How to insert the femoral nail？

Although the choice of internal fixation for peritrochanteric fractures is still controversial, the use of femoral nails has been accepted by most orthopedic surgeons. Nevertheless, complications caused by femoral nails are not uncommon, and the most common are iatrogenic femoral fractures and proximal lag screw cuts.
In addition, the emergence of a new generation of internal fixation devices has also significantly reduced the circumferential stress of the proximal femur, and made the anterior femoral arch and the radius of curvature of the femoral nail better match. Compared with this, the cutting out of lag screws is more related to surgical technical errors.
After the femoral nail is inserted, the hip joint fluoroscopy is performed to determine the depth of the femoral nail insertion. The guide pin of the lag screw can be located in the center or slightly lower position of the femoral head, and then the image intensifier can be rotated to the standard lateral position. , That is, parallel to the operating table, the extramedullary guide connected to the femoral nail rotates beyond the perspective range, and the affected hip is now in the center of the image field of view.
Rotate the image intensifier upward until the femoral nail is exactly in the center of the femoral head. This angle represents the angle at which the lag screw is driven from the femoral nail into the femoral head. At this time, the C arm is locked at this angle. Rotate the extramedullary guide until it is parallel to the projection angle of the image intensifier. At this time, it can be seen that the femoral nail is located in the middle of the shadow of the guide and passes through the center of the femoral head. If the lag screw driven in this position is exactly aligned with the center of the femoral head. Then insert the sleeve of the proximal lag screw, check again that all components are installed correctly, and make sure that the guide and the image intensifier are parallel, drive the guide needle through the track of the guide, and follow the center of rotation of the femoral head to the subchondral bone. Finally, rotate the image intensifier back to the normal position (perpendicular to the previous position) to confirm the depth of the guide pin. At this point, the nail path of the lag screw has been determined, and the subsequent steps can be continued in accordance with the standard operation.
