解剖、观察、测量了100侧半腱肌的形态,血管和神经。半腱肌是一块位于股后部的长梭形肌,其血液供给来自旋股内侧动脉7.％、臀下动脉4.7％、股深动脉2.8％、第一穿动脉67.8％、第二穿动脉8.6％、第三穿动脉5.8％、股动脉3.7％和腘动脉0.6％。根据营养动脉的数目和来源将其血供分为四个类型和若干亚型。半腱肌的神经来自坐骨神经分支,接受2支神经占62％,每支神经在入肌之前再分成2—3小支伴血管入肌肉。根据半腱肌的形态大小和血液供给特点,认为该肌是一块可作成肌瓣或肌皮瓣转移用的良好供肌。
Anatomical, observational, and measured the shape of the semitendinosus 100 muscles, blood vessels and nerves. The semitendinosus muscle is a long fusiform muscle located in the posterior part of the femoral artery. The blood supply comes from 7.% of the medial femoral artery, 4.7% of the inferior gluteal artery, 2.8% of the deep femoral artery, 67.8% of the first perforating artery, 8.6%, the third perforating artery 5.8%, femoral artery 3.7% and popliteal artery 0.6%. Blood is divided into four types and several subtypes based on the number and source of vegetative arteries. The nerve of the semitendinosus is derived from the sciatic nerve branch, which receives 62% of the 2 nerves, and each nerve is subdivided into 2-3 small branches with blood vessels into the muscle before entering the muscle. According to the shape and size of the semitendinosus and the characteristics of the blood supply, the muscle is thought to be a good donor muscle that can be used for the transfer of muscle flap or myocutaneous flap.
