[Osteotomies for acetabular dysplasia in adults and adolescents]

The aims of treatment for acetabular dysplasia are the normalization of the relationship between the femoral head and acetabulum on weight bearing position, and to provide a painless, stable, and functional hip in the long-term. The reason of this abnormal relationship may arise either from the acetabulum (deficiency, maldirection) or the femoral head (aspheric, subluxation, valgus, varus). For this reason, preoperative planning, assessment, and patient selection are very important. Acetabular dysplasia is the main reason for hip osteoarthritis. Overcorrection is an important complication of acetabular osteotomies. This review summarizes different kinds of acetabular osteotomies with relevant presentation of our technique.
