Surgical Treatment of an Isolated, Pure Palmar Carpo-Metacarpal Dislocation of the Fourth Metacarpal: A Case Report

Isolated carpo-metacarpal dislocations are very rare injuries, with palmar cases being particularly exceptional. Few cases of isolated palmar carpo-metacarpal dislocations have been documented. These injuries are generally unstable and require urgent intervention, typically involving closed or open reduction, followed by internal fixation and plaster cast immobilization. We present the case of an isolated dislocation of the fourth left carpo-metacarpal joint in a young woman. Treatment involved cross pinning, with postoperative immobilization using an intrinsic plus splint for three weeks, followed by rehabilitation after removal of the cast. The functional outcome was satisfactory.
