To evaluate the neurovascular structures at risk with the placement of anterior-posterior locking screws in the proximal femur.
Cadaveric study.
Anatomic relationships.
The femoral artery lies medial to the femur, and its branches cross the anterior femur more than four centimeters distal to the lesser trochanter. Branches of the femoral nerve cross the anterior femur proximal to the lesser trochanter and start four centimeters distal to the piriformis fossa.
Risks to the neurovascular structures during anterior-posterior locking in the proximal femur are diminished if locking is performed above the level of the lesser trochanter.
评估在股骨近端前后位置入锁定螺钉时面临风险的神经血管结构。
尸体研究。
解剖关系。
股动脉位于股骨内侧，其分支在小转子远端超过4厘米处穿过股骨前方。股神经分支在小转子近端穿过股骨前方，起自梨状肌窝远端4厘米处。
如果在小转子水平以上进行锁定，则股骨近端前后位锁定期间神经血管结构面临的风险会降低。
