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.

The Stryker recall of the Rejuvenate and ABGII hip implants in July, 2012, left many implant recipients extremely concerned about their health and their future. After receiving FDA approval in 2008 and 2009, both models were marketed aggressively due to their new design which allowed surgeons the ability to fit the implants more precisely, according to the activity level and body size of the individual.
