Apparatus and method for sculpting the surface of a joint

An apparatus for replacing the surfaces of a joint between a first bone and a second bone, the first bone moving in a predetermined manner with a second bone, the apparatus comprising:

• a first bone arthroplasty including a plurality of first bone sub-components structured for mimicking and replacing a bearing surface of the first bone, wherein each of said plurality of first bone sub-components has an inner surface structured to be secured to the first bone and an outer surface;
• and
• a second bone arthroplasty including a unitary baseplate or a plurality of baseplate sub-components structured for mimicking and replacing a bearing surface of the second bone;
• and
• at least one flexible interconnect mechanism structured to slidably interconnectedly receive two adjacent first bone sub-components or two adjacent second bone baseplate sub-components,
• wherein the outer surface of said plurality of first bone sub-components contact said second bone arthroplasty and further wherein each of said adjacent interconnected first bone sub-components or said adjacent interconnected second bone baseplate sub-components have relative angular motion one to the other and are structured to be partially constrained upon assembly and partially constrained when fully assembled, the resulting configuration of the first bone arthroplasty and second bone arthroplasty articulating in a predetermined manner to restore proper kinematics.
