Constrained total elbow arthroplasty.
In 1972, the senior author designed a condylar-sparing constrained hinge elbow prosthesis with a high-density polyethylene bushing. The condylar-sparing design allows both intercondylar and intramedullary fixation of the humeral component with methylmethacrylate cement. Reattachment of the muscles and collateral ligaments to the preserved condyles provides further stability. The clinical experience spans more than 16 years in 42 elbows with a relatively low loosening rate of 7%. The implant was removed and not replaced in three elbows: one for late infection, one for posttraumatic comminuted fracture of the distal humerus, and one for loosening of a humeral component. A series of 27 patients (31 elbows) with 24-204 months of follow-up study (average, 77 months) had excellent pain relief and an average range of motion of 129 degrees flexion, -44 degrees extension, 69 degrees pronation, and 61 degrees supination.
