A cervical fusion screw guide includes a tube through which a drill or a bone screw can be passed, and a needle-like probe which is offset from the axis of the tube. The probe may extend parallel to or at an angle oblique to the tube axis. An assortment of the guides, having different offset distances and differing angles, are provided. Alternatively, a single adjustable probe, having a variable probe angle and/or a variable probe offset, may be used.
