Trident® Ceramic Hip Information

Stryker’s Trident® Ceramic Hip Replacement System

In 1999, Stryker advanced the design of hip implants with the ceramic-on-ceramic and titanium hip, representing the latest innovations in this technology with the Trident® hip replacement system. Unlike conventional hip replacement systems, the Trident® System utilizes alumina ceramic-on-ceramic surfaces rather than metal-on-plastic or metal-on-metal. Ceramic-on-ceramic components have demonstrated significantly lower wear versus the conventional systems in the laboratory. Therefore, it is anticipated that these improved wear characteristics will potentially extend the life of the implant.

The Trident® Ceramic System is a cementless system, which means that the materials are fixed to the bone through implant design and technique, rather than using bone cement. Additional technology such as arc deposition and hydroxyapatite (HA) coating are an essential part of the shell design.

Range of motion for the Trident® Ceramic System

Many people are concerned that they’ll experience a more limited range of motion following total hip replacement. Most want to regain sufficient motion so that they can return to everyday activities, such as climbing stairs and sitting or bending to tie their shoelaces, without concern for dislocation. Although there are many factors that will influence your range of motion, the Trident® Ceramic System is designed to accommodate the range of motion of a normal, healthy hip joint. An increased range of motion may minimize the risk of hip dislocation.
