Abstract: Transtrochanteric rotational osteotomy was performed on 22 hips in 17 patients with osteonecrosis of the femoral head. Ten were male and seven female, with a mean age at surgery 36.3 years (ranging from 17 to 66 years). Follow-up periods ranged from two to 7.8 years (average 4.7 years). Osteonecrosis was induced by steroid drugs in 11 hips and non-steroids 11 hips (six idiopathic, four alcohol abuse and one trauma).Postoperative progressive collapse occurred in three steroid group hips and two hips of the non steroid group, which were chiefly dependent on the small ratio of transposed intact articular surface to the weight-bearing area.Postoperative complication was subcapital fracture in two hips in the steroid group which were cases of systemic lupus erythematosus with bilateral operated hips. In the non-steroid group two hips developed subcapital fractures or varus deformity of the osteotomy site, due to insufficiency of fixation of the osteotomy site.
