Introducing the New E1Ringloc-x+3mm liners


The Exceed ABT E1 Ringloc-x +3mm Liners offer a unique opportunity to provide increased dislocation resistance with the use of large femoral heads in smaller acetabular shells.

E1 Antioxidant Infused Technology prevents oxidative degradation of the polyethylene, and offers an alternative ultra low wear soft bearing option for active patients.

The tri-bearing Exceed ABT acetabular platform addresses patients and practice needs by combining technological development in large diameter bearings with clinically proven fixation methods.

  • Utra-low wear bearing: E1 offers high mechanical strength1,2 and true oxidative resistance3
     
  • Maximised bearing diameter for greater implant stability and range of motion: The built-in offset of the E1Ringloc-x+3mm liners helps maximise the bearing diameters without compromising the minimum polyethylene thickness and mechanical properties.
    - A 32mm head can be used in a 46mm cup and above.
    - A 36mm head can be used in a 50mm cup and above.
    - A 40mm head can be used in a 54mm cup and above.
     
  • Secure Fixation Method


The Ringloc locking technology achieves maximum push-out, lever-out strength with lowest micro-motion of independently tested competitive systems.4,5,6,7 Ringloc is a durable clinically proven technology with 12 year follow-up.8
