解剖、观察、测量了40例缝匠肌的形态、血管和神经。缝匠肌的平均长度、宽度和厚度分别为529±8.48毫米、25.30±0.82毫米和10.5±0.66毫米。缝匠肌的动脉具有不同的起源。它们分别起于旋髂浅动脉(0.66%±0.46)、股动脉(58.36%±2.82)、股深动脉(3.93%±1.11)、旋股外侧动脉及其分支(13.44%±1.95)、膝最上动脉(20.98%±2.33)和腘动脉(2.62%±0.91)。缝匠肌的上部(长15厘米左右)主要由股深动脉和旋股外侧动脉的分支供给。缝匠肌的下部(长约20厘米),主要由膝最上动脉的分支供给。因此,可分别以上述血管为蒂,作成缝匠肌上、下转移瓣或游离移植用肌瓣与肌皮瓣。由于隐神经与膝最上动脉伴行,故肌的下部又可作成肌皮感觉瓣。每一缝匠肌可有动脉5～13支,平均为7.6支,它们大致均匀地分布于肌的全长,约每隔7厘米即有一支动脉,呈节段性分布。缝匠肌动脉的伴行静脉,多数只有一支,少数有2支,皆等于或大干动脉。缝匠肌的神经来自股神经。每一缝匠肌从股神经接受1～5支神经,以1～2支的最多。每支神经在入肌前又可分为1～7小支,以分为3～4小支的最多。
Anatomy, observation, measurement of 40 cases of sartorial muscle morphology, blood vessels and nerves. The average length, width and thickness of sartorius muscle were 529 ± 8.48 mm, 25.30 ± 0.82 mm and 10.5 ± 0.66 mm, respectively. Arteriosks have different origins of arteries. From the superficial iliac artery (0.66% ± 0.46), the femoral artery (58.36% ± 2.82), the deep femoral artery (3.93% ± 1.11), the lateral femoral artery and its branch (13.44% ± 1.95) Artery (20.98% ± 2.33) and popliteal artery (2.62% ± 0.91). The upper part of the sartorius muscle (about 15 centimeters long) is mainly supplied by the branches of the deep femoral and femoral circumflex femoral arteries. The lower part of the sartorius muscle (about 20 cm long) is mainly supplied by the branch of the superior arteries of the knee. Therefore, respectively, to the above-mentioned vascular pedicle, made of sartorius muscle transfer under the flap or free graft with muscle flap and myocutaneous flap. As the saphenous nerve and the knee with the most accompanying artery, so the lower part of the muscle can be made of myocutaneous sensory flap. Each sartorius muscle arteries can have 5 to 13, with an average of 7.6, they are roughly evenly distributed in the muscle length, about every 7 cm that is, there is an artery, was segmental distribution. Arteriatti artery accompanying veins, the majority of only one, a few have 2, are equal to or trunk artery. The sartorius muscle comes from the femoral nerve. Each sartorius muscle from the femoral nerve to accept 1 to 5 nerves to 1 to 2 up to. Each nerve in the muscle before can be divided into small branches 1 to 7, divided into 3 to 4 small branch up.
