VerSys Epoch FullCoat Hip System

Reducing stiffness… to address clinical issues.

The VerSys Epoch FullCoat Hip System is the first reduced stiffness stem specifically designed to address all patient femoral anatomies to minimize implant-related complications such as thigh pain, stress shielding, and leg lengthening.1,2  The innovative flexible composite stem closely mimics the bending stiffness of bone.

  • 75% less stiff than cobalt-chromium (CoCr) alloy stems and 50% less stiff than titanium alloy stems to address thigh pain and reduce the risk of stress shielding3
  • Extensively porous coated to provide both initial and long term implant stability4
