We investigated whether the following acetabular scores influence operative outcomes in patients with developmental dysplasia of the hip who underwent Salter innominate osteotomy (SIO) or Pemberton osteotomy (PO): the acetabular depth ratio (ADR), the acetabular index, the center-edge (CE) angle of Wiberg, and the femoral head migration rate (Reimer's index). A total of 47 hips were treated with SIO and 50 hips were treated with PO. Changes in ADR were greater in children who underwent PO compared with those who underwent SIO. However, the acetabular index, the center-edge angle, and Reimer's index did not differ between the groups at final follow-up. Children who underwent PO achieved an improved radiological ADR compared with those who underwent SIO on an average follow-up of 5 years after innominate osteotomy.
