The Food and Drug Administration (FDA), pursuant to Section 522 of the Food, Drug and Cosmetic Act, 21 USC § 3601, has ordered medical device manufacturers, including Zimmer, Inc. (“Zimmer”), to conduct post market surveillance studies of their metal-on-metal hip implants. ...
tracking the safety of metal-on-metal hip implants in recipients. But in theNEJMarticle, Rising and colleagues noted that most of these studies have yet to begin and their first results will take years to arrive.
In this article, a concise review of the current literature on metal-on-metal hip resurfacing (MoMHR) is given. In contrast to conventional total hip arthroplasty, older age, female sex and small femoral head sizes predispose to failure. Neck fracture and metal wear-related complications account...
Bioengineering reasons for increased wear and failure of metal-on-metal (MoM) bearings in hip prostheses have been described. Low wear occurs in MoM hips when the centre of the femoral head is concentric with the centre of the acetabular component and the implants are correctly positioned. Transl...
The Immunology Devices Panel of the Medical Devices Advisory Committee recently met to provide advice and recommendations to the FDA about immunological responses to metal-containing products regulated as medical devices, including metal-...

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 ...
Background: Modern hip implants typically feature modular heads, which allow for easy exchange and removal from the femoral stem at the time of revision. However, owing to fretting, corrosion, or cold welding, the modular head may be difficult or impossible to separate from the underlying trunnio...
