Abstract
A spinal prosthetic device ( ) which is hydraulically expanded or retracted, either pre-implantation or in-situ, thereby being adjustable for the exact intravertebral axial spacing required for the patient. Thrust bearing members ( ) are positioned between the vertebra engaging members ( ) and a pair of bellows ( ), allowing the collapsible/expandable bellows ( ) to be rotated with respect to the vertebra engaging members ( ). The device ( ) can be readjusted, on an out-patient basis, months after initial implantation. The spinal prosthetic device ( ) offers all degrees of motion afforded by the anatomical spinal disc and by virtue of incorporating no rubbing contact of any parts, exhibits and infinite working life. The spinal prosthetic device ( ) reproduces the same hydraulic load bearing capability as the nucleus pulposis and flexural freedom of movement similar to the annulus fibrosis.
