Ganz Osteotomy

Also known as peri-acetabular osteotomy, this treatment is designed to reshape the hip joint for people with hip dysplasia. Osteotomy means the bone is divided and shifted to a better alignment. Sometimes osteotomy is recommended on both the socket and the ball side of the hip.

Surgery involves cutting the pelvis around the hip joint and shifting it into a better position to support the stress of walking. The positioning is held in place with screws until the bone heals. The screws can be removed later, but it is not necessary.


Patients are advised to not put full weight on their leg for up to three months. Therefore, crutches or a walker is recommended, and a wheelchair is needed for longer distances until the bone is healed in the new position. Full healing and recovery can take up to one year.
