The disclosure 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.
