title: Does trapeziectomy destabilize the carpus?
abstract: Trapeziectomy for the treatment of trapeziometacarpal arthritis is an in vivo model of an isolated lesion of the scaphotrapeziotrapeziod ligament complex. We analysed the radiological changes in the wrist retrospectively in 86 patients after trapeziectomy. On standardized PA and lateral films the revised carpal height ratio, the radiolunate angle, the scapholunate angle and ulnar translation were compared pre- and postoperatively. None of these parameters showed a statistically significant change after operation. Grouping the patients into shorter (< 36 months) and longer (> 36 months) follow-ups also failed to show any significant differences.
