Update from an Ohio Depuy Hip Recall Attorney
DePuy Orthopeadics, a unit of Johnson & Johnson, recently announced
that it is phasing out production of all-metal replacement hips. This
includes the recalled all-metal model known as the Articular Surface Replacement,
or A.S.R., and the all-metal Pinnacle model. The company states its decision
its decision is made due to the declining demand and in light of U.S.
regulators seeking new rules for the products.
This announcement is not surprising given the apparent design flaws and
early failure rates in these devices. Johnson & Johnson currently
faces over 10,000 lawsuits related to the A.S.R. and 3,300 cases related
to the all-metal Pinnacle, according to a company filing with the Securities
and Exchange Commission.
The Problems with Metal-on-Metal Hip Implants
In conventional hip implants, the ball and cup have a ceramic or plastic
surface. These parts of the implant wear out over time as they rub against
each other. The idea behind the ASR and Pinnacle implants was to make
the moving parts out of a more durable material-metal, a cobalt-chromium
alloy to be specific. But these "metal-on-metal" implants suffer
from an inherent design flaw: they release metal ions as the surfaces
of the ball and cup rub together. These tiny atom- sized particles of
cobalt and chromium are released into the surrounding tissues causing
inflammation and pain. They also get into the blood stream and travel
throughout the body where they can potentially damage organs such as the
heart and brain.
