In the event of a fall onto an outstretched hand (FOOSH), this is the area through which the brunt of the force will focus. Pain with the scaphoid compression test (i.e., axially/longitudinally compressing a patients thumb along the line of the first metacarpal) also was shown, in a retrospective analysis,6 to be helpful in identifying a scaphoid fracture, but in another study,7 this technique had a poor predictive value for identifying scaphoid fractures. In other cases, a larger incision is needed to ensure that the fragments of the scaphoid line up properly. Motor function is typically intact. All material on this website is protected by copyright.

The differential diagnosis for suspected scaphoid injuries includes fractures of other metacarpal bones or the distal radius, scapholunate dissociation, arthritis, tenosynovitis, or strains (Table 1). This is understandable as the scaphoid is a small, oddly shaped bone whose purpose is to facilitate mobility rather than confer stability to the wrist joint[citation needed].

Continued or new symptoms should be evaluated using neuroimaging and electrodiagnostics because a more severe nerve injury is likely. In the anatomical snuffbox, the radial artery is closely related (<2mm) with the superficial branch of radial nerve near the styloid process of radius in 48%, while in 24% the radial artery is closely related to the lateral cutaneous nerve of forearm. The extensor tendons passing into the thumb forms the triangular depression called "anatomical snuffbox" on the posterolateral side of the wrist and metacarpal I. MRI or bone scintigraphy may be used initially if the patient desires an alternative approach. Paresthesias precede clinical examination findings of sensory loss. This is when the tendons of the extensor pollicis brevis and abductor pollicis longus get inflamed (usually due to overuse, particularly gripping/grasping).
