Summary

Acetabular dysplasia often accompanies by acetabular bone hyperplasia and osteonecrosis of the femoral head. These pathological changes can alter the position of the center of the femoral head. Thus, measurement errors will be generated on the anteroposterior radiographs of the adult pelvis involving centre-edge angle, acetabular angle (Sharp angle), and acetabular head index, eventually resulting in the inaccurate diagnosis of acetabular dysplasia. Herein, the investigators describe the protocol to verify three novel X-ray indicators, including offshoring index (OFI), moving up index (MUI) and teardrop baseline offshoring index (TBOI) of the femoral head. All data will be expressed as relative ratios, as the investigators expect to make an accurate diagnosis through avoiding the generation of errors resulting from measurement angles.
