INTERTAN

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

  • Lower risk of implant failure and reoperation 4-5,8,13-15, 17,22,24-26, 28
  • Faster time to fracture union 5,8-9, 17,20,22-24,26,28
  • High return to pre-fracture status 5,8,12,17,22,24,26,28

TSF

A systematic review of the literature found:

  • Consolidation rates for children in all three indications were 100%.
  • Consolidation rates for adults with acute trauma, non/malunion, and deformities were 99.2%, 100%, and 100%, respectively.
  • The majority of complications in adults (64.1%) and children (68.5%) were considered grade I, and did not require operative strategies to address.
