Comparative Study of the Clinico-Radiological Outcomes of Fixation of Unstable Intertrochanteric Fractures with Standard Proximal Femoral Nail (PFN) and Proximal Femoral Nail Antirotation for Asia (PFNA2)

Introduction: Intertrochanteric fractures are common in elderly individuals with osteoporosis, where surgical fixation is crucial for reducing complications and promoting early mobilization. Proximal femoral nails (PFN) have been widely used for unstable intertrochanteric fractures, but complications such as screw cut-out and rotational instability persist. The PFNA2, featuring a helical blade, has been developed to improve fixation in osteoporotic bone by enhancing stability.
