Five stories to read for the latest in metal-on-metal hip research (Healio)
The use of metal-on-metal hip bearings in total hip arthroplasty is a controversial topic in orthopedic surgery. Here, Orthopedics Today spotlights five articles that focus on recently published research in metal-on-metal total hip arthroplasty.
Metal-on-metal implants long-lasting, potentially dangerous
The European Commission recently released a fact sheet detailing the advantages, disadvantages and potential health risks for patients who opt for metal-on-metal hip implants. Read more.
Noted surgeon: Also follow patients with small diameter MoM heads for ARMD
DALLAS — Although some surgeons have looked to the use of smaller heads to circumvent the potential for adverse reactions to metal debris in metal-on-metal total hip arthroplasties, a minimum 2-year follow-up on the use of 28- and 32-mm titanium modular acetabular components with chromium-cobalt tapered inserts cautions surgeons to closely follow metal-on-metal patients with small diameter heads as well.

High metal-ion levels, persistent pain cited as indications for revision of MoM hips
ORLANDO, Fla. — Elevated metal-ion levels, loose cups either radiographically or clinically and psychological changes are among the indications orthopedic surgeons need to consider for the revision of metal-on-metal hip articulations, according to a presenter at a recent meeting.

MoM total hip arthroplasty implants did not increase overall cancer risk
The use of MoM implants in THA was not linked to a higher risk of cancer in patients compared to the use of non-MoM devices. Read more.
Study: Smaller MoM bearings performed better for patients with degenerative joint disease
With respect to metal ion levels, the 28-mm metal-on-metal bearing performed better than the 36-mm metal-on-metal bearing among patients with unilateral noninflammatory degenerative joint disease, according to results of a recently published study. Read more.
