A spinal implant extendable across a facet joint to aid in fixation of the facet joint includes an elongate connecting member, a bone allograft, and a locking member. The elongate connecting member is sized to extend across a facet joint and includes a distal bone anchor. The bone allograft is sized for placement in a bore formed through the facet joint and configured to be placed about the elongate connecting member. The locking member includes a longitudinal bore sized to receive the elongate connecting member, and the locking member has an unlocked condition permitting movement relative the elongate connecting member and a locked condition rigidly fixing the locking member in place on the elongate connecting member. The locking member is configured to cooperate with the distal bone anchor to compress the facet joint, and the locking member is configured to lock the spinal implant across the facet joint. |
