Abstract
A spring member for an artificial intervertebral disc includes a substantially annular body including an axially extended bore therethrough defining a passageway. A seat extends radially inward towards the bore for seating therein a bearing member for adjusting and compensating vertebral disc motion. An engagement member extends radially outwardly from the bore for engaging a housing member and securing the spring member within the housing member. The spring member absorbs compressive loads between the bearing member and the housing member while controlling motion and position of the bearing member.
