Trabecular Metal Material has 10% greater porosity than Regenerex 2,3 and demonstrated clinical history.1

  • Animal studies have indicated that this high porosity yields more extensive and rapid bone ingrowth than other tested porous materials.  Clinical and radiographic analyses of Trabecular Metal Components have shown statistically improved gap filling by bone and excellent stability.3-5
  • Trabecular Metal Material has a Microtextured surface topography. 1 Zimmer believes that the surface topography of Trabecular Metal Material also allows for excellent soft-tissue adhesion.  Trabecular Metal Material permits rapid ingrowth of vascularized soft tissue and attains soft-tissue attachment strengths greater than other materials.6  This science is backed by 10 years of clinical success.
