Abstract
Extension contracture of the metacarpophalangeal (MP) joint can impede grasping and pinching function. When non-operative measures fail to gain flexion of the joint, surgical intervention is sometimes required. We report two cases for which capsulectomy of the MP joint was performed because hand therapy and splinting for over six months had not been sufficiently effective. A dorsal approach was applied in both cases. We resected the dorsal capsule and released the bilateral collateral ligaments of the MP joint and volar pouch. Transient pin fixation of the MP joint was applied for one week, and after removal of the pin, hand therapy was initiated. Reacquisition of flexion was satisfactory, but there was slight residual extension lag. Grasping and pinching function in both patients was improved adequately, and they were satisfied with the outcome.
