More and more patients with old acetabular fracture were admitted in our institution during the past years. There is little literature especially depicts the therapeutic principle of the kind of damage. Posterior wall osteotomy would be conducted to eliminate the fragments or callus from the hip joint. Then, the deformed healing acetabulum could become mobile and the reduction may be achieved.

The function outcome is evaluated with HHS score at the follow up.
