Disc prosthesis having remote flexion/extension center of rotation

摘要: An intervertebral disc prosthesis comprises a first endplate, second and bearing surface positioned between the endplate endplate. The may be provided by mobile including convex configured to engage concave multiple surfaces of articulating on endplates form plurality joints. Each joint is facilitate particular type movement for segmental unit. Furthermore, each defined distinct center rotation. contact pair formed component provide flexion/extension rotation prosthesis. lateral bending/torsional
