Trapezium fractures are very rare and can lead to a significant deficit of hand function if missed. Isolated fractures of the trapezium account for 3–5% of all carpal fractures (1, 2). However, they should not be missed because inadequate treatment of trapezium fractures can lead to permanent impairment based on the substantial forces experienced at the trapeziometacarpal (TMC) joint in pinch and grip (3, 4) . The trapezium forms a double-saddle articulation with the base of the thumb metacarpal allowing motion in two planes—both flexion/extension and abduction/adduction. The volar ―beak‖ ligament from the metacarpal to the trapezium is a key structure in maintaining joint stability and resisting dorsal radial subluxation during a key pinch. The trapezium body articulates with the carpal bones. The trapezial ridge is a volar structure that serves as a radial attachment for the transverse carpal ligament (5) . Trapezium fractures include body and ridge fractures. Fractures of the trapezial ridge can result from a direct blow or from an avulsion injury. Pain in the thenar area following a wrist injury should alert surgeons to the possibility of a scaphoid fracture, but trapezial fractures can occur, albeit more rarely. Recent Publications: 1.
