무지를 제외한 수근중수간 관절의 골절 및 탈구

Abstract

Purpose : We present our operative experiences with uncommon carpometacarpal (CMC) injuries, excluding the thumb.

Materials and Methods : Twenty four fractures and dislocations of the CMC joint excluding thumb, which were followed up for an average of 18 months were reviewed retrospectively. Emphases were placed on associated injuries, radiographic findings, treatment and complications.

Results : The average age of patients was 35 years with 14 cases of indirect trauma as an injury mechanism. Eighteen of 24 cases involved the 4-5th CMC joint, one case involved the 2-3rd joint and one case involved the 3-4th joint. In addition, there were 4 cases that involved all of the CMC joints. Seven cases were operated upon by closed reduction and percutaneous pinning, 16 cases were treated by open reduction and internal fixation, and 1 case received fusion for neglected injury. Eighteen cases had satisfactory results, 2 cases had residual pain, 2 cases showed a limitation of motion and 2 cases had grip weakness.

Conclusion : Proper diagnosis and treatment of CMC joint injuries can reduce complications and avoid additional procedures.
