Total Hip Replacement (THR) is generally a highly successful treatment for late stage hip joint diseases and wear, however, wear continues to be one of the major causes of metal-on-metal THR's failure. Hip replacements typically experience a two-stage wear; a higher initial wear rate in the...
A number of metal-on-metal (MoM) hip replacement devices have been recently withdrawn from the market due to concerns at reported failure rates. Higher failure rates have been reported for modular large head metal-on-metal (LHMoM) hip replacements when compared to the same bearing used as a...
Hello. My name is Scott Ball. I am an orthopaedic surgeon at the University of California San Diego Medical Center. I specialize in joint replacement surgery. I am here today to discuss metal-against-metal hip replacements. Recently, an implant was recalled from the market and another implant ...

Metal-on-metal (MoM) hip replacements were used for almost a decade before adverse reactions to metal debris (ARMD) were found to be a true clinical problem. Currently, there is a paucity of evidence regarding the usefulness of systematic screening for ARMD. We implemented a systematic review ...

Sensitivity and specificity of blood cobalt and chromium metal ions for predicting failure of metal-on-metal hip replacement Blood metal ions have been widely used to investigate metal-on-metal hip replacements, but their ability to discriminate between well-functioning and faile... AJA Hart - 《...
(HealthDay) -- While thousands of Americans have benefited from hip replacements over the years, problems with metal-on-metal implants can lead to troubles requiring surgery to replace defective devices, experts say.
hip replacements per ormed worldwide each year. Wear over time o the plastic components in hip replacement has traditionally been the limitation in the durability o these implants, especially in young patients. Improved weight-bearing sur aces such as ceramic-on-ceramic and metal-on-metal were ...
