Postoperative CT showing poor fixation with memory alloy embracing device. (A) The embracing device failing to adequately embrace the upper and lower edges of the rib and partially detached, causing the fractured end of the fracture to angled downward (blue arrow). (B) The embracing device does not match the size of the rib, resulting in unstable and angled downward of the fracture ends (yellow arrow). (C) Poor placement of the embracing device, with the front end too close to the fracture line, resulting in unstable fixation and dislocation of the fractured end (white arrow).(D) The embracing device is stable, but the fractured end is misaligned backward (red arrow)
