TRIGEN INTERTAN Intertrochanteric Antegrade Nail

Intertrochanteric Antegrade Nail



Your patients can enjoy life after hip fracture

The evidence is in!  Based on data from more than two-dozen published studies, the TRIGEN INTERTAN Intertrochanteric Antegrade Nail allows femur (hip) fracture patients to experience:

  • Lower risk of implant failure and non-union6,7,8,9,10,11,12,13,14,15
  • Reduced postoperative pain9,10,11,13,14,15
  • Faster time to fracture union9,11,12,13,19,23,24,25,26,27,28,29
  • Proven high return to pre-fracture status6,13,19,23


Features and Benefits

  • Maintain compression and eliminate Z-effect
  • Intertrochanteric rotational stability
  • Control rotation during reduction
  • Eliminate medial migration
  • Prevent periprosthetic fractures
