvier C, Chagnaud C, Souteyrand P. Usefulness of dynamic contrast-enhanced MRI in the evaluation of the viability of acute scaphoid fracture. Because of the difficulty of making this diagnosis and the low healing potential, scaphoid fractures are predisposed to delayed union. ('Avascular' refers to having no blood supply and 'necrosis' means death.) 17 Keywords: Scaphoid healing, CBCT, X-rays, Immobilisation Go to: 1. Many studies consider that with MRI, occult scaphoid fractures could be diagnosed earlier.

A radiological study. For sensitivity and specificity, this was highest for scaphoid tubercle tenderness with 95.23% respectively 74.07% for clinical examination, followed by tenderness of the anatomical snuff box and compression with much lower specificity of 29.62% each. If further imaging cannot be obtained in time, the patient can be treated with a plaster and followed up early with GP or fracture clinic where CT/MRI can be arranged. Initial radiographs obtained in the emergency department with and without labels. Retrieved April 10, 2017 from However, the impact of the MRI magnitude on the resolution of scaphoid fractures stays unclear, as different magnetic field strengths have not been investigated yet. In diagnosing scaphoid fractures, the clinical examination is only specific in 74 to 80% of cases with a positive predictive value of 21%. A scaphoid non-union fracture refers to a wrist fracture that is failing to heal. These only included standard (a) posteroanterior and (b) lateral views of the wrist. Treatment is usually with a cast worn on your arm up to your elbow for 6-12 weeks. How common are they and how do they occur? Kumar et al The mean age was 34.15.7 years, and the overall incidence of scaphoid fractures missed on X-ray and diagnosed on advanced imaging was 21.8%. The word "scaphoid" comes from the Greek term for "boat." The scaphoid bone resembles a boat with its relatively long, curved shape. M.S., & Pollock. Of the 42 articles, 11 studies performed comparisons between different imaging modalities. Senall J A, Failla J M, Bouffard J A, van Holsbeeck M. Ultrasound for the early diagnosis of clinically suspected scaphoid fracture. These included a follow-up scaphoid plain radiography in 29 cases ( In non-union, the bony fragments are still completely separated. Two hundred sixteen abstracts that included the diagnostics of the scaphoid were reviewed. =0.002), CT ( p [1][2], A delay in diagnosis of scaphoid fractures can lead to a variety of adverse outcomes that include nonunion (no consolidation), delayed union, decreased grip strength, and range of motion, along with osteoarthritis of the radiocarpal joint. Three of the standard scaphoid series are presented including (a) posteroanterior, (b) pronated oblique, and (c) Ziter views. doi:10.1016/j.jhsa.2008.04.026. 94B(8), 1077-1085. It connects two rows of these bones - the proximal row (closer to the forearm) and the distal row (closer to the hand). For our review, we only included the CT scaphoid sequences. A statistical analysis. =0.01) as well as for the carpal alignment index. Unfortunately, delaying treatment can cause problems. Kitsis C, Taylor M, Chandey J, Smith R, Latham J, Turner S, Wade P. Imaging the problem scaphoid. The fracture is . Follow up is very important and parents should be advised that they attend appointment as arranged, because undertreated scaphoid fractures can have significant long-term implications. The role of bedside ultrasonography for occult scaphoid fractures in the emergency department. If this is the case, a CT scan or MRI scan may be suggested to look for the fracture. This systematic review and meta-analysis show that MRI has the highest sensitivity and specificity for detecting scaphoid fractures. Complications include nonunion and avascular necrosis . Indications for operative management include: Surgical fixation involves the insertion of a single or multiple screws and can be done percutaneously or via anopen procedure. By orientation: transverse, vertical or oblique Egton Medical Information Systems Limited has used all reasonable care in compiling the information but make no warranty as to its accuracy. Evenski, A.J., Adamczyk, M.J., Steiner, R.P., Morscher, M.A., & Riley, P.M. (2009). Blood supply to the scaphoid bone is predominantly from branches of the radial artery (dorsal carpal branch). Carpenter C R, Pines J M, Schuur J D, Muir M, Calfee R P, Raja A S. Adult scaphoid fracture. However, avascular necrosis does not occur with all fractures around the waist of the scaphoid. This underpins the basis of best practice guidelines (3). Clementson, M., Bjrkman, A., & Thomsen, N. (2020). For therapeutic decision making, the scaphoid is divided into three anatomic sections: proximal, medial, and distal (see image). Mallee WH, Walenkamp MMJ, Mulders MAM, et al; Detecting scaphoid fractures in wrist injury: a clinical decision rule. There will be pain around the wrist area after the injury. The scaphoid bone is the most commonly fractured carpal bone. Occult scaphoid fractures are defined as wrist pain and scaphoid tenderness with no visible fracture line on X-rays. Because of this absence, the predictive valuespositive as well as negative (PPV and NPV)were not accessible in four studies. [5], As a basic rule, in a patient with a clinically suspected scaphoid fracture but negative initial radiographs, it is reasonable to apply a short arm thumb spica and re-evaluate the patient in two weeks. 