FDA OKs Hip Resurfacing System
Metal Devices Used to Replace Parts of Damaged Hip Joint
The Birmingham Hip Resurfacing System web site states that the resurfacing
system "has been in clinical usage for 8.5 years in its current form,
during which time patient results have been at least as good as conventional
replacement in the indicated age group.
"But long-term results of this procedure are not yet known, and the
usual risks associated with any hip replacement apply, including infections,
damage to blood vessels, dislocation of the hip, thrombosis, anesthetic risk,
and your doctor may inform you of other potential risks," states the
product's web site.
"Metal on metal hip resurfacing is also associated with an increase of
metal ions in the blood and urine," the web site notes. "All evidence
to date has shown no correlation with metal ions with the Birmingham Hip
Resurfacing System and any health problems. More studies are being done on the
effect of metal ions in pregnancy and in patients
"Most doctors would suggest that metal on metal devices should not be
used in these two groups," states the web site.
