Objective: To compare the clinical efficacy of rotational osteotomy at the base of femoral neck and iliac bone flap transfer with ascending branch of lateral femoral circumflex artery(vascularized iliac bone flap transfer) in the treatment of ARCO III stage, CJFH-L type osteonecrosis of femoral head. Methods: We compared 25 cases (Group A), in which 25 hips underwent rotational osteotomy at the base of femoral neck and 25 cases (Group B) , in which 25 hips underwent vascularized iliac bone flap transfer in our hospital from September 2017 to March 2024.The operative time and hospitalization time were compared, the collapse and repair of femoral head and the healing of osteotomy were evaluated, and the reasons of failure were analyzed.
