(A) A radiograph of a 16-year old male with bilateral protrusio acetabuli and coxa vara with right-sided medial joint space narrowing is shown. The preoperative radiographs demonstrated a pincer acetabulum with a horizontal roof, and therefore, an acetabular reorientation would not address the underlying pathomorphology. (B) Radiographs at 2 years after surgery on the right side and 1.5 years on the left side demonstrated rim trimming with circumferential bone anchors after labral refixation. The right hip revealed a slight increase in medial joint space. The 30° valgus osteotomy improved the joint clearance substantially resulting in markedly improved ROM.
