Well put Boomer, totally agree. Don't worry Hoyt. Take a look at the links Pat posted. More than likely you are in the 96% to 98% range for success for 15 years or more. You might be a worrier anyway, but I don't think the benzodiazapenes and narcotics you've been exposed to for the surgery and early recovery, helped. Yes, most of it's probably gone, but there may be some residual effects for a week or so.
The BHR has the 20 yr olds in McMinn's data set as Pat points out. I believe that even some of the other devices like the Cormet are pushing 15 years, not sure about the Conserve but it's also got an excellent track record. There were three THR groups that had large head metal on metal (CoCr alloy just like our devices), the Mckeer-Farrer, Stanmore, and Ring installed in the 70s? Anyway, some of the THRs were successful to close to 40 years. McMinn studied these groups and the design when designing the BHR. I could not find a percent failure in these groups in McMinn's book. The point that McMinn makes in his book, is that if there is no reason for metals to be generated from wear, like from poor angles, then it is extremely unlikely that metallosis will occur. In addition to Pat's links, you might look up a paper by Pritchett on his website (Orthopedics International) about metallosis. It's not overloaded with medical terminology and is a pretty good read.
Also, keep in mind that much of the dust-up regarding MoM and metallosis with Hip Resurfacing has to do with the ASR lawsuit (2010). I think media and lawyers are still trying to get a piece of the action by going on and on about metalloisis with MoM HRs when the datasets from many of the best surgeons and national registries are showing excellent results.
On the other hand, you could also just forget about all of this crap and do what Boomer said, plan for fun and enjoyment of a new life.
