股骨近端不稳定骨折的头颅髓内钉治疗得到了广泛的应用。尤其是老年骨质疏松性骨折。进入有两个起点,即转子尖端入口和梨状窝入口,两者都有优点和缺点,大转子的尖端似乎不是转子进入钉的理想起点,这项研究提出了山麓切入点作为一个可重复的,在技术上可行的切入点,以克服两个标准起点的缺点,术中清晰的透视标志可以很容易地执行,并导致合适的指甲位置,无术中并发症。
Cephalomedullary nailing for unstable proximal femoral fractures is widely utilized, especially for geriatric osteoporotic fractures. There are two starting points for entry, namely trochanteric tip entry and pyriformis fossa entry, both have advantages and disadvantages, the tip of the greater trochanter seems that it is not the ideal starting point for trochanteric entry nails, the study presents the foothill entry point as a reproducible, technically feasible entry point to overcome the shortcoming of both standard starting points, and it could be easy executed with clear intraoperative fluoroscopic landmarks and lead to appropriate nail position without intraoperative complications.
