在30例成人下肢标本上,观察了股外侧肌的形态、血供和神经支配。肌的血供主要来自旋股外侧动脉降支。肌的神经来自股神经的一根较大的肌支。肌的下2/3具有较恒定的血管神经蒂,该蒂入肌后沿肌纤维长轴下行呈单干型、双干型和三干型分布。肌的下2/3有较恒定的肌皮动脉供养其表面的皮肤。本文讨论了股外侧肌皮瓣转位的应用解剖学要点。
In 30 adult lower extremity specimens, the shape, blood supply and innervation of the lateral femoral muscle were observed. Muscle blood supply mainly from the femoral circumflex artery descending branch. Muscle nerves come from a larger branch of the femoral nerve. Muscle under 2/3 has a more constant vascular neurosensory, the pedicle into the muscle along the long axis of muscle fiber was dry type, double dry and dry distribution. The lower 2/3 of the muscle has a more constant muscular artery to support the skin on its surface. This article discusses the anatomic features of transposition of the lateral femoral skin flap.
