Posterior Perspective of the Fractured Distal Radius

Description

Presented is the male right radius in posterior aspect, with the distal metaphysis and epiphysis expanded toward the wrist and the shaft tapering proximally toward the radial head. A transverse fracture crosses the distal radius near Lister’s tubercle, with a small diastasis at the break highlighted by focal red coloration. From this dorsal perspective, the posterior surface contours that guide the extensor tendons are emphasized, with the tubercle positioned centrally on the distal radius and the ulnar notch lying medially toward the distal radioulnar joint. Dorsal distal radius fractures matter because this is where orthopedic fixation and tendon complications intersect. Lister’s tubercle acts as a pulley for the extensor pollicis longus (EPL), and post-fracture callus, dorsal prominence, or dorsal plate placement can precipitate EPL attrition and delayed rupture, sometimes weeks after injury. This angle also supports teaching of dorsal comminution patterns and why malreduction can alter distal radioulnar joint congruence and forearm rotation. Use this asset in upper limb anatomy modules when introducing posterior bony landmarks of the antebrachium and wrist, and in orthopedics teaching materials covering Colles-type distal radius fractures, dorsal approaches, and hardware positioning relative to extensor compartments. It also fits clinical hand surgery publications discussing tendon rupture risk around Lister’s tubercle and postoperative surveillance.
