Abstract:
A prosthetic disc for insertion between adjacent vertebrae includes a core having upper and lower curved surfaces, upper and lower plates, and peripheral restraining structure on at least one of the upper plate, the lower plate and the core. Each plate has an outer surface which engages a vertebra and an inner curved surface which slides over the curved surface of the core. The peripheral restraining structure serves to hold the core against a curved surface of at least one of the plates during sliding movement of the plates over the core.

Claim (Index 1):
A method of making a prosthetic disc with a mobile core, the method comprising:\n providing a first plate having a first surface configured to engage a vertebra and an opposite bearing surface; providing a second plate having a first surface configured to engage a vertebra and an opposite bearing surface; providing a rigid mobile core, the core having first and second bearing surfaces configured to cooperate with the bearing surfaces of the first and second plates to allow the first and second plates to slide and translate over the core when implanted between adjacent spinal vertebrae and a lateral edge between the first and second bearing surfaces; further providing on said rigid mobile core, two or more recesses circumferentially spaced apart about the periphery of the core; and further providing on said first plate two or more pegs on the first plate, each peg opposing one of the two or more circumferentially spaced recesses, wherein the two or more circumferentially spaced recesses extend in a direction radially inward from the lateral edge of the core toward a center portion of the core; and assembling the mobile core between the first and second plates and the mobile core to form an assembled configuration for implantation between adjacent spinal vertebrae in which the core is retained between the first and second plates with the two or more pegs received in the spaced apart recesses.
