Typical case two: A 45-year-old man presented with double column fractures of the left acetabulum following a fall from a height. The operation was performed 23 days after the injury. The function of the injured joint was similar to the normal side 12weeks after acetabular tridimensional memory alloy-fixation system (ATMFS) internal fixation. Matta’s X-ray evaluation was scored as excellent, and d’Aubigne and Postel’s clinical outcome evaluation was scored as excellent at the last follow-up (95 months postoperatively). a, b X-ray and three-dimensional computed tomography (CT) of the complicated acetabular fracture before the operation; c postoperative X-ray
