We use a straightforward technique for insertion of proximal interlocking screw fixation during retrograde intramedullary nailing of the femur utilizing a common 3 cc syringe as a radiolucent soft tissue protector. Following insertion of the implant and distal interlock insertion, the distal Luer-Lok tip of a 3 cc syringe is cut off to create a hollow tube. Once the correct location of the proximal locking holes is confirmed fluoroscopically, the syringe is inserted through the incision into the soft tissue over the long drill sleeve and trochar. The inner drill guide and trochar is then removed, leaving only the syringe. Through this syringe, the proximal interlocking hole is drilled and measured, and the screw is inserted. The syringe establishes a safe pathway for passage of instrumentation, mitigating damage to the surrounding soft tissues, and allowing for unobstructed fluoroscopic visualization throughout insertion of the locking screws. This technique is safe, inexpensive and reproducible; utilizing common equipment available in most operative settings.
我们采用一种简单的技术，在股骨逆行髓内钉固定过程中插入近端交锁螺钉，利用一个普通的3毫升注射器作为射线可透过的软组织保护器。在植入物插入和远端交锁插入后，将3毫升注射器的远端鲁尔锁接头切断，制成一个空心管。一旦通过荧光透视确认近端锁孔的正确位置，将注射器通过切口插入长钻套和套管针上方的软组织中。然后取出内部钻导器和套管针，仅留下注射器。通过该注射器，对近端交锁孔进行钻孔和测量，然后插入螺钉。注射器为器械通过建立了一条安全通道，减轻了对周围软组织的损伤，并在整个锁定螺钉插入过程中实现了无阻碍的荧光透视可视化。该技术安全、廉价且可重复；使用大多数手术环境中都有的常见设备。
