Do we need to use the largest possible size of the Proximal Femoral Nail Anti-rotation (PFNA) in well-reduced intertrochanteric fracture? A study of distal PFNA intramedullary canal occupying ratio (ICOR).
ICOR was not a significant predictor of fracture healing or fixation stability in intertrochanteric fracture treatment using proximal femoral nail anti-rotation surgery, and in uncertain cases regarding nail size, using a smaller nail was not linked to inferior radiographic or fixation-related outcomes.
