title: [Adaptation osteotomy in idiopathic femoral head necrosis].
abstract: Thirty-nine patients who suffered a segmental ischemic necrosis of the hip, fifteen of which affected on both sides, were treated with osteotomy of the femur. The re-examinations were carried out after an average period of 6.6 (2.5-12) years. While in twenty one cases, the hip necrosis was treated exclusively by varisation, in thirty three cases a combination of varisation and flexion was effected. 12 patients (equivalent to 22.2%), all of them with a necrotic angle of more than 115 degrees, were provided with a total hip arthroplasty in the interval. The patients with a necrotic angle smaller than 115 degrees showed a definite alleviation of the pain symptoms, an increased hip flexibility and an improved locomotory pattern.
