Outcome of Copeland surface replacement shoulder arthroplasty.
We report the outcome of humeral head surface replacement hemiarthroplasty performed at our institution using the Copeland prosthesis. We followed 56 shoulders (52 patients) for a mean of 34.2 months (range, 24-63 months). Two were lost to follow-up, and there were six deaths unrelated to the shoulder surgery. Preoperative diagnoses in the remainder were osteoarthritis (20), rheumatoid arthritis (26), rotator cuff tear arthropathy (1), and post-traumatic arthrosis (1). The mean age was 68 years. Constant scores for the whole group improved from a mean preoperative score of 16.4 (range, 8-36) to 54.0 (range, 20-83) at last follow-up (P < .05). Three cases underwent subsequent arthroscopic subacromial decompression for impingement symptoms. One case required revision for aseptic loosening to a stemmed implant. Contained, nonprogressive osteolysis was seen in 2 cases. One periprosthetic humeral neck fracture was managed successfully nonoperatively. These results are comparable to those obtained with a modern stemmed hemiarthroplasty and are similar to Copeland's own series.
