Proximal Femoral Nail Antirotation (PFNA): Technique, Indications & Instrumentation

 

The Proximal Femoral Nail Antirotation (PFNA) is a modern implant designed for treating hip fractures, particularly intertrochanteric and subtrochanteric fractures in elderly patients with weak bones. Unlike standard nails, PFNA features a helical blade that compacts bone as it enters, providing superior stability and resistance against rotational forces. The procedure is minimally invasive, involving a small incision at the greater trochanter, nail insertion into the femoral canal, placement of the helical blade, and distal locking with screws under fluoroscopic guidance. PFNA enables strong fixation, early mobilization, reduced complications, and faster recovery, making it a preferred choice in complex fractures.
