Objectives: To compare the results between a sliding compression hip screw and an intramedullary nail in the treatment of pertrochanteric fractures.
Design: Prospective computer-generated randomization of 206 patients into two study groups: those treated by sliding compression hip screw (Group 1; n = 106) and those treated by intramedullary nailing (Group 2; n = 100).
Setting: University Level I trauma center.
Patients: All patients over the age of fifty-five years presenting with fractures of the trochanteric region caused by a low-energy injury, classified as AO/OTA Type 31-A1 and A2.
Intervention: Treatment with a sliding compression hip screw (Dynamic Hip Screw; Synthes-Stratec, Oberdorf, Switzerland) or an intramedullary nail (Proximal Femoral Nail; Synthes-Stratec, Oberdorf, Switzerland).
Main outcome measurements: Intraoperative: operative and fluoroscopy times, the difficulty of the operation, intraoperative complications, and blood loss. Radiologic: fracture healing and failure of fixation. Clinical: pain, social functioning score, and mobility score.
Results: The minimum follow-up was one year. We did not find any statistically significant difference, intraoperatively, radiologically, or clinically, between the two groups of patients.
Conclusions: There is no advantage to an intramedullary nail versus a sliding compression hip screw for low-energy pertrochanteric fractures AO/OTA 31-A1 and A2, specifically with its increased cost and lack of evidence to show decreased complications or improved patient outcome.
