Salter innominate osteotomy ( SIO ) has been performed in the treatment of developmental displasia of the hip ( DDH ) and Perthes disease for many years. It can restore the normal anatomy of the hip, adjust the biomechanical properties of the whole joint and promote the development of the hip by improving the geometrical relationship of the hip head. In order to better improve the hip function, some technical changes have been made in the angle of osteotomy, method of osteotomy and fixation materials. SIO combined with proximal femoral osteotomy is a better choice for DDH and Perthes disease in the patients with different indications. The postoperative rehabilitation is a key problem. In order to achieve good long-term curative effects, much attention should be paid to the restoration of the joint range of motion, joint stress, neuromuscular control and control of the posture and gait. A review about SIO is presented as following.
