Abstract
A prosthetic spinal disc may include a nucleus and an annulus that together may be optionally shaped, using a computed tomography (CT) scan, ultrasound imaging and/or magnetic resonance imaging (MRI). The nucleus includes a central area having a material density that is different than the material density of the annulus. The nucleus may alternately include an area for the introduction of a central supporting fluid or gel. An optional fiberoptic carriage may be used to provide tissue ingrowth from the supported vertebrae and optional internal baffling provides additional stabilization.
