The purpose of this study is to look at the effect of locking or not locking a set screw when placing a rod and screws device in the thigh bone and hip to fix hip fractures. The set screw is an extra screw in the device that will not allow the screw that goes into the ball of the ball and socket joint in the hip to slide at all in relation to the rod in the thigh bone, which it goes through. It is not known whether it is better to lock the set screw (not allow sliding of the hip screw) or leave it unlocked (allow sliding of the hip screw). Participants in this study are patients with intertrochanteric hip fractures receiving standard care for this injury (lining the fracture up in a normal position and inserting a rod in the thigh bone with a screw that goes through the rod into the ball of the ball and socket of the hip). Patients who consent to participate will be randomized to one of two arms : 1. Set screw is unlocked or 2. Set screw is locked. Participants will all get standard postoperative care and standard postoperative xrays.
