摘要： 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.

摘要： A knee cutting instrument apparatus includes an elongated alignment rod that can enable a surgeon to define alignment with a patient's long bone. An instrument block body can slide upon the alignment rod between its end portions. A locking member forms a connection with the rod at a selected position along the rod. The locking member includes a cam locking arrangement that rotates about a pivot on the instrument body. The cam has a handle portion or arm that enables a user to rotate the cam and its locking tab about its pivot. Part of the locking cam includes a locking tab having a slot that extends circumferentially about ninety degrees (90.degree.) around the pivot of the cam. The slot is positioned radially in between the pivot and the periphery of the locking member at a locking member bearing surface. The slot provides a closed end portion and an open end portion that communicates with the locking member periphery at a positioned spaced away from the bearing surface. The slot is preferably sufficient long enough that it extends circumferentially the full length of the bearing surface.

摘要： 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.
