Scaphoid fractures (i.e. fractures through the scaphoid bone) are common, in some instances can be difficult to diagnose, and can result in significant functional impairment. Although they occur essentially at any age, adolescents and young adults are most commonly affected 1.

Classically there can be a pain in anatomical snuffbox which is thought to have a sensitivity of ~90% and a specificity of ~40% 4. The usual mechanism is falling on an outstretched hand with resultant hyperextension of the wrist or purely compressive force 7.

Occasionally stress fractures are also encountered although these are less common, and only usually seen in athletes (e.g. shot putters or gymnasts) 8. ClassificationPlain radiograph A dedicated plain radiographic series investigating the scaphoid exists, consisting of four projections of the scaphoid bone.

Associated scapholunate ligament disruption (Terry Thomas sign) which can be accentuated with a clenched fist view This can be on account of the rest of the wrist undergoing demineralization due to immobilization, whereas the proximal portion being bereft of blood supply retains its calcium.

Fracture location (distal pole, waist, proximal pole) involvement of articular surfaces displacement or step humpback deformity due to angulation between proximal and distal parts Importantly if no fracture is seen it is essential to recommend repeat x -rays (including dedicated scaphoid views) in 7-10 days 1.

MRI is the most sensitive modality for trabecular fractures, and this can detect completely displaced fractures, especially in the first 24 hours following injury 9,13. Nuclear medicine Although bone scans are more sensitive than plain radiograph, they are usually reserved for patients with ongoing pain despite normal serial plain films 8, 13.

In certain circumstances further views are helpful so that the 8 overlapping bones are more easily seen. The wrist comprises the scaphoid, late, triquetral, misinform, trapezium, trapezoid, capitate and ham ate bones.

Like many other carpal injuries this fracture can have significant long term clinical consequences if not identified. There are numerous joints of the wrist, named according to their relative bones.
