A modular implant that is effective to replace a damaged or degenerated spinal disc is provided. The implant includes a central core member having superior and inferior surfaces, a superior endplate member having a bone-contacting surface and a mating surface effective to mate with the superior surface of the central core member, and an inferior endplate member having a bone-contacting surface and a mating surface effective to mate with the inferior surface of the central core member. The modularity of the implant allows the surgeon to select and properly fit each modular endplate member separately during the surgical procedure, thereby eliminating the need to prepare the endplates of each adjacent vertebrae, and/or the bone-contacting surfaces of the implant.
