A vertebral implant for interposition between two vertebral endplates comprises a first endplate assembly for engaging a first vertebral endplate, a second endplate assembly for engaging a second vertebral endplate, and a first flexible core component interposed between the first and second endplate assemblies. The first flexible core component comprises first and second end portions. The first end portion is coupled to the first endplate assembly to prevent translation of the first end portion with respect to the first endplate assembly, and the second end portion is pivotable with respect to the second endplate assembly.
