Additional complications from the hip replacement system may include increased metal ion levels in the blood, bone staining, necrosis, swelling, nerve ...
Metallosis. Metallosis is the medical condition involving deposition and build-up of metal debris in the soft tissues of the body. [1] Metallosis has been known to occur when metallic components in medical implants, specifically joint replacements, abrade against one another.

Over time, healing occurs by new blood vessels infiltrating the dead bone and removing the necrotic bone which ...

Hip resurfacing is generally more suitable for younger people who are not morbidly obese, are clinically qualified for a hip replacement (determined by the doctor), have been diagnosed with noninflammatory degenerative joint disease, do not have an infection, and are not allergic to the metals used ...
DePuy said the recall was due to unpublished National Joint Registry data showing a 12% revision rate for resurfacing at five years and an ASR XL revision rate of 13%. All hip prostheses fail in some patients, but it is expected that the rate will be about 1% a year. [144] Pathologically, the failing prosthesis had several effects.
