Case Study
We present a case of simultaneous dorsal perilunate dislocation of both wrists, without a history of fall on outstretched hands. In contrast, it appeared that the mechanism was reverse. His hands were held in radial deviation with wrists in full palmar flexion. The forearms were in neutral position and elbows in mid-flexion. The wrists were suddenly and forcibly pronated. The radiographs of both wrists showed dorsal perilunate dislocation with avulsion fracture of the tip of ulnar styloid process and avulsion fracture of posterior horn of lunate. Radial translation of the carpal bones was also noted. The mechanism is proposed and discussed.
