Abstract

An artificial disc having a pair of opposing plates (100, 200) for seating against opposing vertebral bone surfaces, separated by at least one spring mechanism. The preferred spring mechanism is at least one belleville washer (130) having radially extending grooves,although belleville washers having radially spaced concentric grooves, and belleville washers having a radially varying thickness are also disclosed for use herein. Preferably, the belleville washer utilized has a narrow end that is modified to mount onto a semispherical protuberance (201) on a plate, and a wide end that seats for expansion against an opposing plate. The narrow end of the belleville washer is modified by having a curvate socket that can be rotatably and angulatably mounted to the semispherical protuberance.
