Total elbow arthroplasty for complete ankylosis of the elbow

Abstract

Sixteen patients who received nineteen semiconstrained total elbow replacements for complete ankylosis of the elbow were followed for an average of five and three-quarters years (range, two to twelve years). The average preoperative elbow score was 23 points and the average postoperative score was 84 points. Postoperatively, the average flexion was 115 degrees; extension, 35 degrees; and pronation and supination, 95 degrees. There were fifteen excellent or good results. There was one failure due to a deep infection, but after removal of the prosthesis a satisfactory fascial arthroplasty was achieved in this elbow. Function was improved in all patients, and all patients had relief of the preoperative pain. For the arthroplasty to succeed, the patient must have a good understanding of the procedure and must be willing and able to comply with the postoperative rehabilitation program. The use of a semiconstrained, often custom-fit, implant is necessary. The Bryan-Morrey posteromedial approach to the elbow is recommended for the procedure, since this approach allows early institution of range-of-motion exercises.
