• Arkansas Surgeon Monitoring Stryker Metal Hips

  • Arkansas orthopedic surgeon, Dr. Win Moore III, was shocked when he received a one-page letter from Stryker Corp. in 2012 announcing a problem with its metal-on-metal hip replacement systems. With more than 20 years of experience, the surgeon at Baxter Regional Bone and Joint Clinic, has performed hundreds of surgeries.

    Nearly One-Fourth of Surgeon’s Patients Receiving Stryker Metal-On-Metal Hip Implants Needed Revision Surgery

    The medical device recall referenced two products - the Rejuvenate and AGB II modular-neck hip stems. Moore and his staff identified 59 patients affected by the Stryker recall. Of those, 14 patients required revision surgery.

    The surgeon reportedly was extremely concerned about the criteria for determining when a hip implant required removal. According to Moore, Stryker was not helpful.

    One problem with the devices, the orthopedic surgeon learned, involves "fretting," meaning that tiny particles of cobalt and chromium flake off from the metal-on-metal joint and drift into nearby tissue. The body then attacks the metal debris, resulting in inflammation, pain and other issues.

    When harmful cobalt levels reach a certain point, the metal-on-metal hip device has to be removed and replaced. And patients have to be monitored for life to detect whether the cobalt levels in the blood become dangerous at some point in the future. In fact, some patients feel fine even when their chromium or cobalt levels have become unacceptable. That’s why monitoring is so important.
