Clinical Support

10 years of clinical data shows that Epoch Technology helps reduce the complications associated with modulus mismatch between the stem and the bone.5

Radiographic and DEXA analyses show more than a 50 percent reduction in bone mineral density loss with the Epoch Stem compared to beaded Co-Cr alloy implants.1

Clinically proven Fiber Metal offers an extensive surface for bone ingrowth to increase long-term mechanical stability. In a multicenter clinical study involving 72 patients (mean follow-up of 10 years)3:

  • None failed to achieve bone ingrowth
  • None have required revision
