Despite the fact that the extended nail could shield additional of your femoral shaft, the bone could be at threat of fracture distally about the end of your nail above the knee.

Stable fractures ordinarily have 2 or three parts with intact medial and lateral buttresses and really should be treated with sliding hip screw fixation. The lateral buttress makes it possible for for any firm end point for the sliding from the screw.86 The sliding hip screw performs by having a firmly anchored screw in the femoral head.

The important aspect inside the success in the hip screw would be the placement in the screw within the femoral head. The screw need to be as deep as you can and centered together with the head.
