Verilast for Hips

Lowest Revision Rate Among all Hip Replacement Materials

A common issue with hip replacements is what surgeons refer to as "wear." As the new surfaces of the implant rub together—up to 2 million times per year in active adults—friction occurs. This leads to scratches which make tiny fragments of plastic and metal material rub off, thus wearing down the implant.

This effect—not unlike the action of a fingernail file—is a main reason why hip implants can "fail," and why a patient may undergo repeat surgery years after the original procedure.

At Smith & Nephew, we worked for more than a decade developing a new technology that addresses this problem for the tens of thousands of young, active patients who need a hip implant that can support their adventurous spirit. In 2003, we introduced our exclusive OXINIUM oxidized zirconium for hip replacements.

OXINIUM material—a patented metal alloy and ceramic hybrid—has proven to be a superior metal for use in hip implants due to its hardness, smoothness and resistance to scratching and abrasion. The superior strength results in significantly less wear than cobalt chrome (historically the material of choice in hip implants).

Oxinium + XLPE = Verilast

Features and Benefits

  • No risk of ceramic type fracture, chipping or squeaking (Fracture)

  • Hypoallergenic solution for metal sensitive patients (Metal Sensitivity)

  • Less polyethylene wear debris compared to standard cobalt chrome heads (Osteolysis)
