Abstract:

A method of implanting a spinal prosthesis comprises inserting a first member between superior and inferior spinous processes associated with respective superior and inferior vertebrae. The superior and inferior vertebrae are separated by an intermediate vertebra. The method further includes inserting a second member through a channel in the first member. After the second member is inserted, the method requires removing the second member from the channel and inserting a third member through the channel. The third member has a different stiffness than the second member. Finally, the method requires anchoring the third member to the intermediate vertebra, while the third member is inserted through the channel. The third member is anchored at first and second locations disposed on respective first and second lateral sides of the intermediate vertebra.

Abstract:

A prosthetic device for insertion in a spinal column includes a first, second, and third members. The first member includes an inferiorly extending tab and is of a relatively flexible material. The second member includes a superiorly extending tab and is of a relatively flexible material. The third member defines a superior opening for receiving the inferiorly extending tab and an inferior opening for receiving the superiorly extending tab and is of a relatively stiff material. The device also includes a means for providing a rigid connection of the third member to a vertebra.
