BACKGROUND AND PURPOSE: Hip prostheses that use a metal-on-metal articulation
expose the brain to elevated metal concentrations that, in acute excess due to prosthesis …

Hip resurfacing arthroplasty (HRA) has a long clinical history and has utilized a variety of
bearing material combinations with mixed clinical success. This paper reviews the local and …

There is public concern over the long term systemic health effects of metal released from hip
replacement prostheses that use large-diameter metal-on-metal bearings. However, to date …

Adverse reactions to metal particle debris have been increasingly reported as a
complication following large head metal-on-metal (MoM) hip arthroplasty. Elevated metal ion …

Background: High failure rates of metal-on-metal (MoM) hip implants prompted regulatory
authorities to issue worldwide safety alerts. Circulating cobalt from these implants causes …

Background Metal-on-metal hip resurfacing arthroplasty (MOM HR) has become an
established alternative to traditional metal-on-metal total hip arthroplasty (MOM THA) for …

Background and purpose—Muscle atrophy is seen in patients with metal-on-metal (MOM)
hip implants, probably because of inflammatory destruction of the musculo-tendon junction …
