A female patient underwent a Pemberton acetabuloplasty on the left side at the age of 2 years. Her false profile radiographs obtained 15 years after surgery showed typical increased anterior coverage. Shown are the (A) vertical-center-anterior margin angle, (B) anterior acetabular head index, and (C) weightbearing zone acetabular index of the right hip, which was the nonoperated side, and the (D) vertical-center-anterior margin angle, (E) anterior acetabular head index, and (F) weightbearing zone acetabular index of the left hip which was the surgically treated side.
