Metal-on-metal bearings in hip resurfacing arthroplasty have been associated with prolonged periods of elevated metal ion circulation in the bloodstream.  Specific ions, such as chromium and cobalt are known to be particularly threatening to the general health of the patient, often times leading to symptoms associated with metal toxicity.  A recent study focused on the …

Metal-on-metal (MOM) total hip replacement has been a commonly used approach to hip repair, and with this surgery the risk of adverse effects is always present.  These effects include osteolysis, or bone-decay, as well as toxicity due to the metals that release ions into the body.  Recently, ceramic-on-ceramic total hip replacement surgery has been considered…

Metal-on-metal hip replacement (MOM) was introduced in total hip replacement to avoid complications such as osteolysis, the process where bone marrow is not produced, causing weakness in joints and bone structure to occur, a phenomenon often times found in patients with conventional ultra-high molecular weight polyethylene bearings.  This ailment is oftentimes only symptomatic in giving…

Many factors affect the blood metal ion levels of patients after metal-on-metal hip arthroplasty.  While certain ions have found to cause a range of adverse events, others, such as chromium and cobalt have been found to be carcinogenic.  A current study by AlisterJ. Hart et al. focused on the main surgically-adjustable variable, the amount of…

A recent study conducted by Wolf-Christoph Witzleb et al. focused on the implications of the metal ions released through the expected corrosion that occurs after a metal-on-metal hip replacement or hip resurfacing.  Two of these metal ions, cobalt and chromium are known to have carcinogenic and mutagenic effects in patients with metal-on-metal hips, leading to…

A recent study in Symposium posed the question of whether metal ions released from arthroplasty reach levels comparable to that of workers in heavy metal industries.  The metal ions are most commonly cleared through urine, meaning that high enough levels can lead to renal damage.  The study, published by Dr. Massimo Corradi et al. (2011)…

This is from 02/18, but I forgot to post it back then.  Not sure what ramifications, if any, this will have for the various DePuy and Striker hip replacement lawsuits.  I’m certainly interested in speaking to anyone with a problem with their replacement hip regardless of gender.

CHICAGO — Hip replacements are slightly more likely
