摘要:
A dynamic spine prosthesis (such as a facet joint prosthesis having an articulation surface configured to articulate with a corresponding facet joint element) that has a fixation element with an elongated bone entry portion defining a longitudinal axis and a dynamic spine prosthesis component connected to the fixation element at a connection location by an adjustable connection. The adjustable connection has first and second washers each rotatably supported by the fixation element and each having an angled contact surface in a plane not perpendicular to the longitudinal axis of the fixation element, with the connection location being between the bone entry portion and the first and second washers.
