【摘要】 目的:为应用第一穿动脉血管蒂骨瓣转位修复股骨上段骨缺损提供解剖学依据及手术方法。方法:在40侧成人下肢标本上,解剖观察了第一穿动脉的分支分布及吻合特点。结果:发现股深动脉于小转子尖下方4.5±1.3cm处发出第一穿动脉,外径为2.8±0.7mm。第一穿动脉分为升支和降支,升支走向大转于方向,发出外径1.0mm以上的肌骨膜支,分布于臀大肌下部和大转子等处,并参与十字吻合;降支粗长,参与股骨后部血管链的形成。自1991年始,以第一穿动脉为蒂切取骨瓣转位修复股骨上段骨缺损12例,疗效满意。结论:第一穿动脉为蒂的骨瓣,用于股骨颈、股骨距和股骨上段骨缺损的修复,疗效可靠。更多还原

【Abstract】 Objective :T supply anatomical basis and operative method for the repair of upper femur incomplete with vessel pedicled bone flap of first perforating artery. Methods: The branch and anastomotic features of the first perforating artery were observed in 40 adult samples of bwer limbs. Results: The first perforating artery was issued from deep femoral artery 4. 5 ± 1. 3cm under the tip of minor trochanter. Its outside diameter was 2.8 ±0.7mm. It was divided into two branches:ascending branch and descendign branch. Ascendign branch went towards greater trochanter and issued muscle and periost branches outside diameter over 1mm, which were distributed among lower greatest gluteal muscle and greater trochanter and joined cross connection. Descending branch was wider and longer and joined the formation of vascular chain behind femur, since 1991,12 patients who had upper femur incomplete hade been repaired with vessel pedicled bone flap of the frist perforating artery and received good effect. Conclusion:The first perforation artery vessel bone flap can be used in repairing neck of femur, femorale calcar and upper femur incomplete.更多还原
