1. A robotic system for distraction of a disc space for implantation of an intervertebral disc prosthesis, the system comprising:
a 3D modeling system for creating a 3D model of first and second vertebra adjacent the disc space and identifying positions of the first and second vertebrae and generating and storing position data for the positions of the first and second vertebrae;
a robotic distractor configured to precisely open the disc space just large enough to receive a selected intervertebral disc;
a computing system for storing and processing the 3D model and the positions of the first and second vertebrae before and after distraction; and
a surgeon interface on the computing system configured to allow the surgeon to select an intervertebral disc prosthesis to be implanted and a desired distraction distance to be achieved or a desired distraction force to be applied by the robotic distractor.
