Dual Mobility™

A proven concept for more than 35 years

Optimised hydrid liner

There is not just one direction in dislocation. With Trinity Dual Mobility it is possible to orientate the liner to get maximum coverage where required


Advanced polyethylene material, ECiMa

The ECiMa insert is one of the most advanced polyethylene of its kind, providing high performance


Eccentricity mechanism

The self centring mechanism is designed to avoid premature impingement and wear


Extraction as easy as insertion

Liner extraction can be difficult  but with Trinity Dual Mobility extraction is as easy as insertion thanks to the engineered taper and feature added in the liner


Cup preserving

If dislocation occurs with a previous ceramic or polyethylene liner, then just replace the bearing with the Dual Mobility system


A gold standard dual mobility cup designed to decrease the risk of dislocation

Standard motion covered by the small articulation (metallic or Biolox® delta)

Extreme motion covered by the large articulation (PE liner)


Anti-dislocation features

  • 3mm cylindrical extension of the hemisphere to increase jump distance and create an artificial wall
  • Self-positioning insert reducing stem neck impingement
  • PE liner chamfering to increase small articulation range of motion


Full range from primary to revision

  • Cementless or cemented range
  • Flanges and hook options available
  • Reinforcement ring dedicated to cemented version
  • MIS instruments available
