Abstract
Purpose
We present the results of operation about 12 patients diagnosed as scapholunate dissociation with journal review Material and Method: This was a retrospective study of 12 cases operated for scapholunate dissociation between May of 1992 and April of 2005. Ten cases had dynamic carpal instability and 3 cases had static carpal instability. The follow-up period averaged 32 months (range, 6-68 months). All patients had surgical treatment by either direct repair in 4 cases or transosseous suture in 12 cases through open dorsal approach. Additionally, modified Blatt’s capsulodesis was performed in 3 cases including 2 cases of static scapholunate dissociation. Relief of pain, radiographic finding, range of motion, grip and pinch power were evaluated Result: In 7 cases definite relief of pain were seen and discomfort persisted in the others. Range of motion(flexion, extension) is improved 70% and 60% of uninjured side respectively at last follow-up. Grip and pinch power is also improved slightly. Carpal alignment were good in 10 cases except for 2 cases showing loss of parallel and there were clinical improvement without arthritic changes in all cases Conclusion: Surgical management of chronic scapholunate dissociation is also effective and essential procedure for not only functional improvement but also prevention of degenerative arthritis.
