Interesting article. Thanks
I think they should be careful when they say that HR is only appropriate for a small portion of the THA world (both HR and THR). It was something like that in the article. The key to that argument is to present the total THA population and then show how many of them are HRs and how many are THRs. Indeed there is an aging population that have a local ortho clinics nearby with THR surgeons that crank them out, and the patient has essentially no knowledge of the potential to go with an HR, so they get the THR. ALso as pointed out in the article, the increased bone density in the femoral head with some new stresses, may actual increase the strengh of the neck in an aging person who might have decrease bone density.
I still think everyone looking into THA, should consider HR no matter what. Doesn't hurt to look and ask questions.
Good article.
