TRIGEN INTERTAN Claims v2 thumbnail


The benefits of the TRIGEN INTERTAN system – lower risk of implant failure and non-union, reduced postoperative pain, faster time to fracture union, and a proven high return to pre-fracture status – can help you achieve better outcomes more efficiently.




TRIGEN INTERTAN Bone and Joint outcome research paper

Bone and Joint Outcome Whitepaper

A systematic literature review and meta-analysis of the literaturefound that, compared to those treated with comparator devices theTRIGEN INTERTAN nail results in:

• A 69% reduction in implant failures (p=0.001)

• A 73% reduction in non-unions (p=0.01)

• A 54% reduction in patients complaining of hip andthigh pain (p=0.003)

• Improvement in health related quality of life,as measured by the SF-36 (physical health) score,in a single study (p=0.002)





TAYLOR SPATIAL FRAME is a computer-assisted external circular fixator with 20 years of clinical data.

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.
