目的 为隐血管蒂股骨内侧髁骨 (膜 )皮瓣逆行移位修复小腿中上段损伤提供应用解剖学基础。方法 在 3 2侧经动脉灌注红色乳胶的成人下肢标本上 ,解剖观察了隐血管的起源、走行、分支、分布和吻合情况。结果 在 84.3 3 %的情况下隐动脉起源于膝降动脉 ,膝降动脉发出关节支后主干延续为隐动脉。隐动脉终末支在小腿内侧胫骨粗降水平与膝下内侧动脉皮支和胫后动脉肌间隙支有恒定的吻合。结论 隐血管蒂股骨内侧髁骨 (膜 )皮瓣逆行移位可以修复小腿中上段骨与软组织缺损。
Objective To provide an anatomical basis for the repair of the upper mid-leg injury by the retrograde transposition of the medial femoral condyle (flap) of the femoral pedicle. Methods The origin, course, branch, distribution and anastomosis of occult blood vessels were observed anatomically on the adult lower extremity specimens with arterial red blood perfusion on the 32 sides. Results In 84.3% of the cases, the saphenous artery originated in the knee descending artery, and the descending artery descended from the main branch of the articular branch to the saphenous artery. The descending level of the saphenous artery distal branch in the calf medial tibia has a consistent anastomosis with the medial branch of the medial artery and the posterior tibial artery. Conclusions The retrograde transposition of the medial femoral condyle (flap) of the femoral pedicle can repair the defect of the upper middle part of the lower leg.
