although pfna and tfn nailing systems have been successfully used in the past, several clinical issues for improvement have been identified by surgeons and engineers. the tfn- advanced ( tfna) proximal femoral nailing system ( depuy synthes) is a cephalomedullary nail intended for the treatment of proximal femoral fractures. the tfn- advanced nailing system is a part of the advanced nailing system from depuy synthes and has features that allow surgeons to address proximal femur fractures. 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 fit 1 and increase implant strength. tfn- advanced™ proximal femoral nailing system ( tfna) – screw only fi surgical technique 3 the ao principles of fracture management 1. 4 depuy synthes companies tfn– advanced proximal femoral nailing system ( tfna) surgical technique ao principles_ priciples_ 03. 2 it is designed to reduce the risk of cut- out, 3, 4 distal cortical impingement 1 and nail breakage, 2. the system includes: long nails – diameters: 9- 12, & 14 mm. specifi cally, the system is. berlin, heidelberg new york: springer 1991. lengths ranging from: 260 – 480 mm. se_ 793148 ac page 2 / 7 instructions for use tfna, 9 mm, long right left length ( mm) femoral neck angle 04. design evidence tfn- advanced™ proximal femoral nailing system ( tfna) rotational and static locking abstract the tfn- advanced™ proximal femoral nailing system ( tfna) features a pre- assembled locking mechanism within the nail to allow the intra- operative decision of rotational locking ( control the rotation of the helical blade or lag screw) or statically locking ( control the rotation and. position the image intensifier as for an ap view of the proximal femur. 919s 280 125° 04. tfn- advanced™ proximal femoral nailing system implants date: hospital: surgeon: procedure: case information ( eg, case id) : tfn- advancedtm system ( tfna), long nails, 9 mm distal pdf diameter, sterile right part #
