  1. 第十节 臀部、股后区

  2. 一、皮肤切口 1.臀股沟作一横切口。 2.腘窝横纹作一横切口。

  3. 二、解剖程序 1.翻开皮肤。 2.浅筋膜内找: (1)臀上皮神经 (2)臀中皮神经:又名臀内侧皮神经 (3)臀下皮神经 (4)股后皮神经

  4. 3.清除浅、深筋膜。 4.分离臀大肌,切断起点,翻开。 5.清理臀大肌下结构: 1)臀上神经、动脉、静脉(外侧→内侧排列,与股神经、动脉、静脉同)→梨状肌上孔。 2)坐骨神经、股后皮神经、臀下神经、动脉、静脉、阴部内动脉、静脉、阴部神经 (外侧→内侧排列) →梨状肌下孔。 3)阴部内动脉、静脉、阴部神经(外→内)→坐骨小孔。

  5. 6.切断臀中肌,翻开,观察臀小肌、臀上神经、动脉、静脉。6.切断臀中肌,翻开,观察臀小肌、臀上神经、动脉、静脉。 7.观察上孖(zi或ma)肌、闭孔内肌、下孖肌、股方肌(上→下排列)。 8.清理股二头肌、半腱肌、半膜肌。 9.查看坐骨神经的行径、分支和穿动脉(股深动脉的分支)。
