Abstract

An improved polyaxial mechanism is disclosed. The mechanism preferably works in conjunction with a bone plate and fixation mechanism, such as a screw, rod, or the like. The improved polyaxial mechanism increases the strength of the locking among the locking mechanism, fixation mechanism, and bone plate. In addition, the improved polyaxial mechanism allows for easy locking among the elements, as well as more difficulty in unlocking the elements. A method for utilizing the improved polyaxial mechanism is also disclosed.
