    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.

    摘要： The present invention relates to a locking mechanism and method of locking the relative positions of a fixation device like a bone screw and of a stabilization device like a rod. The locking mechanism includes a seat, a washer and a cap. The seat includes a bottom portion configured to receive the fixation device such that a socket of the bottom portion engages part of the fixation device and prevents the fixation device from passing entirely therethrough. The seat further includes a side portion configured to receive the stabilization device, a washer and a cap. When the washer and cap are fully engaged with the seat, the fixation device may be locked independent of the stabilization device. The locking mechanism may also include a locking element for locking the stabilization device.
