Example of postoperative radiographs and three-dimensional CT. A 23-year-old female presented with cam-type femoroacetabular deformity and acetabular hip dysplasia. Radiographs and three-dimensional CT images were taken 1 week after curved periacetabular osteotomy. (A) The centre-edge angle and acetabular roof obliquity were 33.0° and 0°, respectively. (B) The alpha angle was 40.0°. (C) The arrow indicates the spherical junction of the femoral head-neck on a three-dimensional CT image after curved periacetabular osteotomy and osteochondroplasty.
