| Abstract Background: Young adults typically sustain femoral neck fractures (Pauwels type III classification) as a result of high-energy trauma, and these fractures are commonly observed in conjunction with other injuries. Taking into account the debates around the best fixation for this fracture. Aim: To assess the trochantric lag screw's clinical therapeutic efficacy in fixing femur fractures. Methods: We selected one hundred consecutive patients with Pauwels' type III femoral neck fractures for this investigation. Results: The average age of the cases under study was 53.29 (±7.81 SD), with a range of 36 to 65. Of the cases under study, 43 (43%) were female and 57 (57%) were male. According to injury mechanism, there were 27(27%) injuries during a car accident, 59(59%) due to a fall, and 14(14%) during a motor accident and according to fracture 56(56%) had fracture in the right side and 44(44%) had fracture in the left side. The mean operation time was 117.48(±11.8 SD) with range(95-138) minutes, the mean intraoperative bleeding was 21.14(±3.34 SD) with range(15-27) ml. Among the studied cases, 94(94%) healed and 6(6%). The mean Harris score was 81.51 (±5.28 SD) with a range of 66-90, and 2 patients (2% of the total) had osteonecrosis of the femoral head. Conclusion: When fixing femoral neck fractures that are oriented vertically, a trochanteric lag screw construct significantly improves mechanical performance. | ||
