title: Comparison of preoperative, intraoperative and early postoperative total hip replacement with and without trochanteric osteotomy.
abstract: A series of 100 consecutive patients with total hip replacements in whom trochanteric osteotomy was performed was compared with 100 patients in whom the greater trochanter was left in place. The groups were comparable with respect to age and incidence of osteoarthritis and connective tissue disorders. Although no statistically significant difference was noted among trochanterectomy groups or disease subgroups in terms of preoperative impairment as indicated by preoperative Harris score, 16 patients presented exposure problems necessitating trochanteric osteotomy despite preoperative plans to leave the trochanter in place. Salvage operations after unsuccessful previous operations were performed in 18 patients in the osteotomy group and 11 in the nonosteotomy group. Mean operating time was 3 hours for patients in the osteotomy group and 2 hours for those in the nonosteotomy group. Considerably more intraoperative and postoperative blood replacement was required in the patients having osteotomy. Patients sat, stood, walked, and left the hospital sooner in the nonosteotomy group than in the osteotomy group. Trochanteric bursitis requiring treatment 3 or more months after operation occurred in 17 patients having osteotomy and in 3 patients not having osteotomy. Hematomas developed in 15 patients in the osteotomy group and in 4 in the nonosteotomy group. Ectopic bone formation was observed in 12 of the osteotomy group, 8 with limitation of function, and 5 of the nonosteotomy group; non had symptoms. Six osteotomized patients had troublesome abductor weakness secondary to wire breakage and proximal migration of the trochanter. The rates of infection and thrombophlebitis were low in both groups. When exposure was not difficult, leaving the trochanter intact had many advantages.
