Hip joint preserving osteotomy surgery is the treatment of choice for young patients with early symptomatic structural abnormalities of the acetabulum and proximal femur. This is true even in the absence of severe secondary degenerative changes. These disorders can include hip instability from classic developmental dysplasia, post-traumatic acetabular dysplasia, hip impingement from retrotorsional acetabular deformities, or, rarely, post-traumatic problems. During the past 20 years, various techniques of acetabular and proximal femoral reorientation have evolved, making the procedure reliable, reproducible, and durable. In this report, the current indications and results of acetabular and proximal femoral osteotomies in patients with symptomatic acetabular structural problems will be discussed.
