本文作者经40具新鲜尸体的小腿解剖提出外侧踝上皮瓣是由腓动脉的穿支血管所供养。穿支血管在外踝上方5cm处,以胫腓韧带上缘的骨间膜穿出,分为浅皮支和深降支二支。前者在伸趾长肌和腓骨短肌肌间隙中穿过肌筋膜,进入皮肤向上供养小腿外下半部,从胫骨嵴到腓骨后缘的皮肤约12～18×9cm的范围。深降支在外踝前缘深筋膜下疏松组织中下行,沿(?) The author of this study was presented by calf dissection of 40 fresh cadaveric heads. The lateral malleolus flap was supported by perforating branches of the peroneal artery. Wearing branches in the lateral malleolus 5cm above the Department, to the tibiofibular ligament on the edge of the interosseous membrane piercing, divided into shallow skin branches and deep descending branch two. The former penetrates the myofascial space in the space between the extensor phalanges and fibula, and enters the lower part of the lower leg outside the skin, ranging from 12 to 18 × 9 cm from the tibial crest to the posterior edge of the fibula. The deep descending branch descending in the deep fascial tissue below the lateral margin of the lateral malleolus,
