In some cases of the femoral neck fracture, the rotation of the head needs to be prevented. This is ensured by a double neck screw. The combined use of the two neck screws provides an increased strength for the system. The more distal, thicker neck screw is able to compress the fracture.
Design of the implants
The proximal femoral nails are available in short, solid or long, cannulated versions.The distal end can be fixed by two locking screws, dynamization of the fracture can also be ensured.
