Core Tip
Core Tip: This study modeled different internal fixation methods for unstable proximal femoral fractures. Finite element analysis of the femur model was established and three intertrochanteric fracture models were simulated. For medial defects, intramedullary fixation would allow early low-intensity rehabilitation exercise, and integrated dual-screw fixation (ITN) rather than proximal femoral anti-rotation intramedullary nail reduces the risk of varus and cut-out; for lateral wall defects or weakness, intramedullary fixation allows higher-intensity rehabilitation exercise, and ITN reduces the risk of varus. For both medial and lateral defects, intramedullary fixation alone will not allow early functional exercise but locating lateral or medial reconstruction will.
