Thomas Gross MD 7/10/2021
Dr. Gross discusses the new ceramic on ceramic hip resurfacing devices and compares them to metal on metal hip resurfacing devises. His summary conclusion:
“I am also involved in CoC HRA development. If these become available in the US I will be involved in early trials. Avoiding the whole tiresome discussion of allergy/toxicity/metallosis would be nice. But if I needed surgery, I would personally choose the proven uncemented MoM HRA which … Read the rest

Response to Telegraph Article – News Feed Monday 3rd July 2017
In response to the recent Telegraph article, Mr McMinn would like to reassure all of his patients that nothing has changed in the outcomes of our hip resurfacing and total hip replacement patients. Our results do not show anything different, but the MHRA guidelines have changed, probably because of some reports of small diameter metal-on-metal total hip replacements. … Read the rest
Original MEDICAL DEVICE ALERT by UK MHRA 2017 Available Here
The Medicines and Healthcare products Regulatory Agency (MHRA) UK has called for longer-term monitoring of all patients fitted with metal-on-metal hip implants, as a precautionary measure, in an update to its original guidance issued in 2012.
“MHRA, in colsultation with its independent Metal-on-Metal Expert Advisory Group (MoM EAG), has continued to monitor the performance of MoM hip joint articulations for the occurrence of soft tissue … Read the rest
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 debris, i.e., metal sensitivity…

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 I can’t squat as easily. … Read the rest

Metal Ions Questions & Answers Original information from McMinn Center Website below:
http://www.mcminncentre.co.uk/metal-ions-questions-answers.html
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, negative ASR press coverage may … 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 patient’s reported pain levels are |
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 am not a doctor or … 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 hypersensitivity to constituents of the metal-on-metal bearings even in the absence of high wear or a known metal sensitivity (4-6). The histological features of … Read the rest

Jacobs, MD. “Metal allergy [with] orthopedic implants has been well documented in isolated cases,” Jacobs said during his presentation at the American Academy of Orthopaedic Surgeons 2012 Annual Meeting/Orthopaedics Research Society symposium. “The true prevalence is unknown.