2nd ed. J Wrist Surg. MRI has been shown to be superior to conventional radiography, in its ability to detect the scaphoid fracture and a negative MRI can reduce societal costs of unnecessary immobilization, since a normal MRI essentially rules out a scaphoid fracture. 67, In addition, the standard website used for CT radiographs evaluation may have a major impact on the accuracy of scaphoid fracture diagnosis. Or for more specific content, you can always try our refined filters. A scaphoid fracture is usually diagnosed by an x-ray of the wrist. Evidence suggests that MRI in XR negative scaphoid injuries provides benefit in diagnosis and patient outcomes (1,2). During the extension and radial deviation of the wrist, the movement is limited by the scaphoid conflicting with the radius. tenderness on axial loading of the thumb caused by holding the thumb and applying force towards the 1st metacarpal. The pain, which often is mild, is aggravated by pinching and gripping. Often if a scaphoid fracture is suspected and not seen on plain film, a follow-up will be performed in 7-10 days 1. 72. Disclaimer: This article is for information only and should not be used for the diagnosis or treatment of medical conditions. 23 2 Because of the inconsistency in data and steadily improving imaging quality, an updated systematic review and meta-analysis was performed. p Stordahl A, Schjth A, Woxholt G, Fjermeros H. Bone scanning of fractures of the scaphoid. Cochrane Database Syst Rev. It is not clear which imaging modality is the best. 1 Scaphoid fractures - Don't miss this!. Clinical examination and plain X-rays are commonly used to diagnose the fracture, but this approach may miss up to 16% of fractures in the absence of clear-cut lucent lines on plain radiographs. Registered number: 10004395 Registered office: Fulford Grange, Micklefield Lane, Rawdon, Leeds, LS19 6BA. These two index tests were applied in CT and compared with US and MRI. Emergency Medical Journal, 27(4), 266-269. As the fracture line moves proximally, there is more risk of displacement and nonunion; therefore, it would be appropriate to refer these patients for orthopedic consultation. Diagnostic accuracy of imaging modalities for suspected scaphoid fractures. 31 The sensitivity for CT wrist was 33% with a specificity of 89%, as compared to 67 and 95% for CT scaphoid. So, there is a risk that if you have a fracture in this area, it can sometimes stop the blood supply to part of the scaphoid bone, leaving part of the bone without a blood supply. [3][2], Scaphoid fractures are common, but present unique challenges because of the particular geometry of the fractures and the tenuous vascular pattern of the scaphoid. Acute scaphoid fractures: Management under consideration of the new S3-level guideline, Return to sport following scaphoid fractures: A systematic review and meta-analysis, http:///index.php?title=Scaphoid_Fracture&oldid=294623. Although the sensitivity and specificity of CT are lower than that of MRI, it is the only modality which is quick and reliably available in the emergency department. Avascular necrosis of the scaphoid in children treated by splint immobilisation. A small screw or a special pin is inserted into the scaphoid bone to hold the bone fragments together in the correct position. In the proximal row are the scaphoid, lunate, triquetrum and pisiform bones. Cruickshank J, Meakin A, Breadmore R, Mitchell D, Pincus S, Hughes T, Bently B, Harris M, Vo A. Acute scaphoid fractures: guidelines for diagnosis and treatment. Most people with a scaphoid fracture (which is the same as a broken wrist) will have pain and/or swelling along the thumb side of the wrist within days following a fall. or finally, misinterpretation of bone bruise or vascular channels. Scaphoid fractures are not always visible on X-ray as discussed above. Fracture fragments are inherently unstable and prone to displacement and require motionless contact to achieve union. 2020 Apr140(4):575-581. doi: 10.1007/s00402-020-03383-w. Epub 2020 Mar 3. So, if a scaphoid fracture is suspected but not confirmed on an initial X-ray, you will usually be treated as if you have a scaphoid fracture (see below). This means that the scaphoid will not be able to heal properly and part of the scaphoid bone 'dies', collapses and breaks up. It is rare for very young children ( About 3 months ago after doing heavy bench presses, I had pain near the upper right pectoral muscle that extended to my Assess your symptoms online with our free symptom checker. Regarding CT, it has been shown that general wrist CT and CT scaphoid sequences (in the corresponding planes) yielded different sensitivity and specificity, favoring the CT sequence formatting specifically for the scaphoid. This may vary between the tenderness of the scaphoid tubercle with a sensitivity of 95.23% and specificity of 74.07%, tenderness of the anatomical snuffbox (sensitivity=85.71% and specificity 29.62%), or a direct compression test (sensitivity=42.85% and specificity=29.62%). Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). p If this happens, it may affect the movement of the wrist and lead to pain and problems gripping and holding objects. ROM exercises in the initial stages after immobilization should focus on active-assisted ROM as the hand and wrist will be stiff.