Volar Capitate Dislocation: A Case Report

Abstract

We present a rare injury involving a volar dislocation of the distal capitate with secondary median nerve compression. The injury was not recognized on the initial radiographs resulting in a delayed diagnosis and treatment. A satisfactory outcome was achieved following open reduction and internal fixation via dorsal and palmar approaches. This case illustrates the importance of careful review of radiographs for evidence of intercarpal injuries.

Isolated Open Dislocation of the Capitate

“…Delays in recognition of capitate dislocations have been shown in the literature, especially where only a portion of the capitate is dislocated, such as at the carpometacarpal joint 8 . Computed tomography scanning should be used in cases where routine x-rays are negative, but clinical suspicion is high for a dislocation, especially in the setting of median nerve compression symptoms.…”
