In femoral intertrochanteric fractures, poor incision positioning may result in inaccurate intramedullary nail placement direction, which increases the difficulty of reduction and thus the size and number of incisions. Repeated intraoperative fluoroscopy not only increases the radiation exposure of the surgeon but also affects the operative outcomes. This technical note proposes a method of identifying incision positioning preoperatively using the "3-2-1" body surface localization method. This auxiliary positioning technique uses a body surface locator and the lower limb force axis. It can predict the incisions for the needle insertion point, spiral blade, and locking nails, create minimally invasive incisions, avoid incorrect incision position, facilitate accurate intraoperative intramedullary nail placement, reduce the incision size, intraoperative bleeding, and radiation exposure, and improve surgical efficiency and reduction quality.
在股骨转子间骨折中，切口定位不佳可能导致髓内钉置入方向不准确，增加复位难度，进而增加切口大小和数量。术中反复透视不仅增加术者的辐射暴露，还会影响手术效果。本技术说明提出一种术前使用“3-2-1”体表定位法确定切口定位的方法。这种辅助定位技术利用体表定位器和下肢力轴。它可以预测针插入点、螺旋刀片和锁定钉的切口，创建微创切口，避免切口位置错误，便于术中准确置入髓内钉，减小切口大小、术中出血和辐射暴露，并提高手术效率和复位质量。
