System and Method for Multiple Level Facet joint Arthroplasty and Fusion

A system comprising:

• a second prosthesis attachable to a first vertebra and a second vertebra of a spine to substantially prevent relative motion between the first and second vertebrae;
• and
• a first prosthesis attachable to the first vertebra independently of prevention of relative motion between the first and second vertebrae via the second prosthesis, the first prosthesis comprising a first articular surface shaped to articulate with a second articular surface on a third vertebra of the spine.
