目的 通过对臀大肌的形态学观测 ,以其对臀肌挛缩症松解术提供基础数据。方法 用15具红色乳胶液动脉灌注的尸体作双侧臀部解剖 30例 ,解剖观察臀大肌及其周围结构 ,测量臀大肌起止点 ,覆盖范围及观察滋养血管及坐骨神经和臀大肌的关系。结果 臀大肌呈菱形、上缘长约 9.1cm、下缘长约 10 .3cm、止点宽约 9.8cm、臀大肌血供来自臀上下动脉浅支 ,在内侧缘 1/ 3的深面进入 ,臀大肌神经支配来自于臀下神经。结论 臀肌挛缩症患者手术切口选择应沿臀大肌纤维走行方向 ,在中部为佳 ,因该部血管稀少
Objective To observe the morphology of the gluteus maximus and provide the basic data for the gluteal muscle contracture lysis. Methods Fifteen cadaveric anastomoses were obtained from 15 arteries infiltrated with red latex. Anatomy of the gluteus maximus and its surrounding structures were observed. The relationship between the starting and ending points of the gluteus maximus, the coverage, and the observation of nourishing vessels and the sciatic nerve and gluteus maximus . Results The gluteus maximus was rhombic with the upper margin of about 9.1cm and the lower margin of about 10.3cm. The deadline was about 9.8cm. The gluteus maximus blood supply was from the superficial branch of the superior and inferior gluteal artery. Into the gluteus maximus innervation from the inferior gluteal nerve. Conclusion Gluteus contracture patients surgical incision selection should be along the gluteus maximus fiber walking direction, in the middle is better, due to the Department of vascular thinning
