  • Publication number: 20080177332
    Abstract: Prostheses, systems, and methods are provided for replacement of natural facet joints between adjacent vertebrae using polyaxial attachment mechanisms for securing the prostheses to the vertebrae. A cephalad prosthesis attached to a superior adjacent vertebra replaces the inferior half of a natural facet joint. A caudal prosthesis attached to an inferior adjacent vertebra replaces the superior half of a natural facet joint. Both the cephalad and caudal prostheses are configured with artificial facet joint structures that include articulating surfaces that cooperate and form an artificial articular configuration. The polyaxial attachment mechanism permits adjustment of the position of the artificial facet joint structure along more than one axis at or after the time the cephalad or caudal prosthesis is attached to a vertebra.

  • Publication number: 20080177310
    Abstract: A method of treating spine disease including the steps of removing at least a portion of a natural facet joint from a vertebral body; implanting an intervertebral disc prosthesis and replacing the portion of the natural facet joint with a facet joint prosthesis. The removed facet portion may be a cephalad or a caudal facet or both. The replacing step may include the step of attaching the facet joint prosthesis to the vertebral body, such as at or near a pedicle and/or spinous process. The invention also provides spinal prostheses to treat spine disease. The spinal prostheses include an intervertebral disc prosthesis and a facet joint prosthesis having artificial facet joint structure adapted and configured to replace a removed portion of the natural facet joint (cephalad, caudal or both).

  • Publication number: 20080119845
    Abstract: A method and system for removing a portion of an artificial facet from a vertebra, and an adapter within the system that allows ultrasonic energy and extraction forces to be transmitted therethrough are provided. The method includes attaching an adapter to an ultrasonic waveguide and to a stem cemented into a vertebra, and applying ultrasonic energy and extraction force from the waveguide through the adapter to the stem. The system includes a handset that delivers ultrasonic energy, a waveguide attached to the handset to receive the energy therefrom, and an adapter attached to the waveguide to receive the energy therefrom. The adapter includes a first section attaching the adapter to the ultrasonic waveguide, and a second section attaching the adapter to a portion of the artificial facet joint having a stem embedded in a vertebra, the sections of the adapter transmitting energy and forces from the waveguide through the adapter to the attached stem.
