Abstract
An implantable vertebrae prosthesis for use in aligning and strengthening the adjacent vertebrae in the lumbar region of the spinal column is disclosed. After implantation, the prosthesis maintains a low profile and is usually not felt by the patient after healing. The prosthesis is designed to provide support to the degenerative lumbar region of the spine. The spinal fixation apparatus includes a cortical screw, a connecting rod, a cylindrical plug, an adjustable cap, a block, and a retaining nut which will lock together when the retaining nut is tightened to lock all of the components together as a unit after implantation. The prosthesis is self-locking.
