在３０侧成人下肢标本上，观察了跟骨内侧和上腿内侧下１／３筋膜血管来源与分布情况，其中分布到跟骨内侧的滋养动脉主要来自足底外侧动脉与胫后动脉的分支，分别发出３～９支和２～５支外径０．６±０．４ｍｍ的骨支。小腿内侧下１／３筋膜的血供来自胫后动脉的肌间隙筋膜皮动脉，有１～３支，外径０．８±０．５ｍｍ。踝管区的骨皮支与肌间隙动脉的下行支相吻合。根据供区解剖学规律，充分利用筋膜血管明显纵向分布的特点，设计带筋膜蒂跟骨瓣，转位修复内踝骨折、骨不连。
In 30 adult lower extremity specimens, the source and distribution of 1/3 fascia in the medial calcaneus and the medial upper leg were observed. The nodal artery distributed to the medial calcaneus mainly came from the branches of lateral plantar artery and posterior tibial artery , Were issued 3 to 9 and 2 to 5 external diameter 0.6 ± 0.4mm bone graft. Lower third of the medial leg fascia blood supply from the posterior tibial artery muscle interstitial fascia skin artery, 1 to 3, diameter 0.8 ± 0.5mm. The ankle area of the pericardium branch and the descending branch of the intermuscular artery anastomosis. According to the rules of anatomy for the area, taking full advantage of the longitudinal distribution of fascia vessels, the pedicle flap pedicled with fascia was designed to repair the medial malleolus fracture and nonunion.
