In 1969 Nishio devised transtrochanteric curved varus osteotomy in the treatment of subluxation of the hip. We performed this procedure on 50 hips in 46 patients from 1976 through 1987 at our hospital. We studied 34 hips in 30 patients in these patients which were followed for more than 2 years.
Radiological results showed that 19 hips were good. 12 hips were poor and other 3 hips had little change. Poor group in radiological results did not remark improvement of pain score in clinical results. 3 hips showed femoral head necrosis and another 3 hips showed lateral subluxation of the head. This procedure has been useful to early stage of osteoarthritis with subluxation of the hip, especially unilateral type.
