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*
Features & Benefits
1.0 m Radius of Curvature
May better fit the femoral anatomy.1
LATERAL RELIEF CUTTM & Small Proximal Diameter
May help preserve bone in the insertion area due to reduced critical width.
TIMo Titanium Alloy & Bump Cut Design
May provide improved fatigue strength when compared with existing nails of similar size.2
Perforated Blade & Screw Design
Allows for optional decision to insert PMMA cement around the implant in the femoral head.
May improve efficiency and ease-of-use for surgeons and OR staff through design.
