2017 AAOS Annual Meeting: Unlocked versus Dynamic and Static Distal Locked Femoral Nails in Stable Intertrochanteric Femoral Fractures: A Prospective Randomized Multicentric Study

240 patients undergoing intramedullary nail fixation of stable intertrochanteric femoral fractures were randomized to three groups; static locking, dynamic locking, or no locking. Patients were assessed for intraoperative outcomes, and clinical outcome measure over 12-month follow-up. Patients in the unlocked groups had significantly decreased operative time, blood loss, total fluoroscopy time, and incision length compared to the other two groups. Additionally, patients in the unlocked group had a significantly shorter time to union compared to the other two groups. There were no significant differences in SF-12, Barthel Index scores, or complications between the three groups.
