“…Fifteen studies published between 1982 and 2009 assessed the diagnostic accuracy for various physical examination tests, either in isolation or in combinations, including signs such as swelling or discoloration, as well as symptoms like anatomical snuffbox tenderness, scaphoid tubercle tenderness, clamp sign, resisted pronation or supination, thumb compression-induced pain, and US pain. 5,14,[17][18][19][21][22][23]39,[41][42][43][44][45][46] None were from the United States, and 12 were from Europe. These were all prospective case series, and 11 were ED-based, while two were orthopedic clinic studies and two did not report their clinical settings.…”

ObjectivesScaphoid fractures are the most common carpal fracture, representing 70% of carpal bone fractures. The diagnostic accuracy of physical examination findings and emergency medicine (EM) imaging studies for scaphoid fracture has not been previously described in the EM literature. Plain x‐rays are insufficient to rule out scaphoid fractures in a patient with a suggestive mechanism and radial‐sided tenderness on physical examination. This study was a meta‐analysis of historical features, physical examination findings, and imaging studies for scaphoid fractures not visualized on plain x‐ray in adult emergency department (ED) patients, specifically to address which types of imaging tests should be recommended in patients with persistent concern for acute fracture after ED discharge.MethodsA medical librarian and two emergency physicians (EPs) conducted a medical literature search of PUBMED and EMBASE. The original studies' bibliographies were reviewed for additional references and unpublished manuscripts were located via a hand search of EM research abstracts from national meetings. All abstracts were independently reviewed by the two physicians, and Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS‐2) was used to assess individual study quality. When two or more qualitatively similar studies were identified, meta‐analysis was conducted using Meta‐DiSc software. Primary outcomes were sensitivity, specificity, and likelihood ratios (LRs) for predictors of scaphoid fracture detected on follow‐up in patients with normal ED x‐rays.ResultsA total of 957 unique citations were identified, yielding 75 studies eligible for inclusion in this systematic review. Studies were significantly heterogeneous in design, study population, and criterion standard. The majority of studies were conducted in non‐ED settings (e.g., orthopedic clinics). No studies used accepted diagnostic research publishing guidelines, and the overall QUADAS‐2 methodologic quality was low, indicating an increased risk of bias in the estimates of diagnostic accuracy. The prevalence of scaphoid fractures ranged from 12% to 57% with the point estimate of 25% pretest probability for adult ED patients with concern for scaphoid injuries, nondiagnostic index x‐rays, and scaphoid fractures on later imaging studies. Except for the absence of snuffbox tenderness (LR– = 0.15), physical examination findings lack accuracy to rule in or rule out scaphoid fractures, and no validated clinical decision rules exist. In patients with persistent concern for injury, magnetic resonance imaging (MRI) is superior to bone scan, computed tomography (CT), or ultrasound (US) to both rule in and rule out scaphoid fractures. Both MRI and CT share the added benefit of identifying alternative etiologies for posttraumatic wrist pain.ConclusionsExcept for the absence of snuffbox tenderness, which can significantly reduce the probability of scaphoid fracture, history and physical examination alone are inadequate to rule in or rule out scaphoid fracture. MRI is the most accurate imaging test to diagnose scaphoid fractures in ED patients with no evidence of fracture on initial x‐rays. If MRI is unavailable, CT is adequate to rule in scaphoid fractures, but inadequate for ruling out scaphoid fractures.

“…59 There are a number of other available CDRs to aid the clinician in decision making. 22,52,53,58,[60][61][62]64,66 CDRs not only help in decision making but prevent needless imaging, reduce or eliminate radiation exposure, and keep healthcare costs down. One of the original protocols was the Brand protocol, which was developed in 1982 and specifically designed to curb excessive utilization of radiography, without compromising quality of care or increasing risk for poor outcomes.…”

“…Pain over ASB on pronation followed by ulnar deviation of the affected wrist also gave a specificity of only 52%. 16 Parvizi et al, 10 in a prospective study involving 215 patients with suspected scaphoid fractures, showed that clinical signs of ASB tenderness, the STT and the SCT had low specificity, 19%, 30% and 48%, respectively, when used alone. However, combination of these three clinical tests within the first 24 h increased the specificity to 74%.…”

“…8,9 The clinician is faced with diagnostic and management dilemmas: to identify patients with scaphoid fractures, in the absence of radiographic evidence, without immobilising the majority who do not. 7,10 In 1992, the British Association for Accident and Emergency Medicine (BAEM) issued guidelines for the management of suspected scaphoid fractures. However, there still remains confusion and controversy; consequently, there is a wide variation in the management of suspected scaphoid fractures in hospitals across the UK.…”

INTRODUCTION The objectives of this work were to assess the clinical knowledge of clinicians in the accident and emergency (A&E) departments in England & Wales and evaluate the current trend for the acute management of radiologically normal, but clinically suspected, fractures of the scaphoid.SUBJECTS AND METHODS We conducted a telephone survey on 146 A&E senior house officers (SHOs) in 50 different hospitals. This survey assessed the clinicians' experience, their clinical and radiological diagnostic methods, and their initial treatment of suspected scaphoid fractures. RESULTS The majority (55.8%) of SHOs performed only one clinical test to diagnose suspected scaphoid fractures. Overall, 41% were unable to cite the number of the radiographic views taken and only 10% of departments have direct access to further radiological investigation. There is wide variation in the early treatment of this injury, with the scaphoid cast used most commonly (46%). The majority of SHOs (89%) were unable to describe the features of immobilisation. The mean follow-up period was 10 days, and 53% of cases were followed-up by the senior staff in A&E. Of SHOs, 54% were not aware of any local guidelines for the management of suspected scaphoid fractures in their departments, and 92% were not aware of the existence of the 1992 British Association for Accident and Emergency Medicine (BAEM) guidelines. CONCLUSIONS The clinical knowledge and the management of suspected scaphoid fractures in A&E are unsatisfactory. We, therefore, suggest that the dissemination of up-to-date guidelines could help to educate clinicians to provide better care to the patients.
