Abstract
A cannulated screw having a resilient balloon structure capable of supporting compressive and cyclic loads. The balloon provides an artificial disc prosthesis by use of the balloon that mimics the properties of the natural disc by maintaining the intervertebral disc space through a full range of natural motion, absorbing shocks and permitting a natural range of motion.

A cannulated screw comprising:
- a hollow body with an open first end and an open second end, a balloon body secured to said open first end with a ferrule element, said balloon body extending entirely into said hollow body when in a non-deployed position and extending out of said hollow body when volumetric material is directed through said open second end causing expansion of said balloon body in a deployed position, a threaded cap attached to said open second end, said threaded cap having threads positioned along an inner surface, and a locking plug securable to said threaded cap, said locking plug maintaining volumetric material in said balloon body to maintain said balloon body in the deployed position.
