Abstract

PURPOSE: To present our operative experiences with carpometacarpal (CMC) injuries, excluding thumb.
MATERIALS AND METHODS
Thirty four fracture and dislocations of CMC joint excluding thumb were reviewed retrospectively. Emphases were placed on injury mechanisms, anatomical location, times between diagnosis and surgery, treatment and complications.
RESULTS
The average age of patients was 31.5 years. 19 cases of axial loading by blow as an injury mechanism. The 5th CMC joint was found to be the most frequently involved single joint (18 cases of 34 cases). Dorsal dislocation of CMC joints was present in 12 cases. Comminution of the carpal or metacarpal bone was present in 18 cases. The average time to surgery was 6 days. Twenty-seven cases were operated upon by closed reduction and percutaneous pinning. Seven cases were treated by open reduction and internal fixation. In the last follow up period, a clinically full hand function was restored in 31 cases. Intermittent pain was present in 6 cases in which there was grip weakness in 4 cases and limitation of motion in 3 cases. However, all cases were able to activities of daily living.
CONCLUSION
We obtained good outcomes in CMC joint injuries through the accurate diagnosis and proper operative treatment.
