Acetabular osteotomy: indications and results.

Acetabular osteotomy is the treatment of choice for young patients with symptomatic structural abnormalities of the acetabulum in the absence of severe secondary degenerative changes. These disorders can include hip instability from classic developmental dysplasia or posttraumatic acetabular dysplasia, hip impingement from retrotorsional acetabular deformities, or rarely, posttraumatic problems. During the last 15 years, various techniques of acetabular reorientation have evolved, making the procedure reliable, reproducible, and durable. In this report, the current indications and results of acetabular osteotomy in patients with symptomatic acetabular structural problems will be discussed.
