Abstract
BACKGROUND
Isolated capitate fractures are rare carpal fractures. Following high-energy injuries, capitate fractures are usually associated with other carpal fractures or ligament injuries. The management of capitate fractures depends on the fracture pattern. Here, we report an unusual capitate fracture with a dorsal shearing pattern and concomitant carpometacarpal dislocation, with a 6-year follow-up. To the best of our knowledge, this fracture pattern and surgical management have not been previously reported.
CASE SUMMARY
A 28-year-old man presented with left-hand volar tenderness and decreased grip strength that persisted for one month after a traffic accident. Radiography showed a distal capitate fracture with carpometacarpal joint incongruence. Computed tomography (CT) revealed a distal capitate fracture with carpometacarpal joint dislocation. The distal fragment was rotated by 90° in the sagittal plane, and an oblique shearing fracture pattern was noted. Open reduction and internal fixation (ORIF) with a locking plate were performed using the dorsal approach. The imaging studies performed 3 mo and 6 years following surgery revealed a healed fracture, and the Disabilities of the Arm, Shoulder, and Hand and visual analog scale scores were significantly improved.
CONCLUSION
CT can detect capitate fractures with dorsal shearing pattern and concomitant carpometacarpal dislocation. ORIF using a locking plate are possible.
