1. A spinal implant system, comprising:
a facet implant member for positioning in a facet joint, the implant having a proximal end
and distal end; and
a lateral mass fixation member attached to or attachable to the facet implant member at
the proximal end, wherein the lateral mass fixation member comprises:
an anchor comprising:
a rod receiving member, and
at least one attachment device for attaching the rod receiving member to
the facet implant member; and
a rod received in the anchor to bridge a lateral mass of adjacent vertebrae,
wherein the facet implant member has a longitudinal axis, the facet joint has a longitudinal axis, and, in use, the longitudinal axis of the implant and the longitudinal axis of the facet joint are generally parallel or coaxial,
wherein the at least one attachment device is received by the facet implant member along the longitudinal axis of the implant, and at least a portion of both the rod receiving member and the attachment device extend from the proximal end of the implant and are configured to extend outside of the facet joint.
