Key Points

  • To evaluate how changes in PFNA nail position affect bone healing and femoral head varus in intertrochanteric fractures.
  • Clinical evaluation of stable intertrochanteric fractures
  • Biomechanical assessment of fixation stability and stress distribution
  • Analysis of nail position adjustments and surgical outcomes
  • PFNA nail position demonstrated minimal impact on fixation stability
  • Stress distribution around the femoral head was largely unaffected
  • Intraoperative adjustments of the guidewire are deemed unnecessary

Abstract

The position of the PFNA nail has only a minimal impact on fixation stability and stress distribution around the femoral head in stable intertrochanteric fractures. Therefore, intraoperative guidewire adjustments are unnecessary when treating such stable fractures with PFNA.
