在40侧标本上解剖观测了供应大转子的血供来源。大转子后部的动脉发自旋股内侧动脉深支,深支的大转子支经股方肌与下孖肌之间浅出到达大转子,供应范围约4×3cm。利用旋股内侧动脉深支及大转子支为血管蒂进行大转子骨瓣移位,是修复股骨颈骨折的一种简易手术新方案。
Anatomy of the greater trochanter was observed on 40 specimens. The posterior part of the greater trochanter produces a deep branch of the medial femoral artery of the spinous branch. The greater trochanter branch of the deep branch reaches the greater trochanter through the shallow between the femoral and hypogastric muscles. The supply range is about 4 × 3 cm. The use of the deep branches of the medial femoral artery and the greater trochanter pedicle graft for the greater trochanter bone flap displacement is a simple surgical repair femoral neck new program.
