Attempted scapholunate arthrodesis for chronic scapholunate dissociation.
We report a retrospective review of seven patients with chronic scapholunate dissociation treated with attempted scapholunate arthrodesis. All procedures were done between 1978 to 1983 by one surgeon. Seven patients with follow-up of nine months or greater were available for review. Follow-up for the four patients with successful operations averaged seventy-seven months. Average age was 34 years (range from 19 to 46). Only one patient demonstrated radiographic fusion. Of the remaining six patients, three had no further wrist pain. The other three operations were total failures requiring other procedures for pain relief. For all patients, flexion-extension are decreased an average of 4 degrees. Grip strength averaged 88% of the unaffected side. Lateral scapholunate angle improved from an average preoperative angle of 70 degrees to a postoperative angle of 59 degrees. We conclude that this procedure is not a predictable method to treat scapholunate dissociation.
