Comparison of the effects of expanded core decompression bone grafting and musculoskeletal flap implantation in the treatment of the femoral head necrosis
Objective To compare the clinical efficacy of expanded core decompression bone grafting and musculo-skeletal flap implantation in the treatment of femoral head necrosis.Methods The 27 patients with femoral head ne-croses were divided into expanded core decompression bone grafting group(10 cases)and musculoskeletal flap im-plantation group(17 cases),according to different surgical methods.The operation conditions of the two groups were recorded.The pain relief of patients was evaluated by pain VAS,and the functional recovery of hip joint was evaluated by Harris score.Results All patients were followed up for 12～48 months.Operative time,intraoperative blood loss,incision length and hospitalization time were shorter(less)in the expanded core decompression bone grafting group than those in the musculobone flap implantation group(P＜0.01).Pain VAS:at 1,3 and 12 months after surgery,they were lower than those before surgery(P＜0.05),and there were no statistical differences between the two groups at various time-point after surgery(P＞0.05).Harris scores:at 1,3 and 12 months after surgery,they were higher than those before surgery,there were no statistical differences between the two groups at various time-point after surgery(P＞0.05).At the last follow-up,X-ray films of both groups showed no progression in the necrotic area of the femoral head.All patients could walk normally,except for 2 cases with mild claudication in the musculoskeletal flap implanta-tion group,the other patients could walk with normal gait.Conclusions Both expanded core decompression bone grafting and musculoskeletal flap grafting can achieve satisfactory clinical results in the treatment of femoral head nec-rosis.The surgery of expanded core decompression bone grafting is less trauma,less bleeding and faster recovery.
