A PFN - Antirotator Proximal Femur Nail

A-PFN is a proximal femoral intramedullary nail system developed by TST that provides rotational stability in femoral head fractures.

125° collodiaphyseal angle

Compression up to 7 mm

static and dynamic distal locking options and distal slot design


  • It has high strength and is made from biocompatible Ti6Al4V Eli F136 raw material.
  • Because of the cannulated proximal lag screw, it provides compression up to 7 mm.
  • The anti-rotation blade eliminates the “Z effect” effect and prevents rotation of the femoral head thanks to the blade groove.
  • It has a distal slot design that eases nail application and reduces stress focusing by allowing stretching.
  • Provides static and dynamic distal locking options.
  • The short load arm design reduces the tensile forces on the implant and the risk of implant failure.



  • Proximal femur upper-end fractures;
    • Pertrochanteric fractures,
    • Intertrochanteric fractures,
    • Subtrochanteric fractures.
