TFN-ADVANCED™ Proximal Femoral Nailing System (TFNA)

The TFNA System is designed to advance the treatment of trochanteric fractures by providing surgical options that help to preserve bone in insertion area due to reduced critical width, improve anatomical fit1 and increase implant strength.2 It is designed to reduce the risk of cut-out,3,4 distal cortical impingement1 and nail breakage,2 which are common post-operative complications.5,6,7 Several clinical studies have published reporting favourable outcomes in cut-out resistance.8-10*
