Recent studies indicate that females demonstrate an increased risk of experiencing adverse local tissue reactions, aseptic loosening, and revision after primary metal-on-metal hip resurfacing arthroplasty compared with males; the underlying biological mechanisms responsible for sex discrepancies in implant failure remain unclear. In addition to anatomical and biomechanical sex differences, there may be inherent immunological disparities that predispose females to more aggressive adaptive immune reactivity to implant … Read the rest
September 15, 2016 – First, I want to correct that I had my last ceramic and titanium bilateral hip revisions (to a failed bilateral Birmingham Hip Resurfacing) completed in November 2014 – not Nov 2105.
Secondly, after an almost 2 year recovery, I can most happily report that both hips AND knees do not hurt!! At most, my hips get stiff after prolonged use and … Read the rest

Metal Ions Questions & Answers Original information from McMinn Center Website below:
Earlier in 2011, the McMinn Centre team travelled to a meeting in Arizona and answered several questions about Metal-on-Metal (MoM) implants and issues to do with metal ions. The questions were posted by BHR users. For the benefit of the entire Hip Resurfacing community, the answers to those questions are provided below.
Patients concerned about the recent, … Read the rest
|Peter Kay Response to Metal Ion Level Test for MOM in UK after FDA update 1/2013 I think overall, from the U.K. perspective, metal-on-metal has been a real problem. (For) most surgeons in the United Kingdom, our usage of metal-on-metal hip replacements has dwindled to almost nothing because we cannot really find any advantage. The patients do not do any better in terms of function. There is some evidence the|
Article by Patricia Walter and Hip Resurfacing Surgeons
Patients and prospective patients are always concerned about the complications that could occur after a hip resurfacing surgery. The typical problems include femur neck fractures, dislocations, loose acetabular cups, improperly positioned acetabular cups, high metal ions, infections, pseudotumors, ALVAL and metalosis.
There has been a lot of discussion among patients on discussion groups about the high metal ion issue and pseudotumors. I … Read the rest

Occasional reports of joint replacement implant failure because of an apparent allergy to one of the metals in the device have appeared in the orthopedic literature ever since metal implants were used. (1-3) It is now recognized that a small number of patients will suffer from a form of allergy or
