Figure 2 Postoperative follow-up imaging and functional recovery of the affected limb.(A, B) X-ray images on postoperative day 2 show good fracture reduction and proper positioning of the internal fixation. (C, D) X-ray images at 1 month after surgery show minimal callus formation with the internal fixation device in place. (E, F) X-ray images at 3 months after surgery show a significant increase in callus at the fracture site. (G–I) X-ray images and functional assessment at 4 months after surgery show further increase in callus and blurring of the fracture line. Functional images demonstrate significant hip and knee flexion, indicating good functional recovery of the affected limb. (J–M) X-ray images and functional assessment at 6 months after surgery show complete disappearance of the fracture line and good fracture healing. The patient is able to squat and walk freely, indicating excellent functional recovery of the affected limb.
