VERILAST Hip Technology

Product Information

What is VERILAST Technology for Hips from Smith & Nephew?

VERILAST Technology is a combination of our proprietary OXINIUM heads and a highly cross-linked polyethylene (XLPE) liner.

Hip implants that offer VERILAST options:

What are the features of VERILAST?

As an orthopaedic surgeon, you have a variety of options when choosing a hip implant best suited to your patients. However, you also deal with an unfortunate list of tradeoffs with most bearing couples. Then there's VERILAST Technology for Hips. The coupling of OXINIUM material on XLPE is a technology that eliminates the concerns faced with other bearing combinations.

  • No risk of ceramic type fracture, chipping or squeaking
  • Less polyethylene wear debris compared to standard cobalt chrome heads

Combine the XLPE liners with our acetabular cup options to get: 

  • Flush seating liners to reduce impingement chances and increase ROM.
  • Axial locking mechanism located lower in the shell where the poly is thicker and stresses can be distributed better.
  • Ultracongruent shell to fully support the poly for better stress distribution.
  • Large antirotation tabs for rotational stability.
