Treatment of Severe Hip Dysplasia with Leg Length Discrepancy Using Spherical Periacetabular Osteotomy

Figure 1

A 20-year-old woman with severe acetabular dysplasia. (a) Preoperative anteroposterior radiograph of the left hip joint, (b) preoperative CT coronal view, and (c) preoperative 3D-CT frontal view. Compatibility of the left hip joint was poor, and the femoral head of the superior acetabular coverage was insufficiently covered. (d) The abduction radiograph of the left hip shows good compatibility with the left hip joint. (e) The distance of leg length discrepancy from the center of the lesser trochanter to the bottom of the ischial tuberosity was 17.6 mm.
