VERILAST Technology for Hips

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
  • Biocompatible solution for metal sensitive patients
  • 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.

Design

VERILAST Hips Design Information

  • A biocompatible solution for metal sensitive patients.
  • OXINIUM heads contains <0.0035% for Nickel, <0.002% for Cobalt" and <0.01% for Chromium; which are the most allergen causing metal elements for humans.
    • Due to its lubricious nature, OXINIUM will wear like a ceramic head.
    • OXINIUM on XLPE has been shown to produce fewer polyethylene particles than CoCr on XLPE even under active conditions.
    • Less wear particles means less ostyletic potential.
    • Fully supported poly
    • Mechanical strength less critical
    • Higher radiation dose = improved bearing wear
    • Under special heating conditions it grabs oxygen from the environment.
    • Oxygen mixes with Zirconium to form Zirconium Dioxide.
    • Zirconium Dioxide is a true monoclinic (no phase change) ceramic.
    • OXINIUM has a ceramic surface that is integral to the underlying metal.
    • The ceramic is not a coating. It can bend and flex with the metal.
    • OXINIUM is known as a functionally graded material meaning it starts as one material and under special conditions transforms to a different material.
    • The ceramic surface is 5-7 microns thick with an underlying hard material known as the oxygen enriched zone. Below this is the Zirconium-Niobium alloy.
  • A reduced risk of osteolytic potential Smith & Nephew's XLPE for Hips = 10 MRad irradiated 1050 polyethylene

What is an OXINIUM femoral head?

OXINIUM is made from Zirconium with 0.5% Niobium metal alloy.
