Among those with a recalled Stryker Rejuvenate or ABGII hip implant device, Stryker cobalt toxicity is a very real concern. Even though the Rejuvenate and ABGII have a smaller metal surface area, corrosion and the release of metal ions can occur at the metal neck juncture as well as underneath the small metal trunnions located on either end of the neck piece.

In April, 2012, Stryker Orthopedics issued an Urgent Field Safety Notice to hospitals and surgeons, warning them of the potential risks of the Rejuvenate and ABGII hip implants, including symptoms of Stryker cobalt toxicity.
