You would think that medical devices implanted inside your body would be some of the most highly-tested products in the world. Not so, though, for hip implants made by the Stryker company, who began selling its hips without going through clinical trials first.
Stryker claimed its hips were similar to DePuy’s metal on metal hips that were already for sale. The fault in this logic, if you can call it that, is that DePuy’s hip implants are the ones having problems with fretting and corrosion of the metal, which causes pain and swelling. This defect may even lead to metalosis – metal toxicity in the blood stream caused by metal ions and shavings from the implant itself. This, despite the fact that the industry has known for some time that as much as 40% of metal-on-metal hip implants would fail.
What does this mean to you:
Someone with a recalled hip implant probably does not know the make or model they have. If an implant patient continues to have, or suddenly develops, pain or swelling around their hip implant, they should check with their surgeon right away.
