prodisc C Goals
Maintain Spinal Balance and Motion
Degenerative disc disease can destabilize segments over time. In addition, performing the surgical discectomy is inherently destabilizing, as it involves the removal of the Anterior Longitudinal Ligament, the disc, and often, the Posterior Longitudinal Ligament. In the absence of these restricting structures, it isimportant for a disc replacement to have constraints in order to protect the facet joints.
In order to provide constraint, the prodisc mechanism of action enables movement with a fixed center of motion, enabling A/P translation only with flexion / extension.
