Hi Gerard, you've gotten a lot of good feedback supported by good data.
Some comments:
Now I’m not so sure?
My doctor was definitely steering my away from resurfacing and towards total replacement. The information I received from my Doctor in a nutshell:
1) ALL metal on metal hip implants are now considered problematic due to metal ion sensitivity? So not just the Depuey.
I heard this from two surgeons that I went to before I found my surgeon. It is an opinion not backed by data. The percentage of total problems caused by metal ion sensitivity is about 8 percent. So that means of all causes for revision as identified by the Australian registry, which is the most extensive study of both THRs and HRs available, 8% of those were caused by metal ion sensitivity.
That includes all procedures and devices, both the Depuy and Duron devices since recalled are in that study, yet the failure rate was still
8% of failures . The overall revision rate over the span of ten years was about 7 percent for all HRs. This included patients who may not have been good candidates, who did not follow proper procedures, whose surgeons had low experience, skills or capabilities.
So the failure rate due to metal sensitivity is 0.08 X 0.07 = 0.0056 or 0.56 percent over a ten year period. The rate of revision for HRs over a ten year period due to metal sensitivity is thus 1/2 of one percent. In the largest study available for us to use.
So I'm not sure where the problematic comes from. If you choose a good experienced surgeon, your odds go up dramatically, which I'm sure you will see if you get in touch with some of the better HR surgeons.
Another thing the study found is that once a surgeon does above 200 surgeries, their revision rate drops greatly. It just makes sense for a more demanding procedure that the surgeons that do many and do them often are more successful. You need committment for this to be a success.
2) The odds of returning to an active life style are about the same whether I have the resurfacing or the total replacement.
The odds are good for both if you have large head THRs. The smaller heads, as Tim has pointed out are restrictive in lifestyle, since you are at risk for dislocation that is not present with the larger head sizes.
I believe that HR is better for younger active people, since you keep more bone mass. In the case of a future THR revision, which we all face the possibility of, more bone mass will be present to support the procedure. Of course we all hope for no revision needed.
3) The problems associated with the total hip replacement are significantly less than with the resurfacing?
THR has its own issues. Especially for younger, more active people.
4) The number of Resurfacing procedures being performed has greatly dropped with the problems associated with metal sensitivity.
I think (this is just me, not Pat) that the issue has shaken the tree and removed the dilettantes. The people who are skilled, remain and thrive are the people committed and take pride in producing good results in their patients. It has been a backhanded advancement in that the people who "will do it if you insist" are out of the business. I'd prefer that they stay out, but it is also a byproduct that they will bad mouth the procedure.
I don't have any problem with good, fact based criticism. It is giving unsupported opinions to good people in need that irks me.
5) My body size (about 5’7”) is on the lower end for the socket (in a BHResurfacing procedure) and might cause a problem?
Smaller people do present a surgeon more issues in the overall scheme. As Tim pointed out, the size of the hip more than height is the challenge. That does not mean that smalller people are not successful, just that you need a skilled surgeon.
....
Are there other people out there hearing the same:
Resurfacing - Return to active life about 76% positive results.
-Ion (metal on metal) problems?
- Problems increasing and not fully understood yet??
Over a ten year period in the best accumulation of results, the amount of HRs that were not revised (one measure of success) was 93 percent. Revisions due to Ion problems were 0.5%.
Nothing is ever fully understood, but statistically I think we have a good measure here.
Total Replacement
- Return to active life about 75% positive results.
- Problems occurring in less than 5% (something like that??) and a greater track record.
I think this also doesn't give THR enough credit. Check the results from the Australian registry (don't have those at hand). There is a longer track record, only because HR has been around for less time.
It's like saying that cars are not a proven method of transportation since they have not been around as long as a horse and chariot.
THR and HR both provide good services for their proper targets. I have two HRs and have returned to a very active, happy life. Will I have problems in the future? Maybe. If so, I am ready for it, but I am in the place I expected now and would not give back the last two years for anything.
Any feedback would be much appreciated
Gerard - you are asking the right questions. Many of us faced the same reaction from some surgeons and went through anyways. Get more opinions, and definitely if you want good results from an HR, find another surgeon who is not reluctant.
You want a good, strong surgeon who has done many and does many every week. There are a good number of those, but you have to be willing to find them.
Good luck.
