股骨上段骨折后骨不连,肿瘤切除后骨缺损等需移植骨块填充修复,恢复下肢功能.本研究采用旋股内侧动脉深支为蒂的大转子骨瓣转位修复股骨上段骨不连、骨缺损或吻合血管移植修复其它部位骨缺损等,具有可行,供临床骨外科开展新的供骨区和术式时参考.1 材料和方法研究用经甲醛常规固定并经红色乳胶动脉内灌注过的成人下肢标本40侧.仔细解剖出旋股内侧动脉深支及大转子支,观察了其走行、位置、分支及分布.用电子数显卡尺测量了有关数据和血管的供骨范围,经统计学处理,依据手术设计,在尸体标本上进行了手术模拟试验.2 结果2.1 旋股内侧动脉 旋股内侧动脉深支发出后,恒定地经短收肌与闭孔外肌之间达髋关节后方,继经股方 Femoral nonunion after fracture of upper femur and bone defect after resection of tumor need to be filled with bone graft to restore and restore the function of lower extremities.In this study, Bone defect or anastomosis vascular graft to repair other parts of the bone defect, feasible, for clinical orthopedics for the new bone area and surgical reference.Materials and methodsFormal fixation with formalin by red latex intra-arterial infusion Of the adult lower extremity specimen 40. The deep branches and the greater trochanter branch of the medial arteries were carefully dissected and their movement, location, Learning treatment, based on the surgical design, in the corpse specimens were performed on the surgical simulation test.2 results 2.1 spinus medial femoral circumflex artery after the deep branches of the medial branch issued, the constant between the short musculature and obturator muscle reach the rear of the hip Following the stock side
