An artificial intervertebral disc includes housing members including
spaced inner surfaces facing each other and oppositely facing outer
surfaces for engaging spaced apart vertebral surfaces. Bearing surfaces
extend from each of the inner surfaces for engaging each other while
allowing for low friction and compression resistant movement of the
housing members relative to each other while under compression. Load
sharing pads are disposed between the inner surfaces and about at least a
portion of the bearing surfaces for sharing absorption compressive loads
with the bearing surfaces while limiting the relative movement of the
housing members.
