Salter innominate osteotomy for treatment of developmental dysplasia of the hip.

PURPOSE To compare the results of Salter innominate osteotomy (SIO) for treatment of developmental dysplasia of the hip (DDH) in children. METHODS Between 1994 and 2002, 53 girls and 8 boys with DDH underwent open reduction and SIO; 21 were on the left side, 22 on the right side, 18 bilateral. They were divided into 2 groups: group 1 included 35 patients aged younger than 3 years (46 hips) and group 2 included 26 patients aged 3 years or older (33 hips). Clinical outcomes were assessed using the modified McKay criteria to measure pain symptoms, gait pattern, Trendelenburg sign status, and the range of hip joint movement. Radiographic outcomes were evaluated using the Severin method to measure the Sharp acetabular angle and the centre-edge angle. RESULTS Group-1 children achieved slightly better reduction and stabilisation of the hip joint empirically, but clinical and radiographic results and complication rates in the 2 groups were not significantly different. CONCLUSION Open reduction and SIO without preoperative traction is effective for the management of DDH in children younger than 6 years.
