目的为儿童膝下外侧动脉蒂腓骨头骨骺皮瓣的设计提供应用解剖学基础。方法在22侧经动脉内灌注红色乳胶的2～16岁儿童下肢标本上重点观测膝下外侧动脉的起始、走行、分支、分布和吻合。结果膝下外侧动脉始于腘动脉,起点距腓骨头尖上方(1.6±0.5)cm,起始部外径(1.3±0.4)mm。从起点至第一下行骨膜支距离(2.5±0.6)cm,至第一皮支距离(2.9±0.2)cm。结论膝下外侧动脉可携带腓骨头及相应皮瓣。皮瓣面积最大约为10.0cm×6.0cm。
Objective To provide an anatomical basis for the design of the pedicled lateral fibular epiphysis flap of the lateral genicular artery. Methods The onset, course, branch, distribution and anastomosis of the lateral inferior genicular artery were observed mainly on the lower limbs of children aged 2 to 16 years with intra-arterial infusion of red latex. Results The inferior genicular artery originated from the popliteal artery. The starting point was 1.6 ± 0.5 cm above the tip of the fibula and 1.3 ± 0.4 mm in the initial part. The distance from the origin to the first descending periosteum was (2.5 ± 0.6) cm, and the distance to the first skin branch was (2.9 ± 0.2) cm. Conclusions The lateral inferior genicular artery can carry the fibula head and the corresponding flap. Flap area up to about 10.0cm × 6.0cm.
