摘要： An artificial intervertebral disc (10) comprising at least two individual disc units (24, 26) that create a single center of rotation within an intervertebral space. An artificial intervertebral disc including housing members (12, 14) including spaced inner surfaces (16, 18) facing each other and oppositely facing outer surfaces (20, 22) for engaging spaced apart intervertebral surfaces; self-adjusting bearing mechanisms operatively disposed between the inner surfaces for moving relative to the housing members to adjust and compensate for vertebral disc motion; and a flange formed on an outer surface of said housing members for aligning the disc in an intervertebral space. A method for posteriorly inserting an artificial disc assembly by inserting at least two artificial disc assemblies around a spine and into an intervertebral space.
