*2.3. Postoperative Care and Evaluation*

Postsurgical clinical evaluation of rotational correction involved comparison of foot rotation and internal and external rotation of the hip joint between the affected and unaffected limbs while the patient was still in the supine position on the table. Based on the patient's level of tolerance, range of motion was resumed slowly, and all patients were allowed use of partial weight-bearing crutches.

Postoperative CT scans were used to compare the angles (angle-CT), and a maximum difference of 5◦ was considered acceptable. The correlation between angle-SP (measured intraoperatively with the SP app) and angle-CT (measured postoperatively using a CT scan) was assessed.

Clinical follow-up was carried out 1, 2, and 3 months postoperatively, and every 3 months thereafter until bone union was achieved. Radiographic evaluation was carried out at each visit, and bone union was defined as the presence of an appropriate bridging callus and resolution of persistent fracture lines in at least 3 out of 4 radiographic views.

All patient radiographs were assessed by two independent board-certified orthopedic surgeons.
