Title: Artificial intervertebral disc having a captured ball and socket joint with a solid ball and compression locking post

Abstract: An artificial disc having a pair of opposing baseplates, for seating against opposing vertebral bone surfaces, separated by a ball and socket joint that includes a ball compression locked to a post extending from one of the baseplates. The ball is captured within a curvate socket formed in a peak of a convex structure attached to the other of the baseplates. The socket is formed by opposing curvate surfaces, one on the convex structure and one on the other of the baseplates. The ball rotates and angulates in the socket. The ball and socket joint therefore permits the baseplates to rotate and angulate relative to one another.
