[Surgical treatment of epiphysiolysis of the hip].

Surgical treatment of aseptic necrosis of the femoral head is discussed. Results of 30 hip procedures performed in 26 patients, followed up for a variable period from 8 months to 8 years after the first visit, are reported. The importance of early diagnosis is stressed. Surgery is recommended as the only suitable treatment. It aims to reduce and re-form the femoral head in acute cases and to stabilize and correct the displacement in the less rapidly progressive forms. Cases were divided into 3 groups according to the degree of displacement (less than 30 degrees, from 30 degrees to 45 degrees and greater than 45 degrees). Fixation in situ was carried out in the first group and Imhauser's three-dimensional intertrochanteric osteotomy and osteotomy of the head and neck of the femur in the second and third group respectively. Good results were obtained in 23 (76.6%). In the other 7 cases (23.4%) the outcome was unsatisfactory.
