Contents
The most commonly fractured carpal bone and the second most common fracture of the wrist (after the distal radius).
Results from a fall on the outstretched arm with hyperdorsiflexion of the wrist. This type of injury may cause a clavicle fracture in a child or a Colles fracture in the elderly.
Clinical
History – typical fall with wrist pain. May present after a few days so ask about remote trauma.
Physical – tenderness in the anatomical snuffbox, and also over the scaphoid tubercle on the volar surface.
X-ray
- wrist and scaphoid views are required.
- look for the scaphoid on both the AP and the Lateral
On X-Ray Look for
- Fracture lines(s) – a break in the cortex or trabecular pattern
- Displacement – is there a step between fragments.
- An associated radius fracture.
- Scapholunate dissociation – disruption of the scapholunate ligament with separation of the 2 carpal bones.
