Replantation of the upper extremity severed at the level of the ulnar joint.

Two cases of upper extremity replantation at the level of the ulnar joint are presented. In both cases, the ulnar joint and adjacent anatomic functional structures were destroyed in accidents and excised during surgery. Some functional rehabilitation of the replanted extremities was obtained. In one case, the grasp function of the hand was recovered through primary use of the muscular apparatus of the upper arm. In another patient, the function of the lost ulnar joint was restored through microsurgical autotransplantation of the vascularized first metatarsophalangeal joint of the foot.
