Trident Ceramic Bearing Surface
Today, hip replacements are helping to meet greater demands of younger, more active patients. To accomplish this and reduce potentially early failure, alternate bearing surfaces have been developed to help minimize the amount of wear and increase the material strength in total hip replacement bearings. Laboratory and clinical data indicate that ceramic bearings may be the most significant advancement in total hip replacement wear performance, helping to reduce wear to near undetectable levels.
Features & Benefits
Key advantages include:
-
Less Wear
The insert and head of the Trident Ceramic System are both made of alumina ceramic, which has demonstrated significantly lower wear versus conventional plastic-on-metal1,2 or metal-on-metal1,2 joint systems in the laboratory. It is anticipated that the improved wear characteristics of alumina ceramic will result in a longer lasting implant. -
Patented Titanium Sleeve
The Trident Ceramic Acetabular System is a unique design that features a patented Titanium sleeve encapsulating the ceramic that is pre-assembled at the factory. The titanium sleeve helps to increase the material strength of the ceramic insert by 50 percent versus other ceramic inserts on the market.1 -
Time-testing in U.S. Clinical Study
Stryker initiated the first U.S. Clinical Study of contemporary ceramic-on-ceramic hip replacements in 1996. The clinical study includes over 1,500 hip surgeries at 16 Centers in the United States.
