Artificial spinal disk

A surgical kit for spinal surgery comprising:

• a first bone plate, wherein the first bone plate is configured for attachment to a first vertebral body;
• a second bone plate, wherein the second bone plate is configured for attachment to a second vertebral body;
• a central capsule, wherein the central capsule is configured to couple to said first bone plate and said second bone plate, wherein said central capsule comprises:
• a first and second endplate each having a concave surface;
• a first sliding disk and a second sliding disk configured to fit with the concave surfaces of said first endplate and said second endplate respectively, and wherein each of said sliding disks has an opening therethrough and is attached to a respective one of said endplates with a retainer disk attached to a post coupled to said respective endplate, said post extending through said opening, and wherein said retainer disk has a surface larger than said opening in the sliding disk to slidably capture said sliding disk between said retainer disk and said concave surface of said endplate such that said sliding disk slides along and between spaced apart surfaces of said retainer disk and said endplate;
• wherein the first bone plate and the second bone plate attach to said central capsule via grooves on each of said first and second bone plates which slidably attach to tongues on each of said first and second endplates;
• and
• wherein said first bone plate, said second bone plate, and said central capsule are uncoupled from one another to allow for separate placement into the disk space during spine surgery.
