Hip fractures are becoming a more prevalent issue worldwide, leading to profound morbidity, and in some cases, mortality. Currently the most common method of surgical treatment includes the use of a sliding hip screw over a Gamma intramedullary nail, but there is conflicting evidence regarding which device has a lower revision surgery rate and complication rate. Recent improvements in implant design of the Gamma3 nail, demonstrating decreased rates of femoral shaft fractures and improved function, provide compelling rationale for the conduct of a large, definitive trial.

This trial is a definitive, multi-center, concealed randomized controlled trial. Surgeons will use one of the two surgical strategies in patients who have sustained a trochanteric fracture; the Gamma3 intramedullary nail or the sliding hip screw. Clinical assessments will occur at the time of hospital admission, post-surgery, 13 weeks, 26 weeks, 52 weeks, and 104 weeks.
