OASYS Midline Occiput Plate – Stryker initiated a recall of its OASYS spine plate system on May 30, 2013. This affects only products manufactured between April 23, 2010, and Feb. 12, 2013. Stryker received reports indicating post-operative fracture of the pin that connects the tulip head to the plate body. This may cause serious adverse health consequences, including blood loss, nerve injury, and the need for revision surgery to replace the fractured implant. On June 20, 2013, Stryker notified spinal implant surgeons recommending routine clinical and radiographic post-operative evaluation for patients with the implant.
