During the period from 1985 to 1991, 24 dislocated hips in 16 patients, all above the age of 3 years, were treated surgically in the New Children Hospital and Kasr El-Aini Hospital, Cairo University.
All patients were treated by open reduction and femoral varus derotation osteotomy. The average age at operation was 4.5 years. The follow-up period ranged from 1.5 to 6.5 years with an average 3.5 years. According to the radiographic classification system of Severin, there were 12 hips rated as grade I, 6 grade II, 4 grade III and 2 hips as grade IV. Clinically, 16 hips were excellent, 4 hips rated as good, 2 fair and 2 poor, following McQais criteria of clinical grading. Avascular necrosis developed in 3 out of the 24 hips. The follow-up period was not long enough to predict the ultimate fate of many of these hips. However, the radiographic results were good
