Dependent claims

An intervertebral prosthetic disc, comprising:

a) a superior endplate;
b) an inferior endplate;
and
c) a core including a plurality of core modules slidably disposed between the superior endplate and the inferior endplate so as to allow translation of the superior endplate and the inferior endplate with respect to one another, each of the core modules in a directly abutting relationship with one another, thereby constraining movement of the core modules relative to one another, wherein the superior endplate and the inferior endplate are each configured to receive at least a portion of the core.
