New York, N.Y. -- With the recent FDA approval of the Trident® Ceramic
Acetabular System, Dr. Strauss an orthopaedic surgeon at Mt. Sinai Medical
Center, NY, can now offer a better option to more active patients whose
mobility is limited by arthritis, osteoporosis or joint injury. Stryker Howmedica
Osteonics' Trident® ceramic insert is patented based on its innovative
multifunctional design.  Key features include a titanium sleeve, which
increases the ceramic insert strength by 50%, and a peripheral rim designed
to protect the ceramic insert from impingement against the neck of the stem.  

Arthritis affects an estimated 36 million Americans, or one in eight people.
About 300,000 people each year benefit from hip replacements, which
significantly decrease hip pain, restore mobility and improve their overall
quality of life. After six years of clinical trials, the widespread availability of a
new ceramic-on-ceramic bearing surface for hip reconstruction is a
breakthrough for patients who are looking forward to a more active lifestyle.

The recently approved Trident® Ceramic Acetabular System, developed by
Howmedica Osteonics, the orthopaedic implant division of Stryker
Corporation, features alumina ceramic bearing surfaces, which demonstrate
significantly less wear than traditional systems in hip simulation testing
because of an extremely low degree of friction. The components of traditional
artificial hip replacements, which feature metal on plastic surfaces, can wear
over time, releasing debris into the joint and surrounding tissues. This wear
debris, which may be more common in younger, more active patients, can
cause a loss of bone called osteolysis, a leading cause of implant failure.

“People can now benefit from hip replacement while they are young enough
to enjoy their favorite activities, like golfing, biking or tennis,” says Dr. Strauss.
“In the past, hip systems traditionally performed well for approximately 10-15
years. Many eligible patients put off the procedure to avoid the prospect of
returning for a revision.”

implants, call Dr. Strauss, at 1-212-241-1648.  For more information about the
