Postoperative images of same 28-year-old woman confirm maintenance of correction and near-complete radiographic healing at four months postoperatively. She was clinically healed. She had discontinued crutch use at three months and was symptom-free. Left periacetabular osteotomy planned: (a) anteroposterior view confirms healing and correction. There is no crossover sign. Lateral centre-edge (CE) angle measures 25° (normal is about 25° to 35°). Roof angle is 4° (normal is about 0° to 10°). Shenton’s line is intact; (b) faux profil view reveals anterior CE angle is 28° (normal is about 20° to 35°).
