Two to 5% of scaphoid fractures are missed on initial presentation. The failure of early recognition and treatment are considered to contribute to delayed union and non-union. Despite advances in diagnostic imaging, a dogmatic approach has persisted in the management of patients with clinical suspicion but no radiographic evidence of scaphoid fracture. A critical analysis of the current treatment protocol of indiscriminate cast immobilization and serial clinical and radiographic follow-up is presented. ⋯ The incidence of radiologically inapparent fractures of the scaphoid is low. The use of a tender anatomical snuff box as the only clinical sign in the diagnosis of scaphoid injury is unsatisfactory. Other injuries around the wrist must be carefully excluded. There is insufficient evidence to support immobilizing all patients with clinical scaphoid fractures. For suspected fractures with no radiological evidence, symptomatic treatment is probably sufficient. Most occult fractures are visible at 2 weeks. Both magnetic resonance imaging and bone scintigraphy are accurate and cost effective and should be performed earlier rather than later.

Clinical Trial
Clinical diagnosis of fractures in a paediatric population.
Diagnosing fractures in the paediatric population is a problematical process for which there are currently no accepted clinical criteria. We studied the physical signs sought by accident and emergency staff in 126 children with suspected fractures. We found a significant correlation between 'point tenderness' and fracture, as demonstrated by plain radiograph. 'Swelling' and 'redness' approached significance. These results correlate well with previous work in this area, but further research using a larger sample is required as confirmation.
