Neer hemiarthroplasty and Neer total shoulder arthroplasty in patients fifty years old or less. Long-term results.
Seventy-eight Neer hemiarthroplasties and thirty-six Neer total shoulder arthroplasties were performed at our institution, between January 1, 1976, and December 31, 1985, in ninety-eight patients who were fifty years old or less. Two patients (two shoulders) died, and four patients (four shoulders) were lost to follow-up. The remaining seventy-four hemiarthroplasties (95 per cent) in sixty-four patients and thirty-four total shoulder arthroplasties (94 per cent) in thirty-one patients were included in the clinical analysis as the preoperative and operative records were complete and the patients had been followed for at least five years (mean, 12.3 years) or until revision. ⋯ The risk of revision was higher for the seven shoulders that had had a tear of the rotator cuff at the time of the operation than for the twenty-seven that had not had one (p = 0.029). The data from the present study indicate that a shoulder arthroplasty provides marked long-term relief of pain and improvement in motion; however, nearly half of all young patients who have a shoulder arthroplasty have an unsatisfactory result according to a rating system. Care should be exercised when either a hemiarthroplasty or a total shoulder arthroplasty is offered to patients who are fifty years old or less.
