Abstract
Forty-five hips were analyzed in 42 patients treated with total hip replacements (THR) after earlier intertrochanteric osteotomies. At time of osteotomy, the patients' mean age was 50 years (range: 14 to 65). Total hip replacement was performed at a mean interval of 11.9 years later (standard deviation: 7.7). Narrowing or closure of the medullary canal made insertion of the prosthesis stem difficult in 10 cases. After THR, the patients were followed for a mean of 6 years (range: 3 to 11). At follow up, the hips had a mean Mayo score of 81 (SD = 13) points (17 excellent, 12 good, 7 fair, 9 poor). The failure rate was 6.7%. Being overweight had an adverse effect on outcome. Intertrochanteric osteotomy may impair results after subsequent THR.
