A spinal implant includes a first leg configured to abut a surface of an inferior articular process of a first vertebra that forms one portion of a spinal facet joint between the first vertebra and an adjacent second vertebra, a second leg configured to abut a surface of a superior articular process of the adjacent second vertebrae that forms another portion of the spinal facet joint between the first vertebra and the adjacent second vertebra, and a cross-member connected between the first and second legs and maintaining the first and second legs in a spaced-apart relationship. The spinal implant may restrict flexion and/or extension of the spinal facet joint when received about the spinal facet joint.
