An intervertebral implantation system for restoring disc height and vertebral alignment, while allowing dynamic mobility and stabilization of the vertebral segment, and minimally invasive methods of implanting the same. The implantation system includes an annular reinforcement implant, including an elastomeric balloon inserted into the hollow or interior of a tubular sleeve, and secured only at a first and second neck portions to a securement element coupled to an attachment fixture, forming an annular structure attached to the outer margin of the annulus fibrosus. When the prosthetic implant is in a contracted state the tubular sleeve is redundant and undulated, forming folds, gathered loosely around the circumference of the inner balloon. Upon pressurized inflation with in-situ curable polymer, the elastomeric balloon elongates and expands circumferentially, and the tubular sleeve stretches and unfolds, constraining further expansion and elongation of the elastomeric balloon. The attachment fixture is configured to provide secure attachment to the outer margin of the annulus fibrosus. A temporary, high pressure vertebral distraction balloon is utilized to aid in vertebral distraction during a surgical procedure to implant the annular reinforcement implant.
An inflatable prosthetic device for placement within at least a portion of an annulus fibrosus of a patient, said prosthetic device comprising:
