Im not 100% sure what I have in me. I have papers from the surgeon that he gave me a month before surgery (2 years ago) that said he would use DePuy. I also have papers that say Richard Birmingham and after some looking around online that is made by Smith and Nephew. I did give all of my info and medical records to a law firm and yesterday they sent a letter back (with my records) stating they could not pick up my case. They did not say why. I know in other countrys they are pushing for a recall of all metal on metal inplants and now the FDA is starting to look at that also. Back to square one! Again
