Prosthetic Spinal Disc Nucleus Having Selectively Coupled Bodies

The present invention relates to the first prosthetic body 22 and the second prosthetic spinal disc nucleus comprising a prosthetic body 24 and coupling means 26. The first and second prosthetic bodies 22, 24 each have a volume less than a volume of sufficient structural integrity and haekgang 96 to maintain a desired separation between the vertebrae of the opposed pair. Coupling means (26) combines the first prosthetic body 22 is selectively and the second prosthetic body 24. During use, the first prosthetic body 22 is inserted into the haekgang 96 through the opening 100 in the Yun 94. The coupling means 26 is composed so as not to hinder the insertion of the second prosthetic body 24, the first prosthetic body 22. The second prosthetic body 24 are inserted similarly. After implantation, the coupling means 26 is re-Yun 94, the prosthetic spinal disc nucleus (20) or a any claim to prevent subsequent movement being a part of the first and second prosthetic through the opening 100 in the body ( the 22, 24) causes a relatively fixed. Prosthetic body, the coupling means, the prosthetic spinal disc nucleus, haekgang, flexible
