The proximal femoral nail (PFN) is an osteosynthetic implant designed to treat proximal femoral fractures[1] in the trochanter area with a closed intramedullary fixation method.

Similar to the gamma nail[2] the proximal femoral nail consists of a funnel-shaped intramedullary nail with slight bending to reflect proximal femoral diaphyseal trochanteric morphology. But different to the gamma nail, the proximal femoral nail features two proximal openings, a larger one further distally for a large femoral neck lag screw and a smaller one immediately above for a smaller anti-rotation screw/pin. There are small holes at the distal end of the nail for locking screws 1.

The proximal femoral nail comes also in different lengths with a version reaching caudally up to the distal femoral metaphysis. Longer nails are designed to treat low and extended subtrochanteric or combined trochanteric...
