    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.
