摘要： A dynamic spine prosthesis (such as a facet joint prosthesis having an articulation surface configured to articulate with a corresponding facet joint element) that has a fixation element with an elongated bone entry portion defining a longitudinal axis and a dynamic spine prosthesis component connected to the fixation element at a connection location by an adjustable connection. The adjustable connection has first and second washers each rotatably supported by the fixation element and each having an angled contact surface in a plane not perpendicular to the longitudinal axis of the fixation element, with the connection location being between the bone entry portion and the first and second washers.

摘要： The invention discloses methods, devices, systems and kits for repairing, replacing and/or augmenting natural facet joint surfaces and/or facet capsules. An implantable facet joint device of one embodiment comprises a cephalad facet joint element and a caudal facet joint element. The cephalad facet joint element includes a member adapted to engage a first vertebra, and an artificial cephalad bearing member. The caudal facet joint element includes a connector adapted for fixation to a second vertebra at a fixation point and an artificial caudal bearing member adapted to engage the cephalad bearing member. The artificial caudal bearing member is adapted for a location lateral to the fixation point. In another embodiment, an implantable facet joint device comprises a cephalad crossbar adapted to extend mediolaterally relative to a spine of a patient, the crossbar having opposite first and second ends, a connector element adapted to connect the crossbar to a first vertebra, a first artificial cephalad bearing member adapted for connection to the first end of the crossbar and adapted to engage a first caudal facet joint element connected to a second vertebra, and a second artificial cephalad bearing member adapted for connection to the second end of the crossbar and adapted to engage a second caudal facet joint element connected to the second vertebra. In yet another embodiment, an implantable facet joint device comprises a caudal cross-member adapted to extend mediolaterally relative to a spine of a patient and adapted to connect to a first vertebra, a first artificial caudal bearing member adapted for connection to the caudal cross-member, and adapted to engage a first cephalad facet joint element connected to a second vertebra, and a second artificial caudal bearing member adapted for connection to the caudal cross-member at a predetermined spacing from the first bearing member, the second bearing member being adapted to engage a second caudal facet joint element connected to the second vertebra.
