Abstract
Abstract The Moskovich facilitator facilitates the insertion of bone grafts between two vertebrae. The invention has two flat tong-like guides that distract the vertebrae as the graft slides between the two guides towards the vertebrae. The two guides have grooved surfaces to keep the graft from rotating or from slipping laterally. The two guides each have a lip to keep them from slipping too far in between the vertebrae. The two guides can be combined by an elbow piece into one part. The elbow is offset to permit impacting the graft directly on the angle of the axes of the guides. The two guides each have a notch, and the two notches hold an inserter/extractor. The screw-type inserter/extractor slowly rams the graft in between the vertebrae without impact, and slowly extracts the guides after the graft is seated.
