选用30侧经动脉红色乳胶灌注过的下肢标本,解剖观测了膝降血管的起始、走行位置、分支分布.膝降动脉于股骨内侧髁内下缘上方115、2±15.6mm处,起于股动脉,外径2.3±0.4mm.膝降动脉关节支或发自股动脉的关节支是股骨内侧髁前内侧面60mm×30mm区域的主要供血动脉.根据解剖结果,设计了带膝降血管蒂股骨内侧髁骨(膜)瓣移位修复股骨中下段骨不连或骨缺损.
Thirty cases of lower limbs infused with red latex were selected for anatomical observation of the origin, location and branch distribution of the knee-descending vessels.The knee-descending artery was located at 115,2 ± 15.6mm above the medial inferior edge of the medial femoral condyle, Femoral artery, diameter 2.3 ± 0.4mm. Articular branch of the knee descending artery or femoral artery is the main feeding artery in 60mm × 30mm anterior medial femoral condyle .According to the anatomy, Medial femoral medial condyle bone (membrane) flap displacement in the repair of femoral nonunion or bone defect.
