摘　　要：目的 :提供以旋股外侧动脉降支骨膜支骨膜瓣转位治疗股骨颈骨折、股骨头缺血性坏死和股骨干中下段骨不连的解剖学基础。方法 :在 3 2侧灌注红色乳胶的成人标本上 ,对旋股外侧动脉降支骨膜支的起始走行、分支分布进行解剖学观测 ;2侧新鲜标本注入墨汁观察骨膜支的供血范围。结果 :88%的降支发自旋股外侧动脉 ,其骨膜支于降支起始 4.0± 1.1cm处发出 ,外径 1.2± 0 .5mm ,长 7.1± 1.8cm ,经股内侧肌与股中间肌之间或穿股中间肌 ,分布于股骨中上段前内侧骨膜。结论 :以旋股外侧动脉降支骨膜支为蒂的骨膜瓣 ,可顺行修复股骨头颈骨折 ,逆行修复股骨中下段骨不连、股骨头缺血性坏死。Objective:To provide anatomic basis for transposition of periosteal flap pedicled with descending branch of lateral femoral circumflex artery(LFCA) in treating femoral neck fracture,ischemic necrosis of femoral head and bone nonuninon of infermiddle shaft of femur.Methods:The origin,course and branch′s distribution of LFCA were observed on 32 sides adult low extremity specimens.Blood supply area of periosteal branch was observed on 2 sides fresh specimens injected with black ink.Results:The descending branch originated from LFCA in 88% of the specimens,the periosteal branch,which is 1.2±0.5 mm in diameter and 7.1±1.8 cm in length originated from descending branch 4.0±1.1 cm below it divided from LFCA.It distributed to antero medial periosteum of proximal or middle part of femur.Conclusion:Periosteal flap pedicled with descending branch of LFCA could repair femoral neck fracture,nonunion of middle of distal femur and ischemic necrosis of femoral head.
