解剖了80侧成人下肢,观察和测量了旋股外侧血管及其供养的股直肌和阔筋膜张肌,讨论了有关的应用解剖学问题。多数旋股外侧动脉发自股深动脉(89.7％)。旋股外侧动脉干的长度平均为16毫米,外径为5.5毫米。旋股外侧动脉的分支型主要为升降型(77.5％),其次为升横降型和横降型。升支长平均为87毫米,根部外径为3.5毫米。伴行静脉一条或两条。升支可作为阔筋膜张肌肌皮瓣的血管蒂,其末端可植入股骨头或股骨颈内,以治疗缺血性坏死或骨折不愈合。降支长平均为200毫米,外径为3.5毫米。伴行静脉略粗于动脉。降支是股前部的一个多用血管,既可作为受区血管,又可将其末端植入股骨干或下端骨折处,以治疗骨折不愈合。股直肌主要有两组血管神经束。第一组的血管较短且细,不宜作为吻接血管。第二组血管神经束是股直肌的主要血管神经束。供养阔筋膜张肌的血管蒂动脉的长度平均为50毫米,外径为3.0毫米;伴行静脉一条或两条,略粗于动脉。阔筋膜张肌可制成一个相当大的肌皮瓣,也可将其下端及髂胫束移位缝接于髌上缘,以增强对髌骨的拉力和矫正拉力方向,合理恢复伸膝的功能。
Anatomy of 80 adult lower extremities, the lateral femoral circumflex femoral vessels and their rectus femoris and tensor fascia lata were observed and measured, and relevant anatomic problems were discussed. The majority of the lateral femoral arteries originated from the deep femoral artery (89.7%). The average length of the circumflex artery trunk is 16 mm and the outer diameter is 5.5 mm. The branches of the lateral femoral circumflex artery were mainly ascending and descending type (77.5%), followed by ascending and descending type and descending type. Ascending average length of 87 mm, the root diameter of 3.5 mm. Accompanied by one or two veins. Ascending branch can be used as the fascia lata myocutaneous flap vascular pedicle, the end of the femoral head or femoral neck can be implanted in order to treat ischemic necrosis or fracture nonunion. Down an average length of 200 mm, an outer diameter of 3.5 mm. Associated vein slightly thicker than the arteries. Descending branch is an anterior multi-use blood vessels, both as the affected area of blood vessels, but also the end implants into the femoral shaft or lower fracture, to treat fracture nonunion. Rectus muscle has two main groups of vascular nerve bundle. The first group of blood vessels shorter and thin, not as a kiss of blood vessels. The second group of vascular bundles is the main vascular bundle of the rectus femoris. The length of the vessel pedicled artery that supports the tensor fascia lata muscle is 50 mm on average with an outer diameter of 3.0 mm; one or two accompanying veins, slightly thicker than the artery. Tensor fascia lata muscle can be made of a considerable muscle flap, but also the lower end of the iliotibial band displacement and sutured in the upper edge of the patella to enhance the pull of the patella and straighten the tension direction, a reasonable recovery of knee extension Features.