[6]. Once a full or functional AROM has been restored it is essential to undergo strengthening exercises of the wrist and hand. 12 25 For CT scan, there were 14 publications. Clinically Relevant Anatomy The scaphoid is one of the 8 carpal bones of the wrist. Pain management withthe assistanceof pharmacists shouldbe considered. Accessibility The latter is preferable for non-unions and those fractures that exhibit gross displacement with the former for acute, minimally displaced fractures[5]. Herneth A M, Siegmeth A, Bader T R, Ba-Ssalamah A, Lechner G, Metz V M, Grabenwoeger F. Scaphoid fractures: evaluation with high-spatial-resolution US initial results. MPS is not an insurance company. Although US is not the most accurate, it still has the advantage that it is easily accessible, cheap, and fast. A randomized prospective trial J Bone Joint Surg Br 73(5):828-32. Axial loading of the wrist with it in forced hyperextension and radial deviation can cause the fracture as the scaphoid impacts on the dorsal rim of the radius. 7. p Indications. eCollection 2020 Feb. 9 High frequency USG has also been . Memarsadeghi M, Breitenseher M J, Schaefer-Prokop C, Weber M, Aldrian S, Gbler C, Prokop M. Occult scaphoid fractures: comparison of multidetector CT and MR imaginginitial experience. Scaphoid fractures are almost always caused by catching yourself with outstretched arms after a fall. Mc Dermid, Patient Rating of Wrist Pain and Disability: A Reliable and Valid Measurement Tool, 1998. 10 20 Careers, Unable to load your collection due to an error. Overall, 102 patients had a clinical scaphoid injury but negative X-rays. They happen when you break your scaphoid bone a small bone near the base of your thumb. Get Top Tips Tuesday and The Latest Physiopedia updates, The content on or accessible through Physiopedia is for informational purposes only. [6] As mentioned before, the blood supply of the scaphoid is tenuous. Ultrasound identified correctly 7 of 9 cases that were eventually positive for scaphoid fracture on plain x-ray. It can sometimes be quite difficult to diagnose a scaphoid fracture. In addition, the majority of studies on this topic were conducted prior to 2010, which is at risk of being outdated considering the rapid advance of radiographic technology. All except three studies observed a sensitivity of<100% for MRI (80 or 83%), which was explained by only a short MRI scanning time of 7minutes, Should you need to contact us, our phone numbers are always visible. MPS and Medical Protection are registered trademarks. Scaphoid fractures almost never require acute reduction in ED. We do not capture any email address. Examination reveals tenderness over the radial side of the wrist, including within the anatomical snuffbox, as well as tenderness over the tubercle of the scaphoid. Tiel-van Buul M M, Roolker W, Verbeeten B W, Broekhuizen A H. Magnetic resonance imaging versus bone scintigraphy in suspected scaphoid fracture. There is currently some debate as to whether there is benefit of doing further investigations such as a CT or MRI scan earlier if a scaphoid fracture is suspected but has not shown up on the initial X-ray. . Some also argue that it allows normal movement of your wrist to return more quickly than if you had just been treated with a cast. In two studies, the two index tests were used, which are thought to be positive if the findings of two different modalities including clinical findings correspond with each other, either signs of fracture (positive) or absence of a fracture line (negative). Confirmed Scaphoid Fracture on X-Ray or CT, Clinically Suspected Scaphoid Fracture not shown on plain X-Ray. The scaphoid bone is the most commonly broken (fractured) carpal bone. 9 axially/longitudinally compressing a patients thumb along the line of the first metacarpal) was shown to be helpful in identifying a scaphoid fracture, but in another study, Pain in the snuffbox with pronation of the wrist followed by ulnar deviation (52% percent positive predictive value, 100% percent negative predictive value), An intrascaphoid angle greater than 35 degrees (humpback deformity), A radiolunate angle of more than 15 degrees, Non displaced waist fractures in individuals that need to return quickly to work/sport. European Journal of Trauma and Emergency Surgery. However, about 2 in every 10 scaphoid fractures may not be seen on X-ray at first. Munk B, Bolvig L, Krner K, Christiansen T, Borris L, Boe S. Ultrasound for diagnosis of scaphoid fractures. As such, additional imaging may be required. 13 When refering to evidence in academic writing, you should always try to reference the primary (original) source. It is a boat-shaped carpal bone that articulates with the distal radius, trapezium, and capitate. For evaluation DICOM viewer showed superior performance and besides direct fracture signspresence of a radiolucent fracture lineindirect signs should be used. If x-ray is normal and clinical suspicion is high, then CT or MRI may be obtained to further rule out fracture depending on clinical situation. Scaphoid Fracture: Paediatric Emergency Care. 6. Scaphoid waist fractures with moderate displacement (0.5-1.5 mm) can be treated conservatively, require prolonged cast immobilization for eight to ten weeks. 2018 Aug21(4):206-210. doi: 10.1016/j.cjtee.2017.09.004. This can occur, for example, in gymnasts and shot putters. All the benefits of membership of MPS are discretionary as set out in the Memorandum and Articles of Association. Osteoarthritis can develop some time after a scaphoid fracture in some people. Patient does not provide medical advice, diagnosis or treatment. 7, 8 Some consider MRI as the gold standard investigation for clinically suspected scaphoid fracture, and it allows diagnosis of occult bony and soft-tissue injuries.
