Claim 18:
19. A method comprising:
fastening two or more spinal rod anchoring devices into two or more vertebrae, wherein each spinal rod anchoring device comprises:
a body comprising a distal end and a proximal end, wherein a threaded bone anchor extends along a longitudinal axis and is positioned toward the distal end, and a U-shaped head portion is positioned toward the proximal end, wherein the head portion and the threaded bone anchor are fixedly attached;
a saddle comprising a convex curvature at its lower surface and a concave interior region, wherein the interior region has an open channel therewithin, wherein the convex curvature of the saddle is slidably seated within a concave base of the head portion for arcuate sliding movement of the saddle relative to the head portion, wherein the open channel is sized to allow at least a portion of the saddle to extend beyond the head portion during the arcuate sliding movement and wherein a spinal connection element is configured to be disposed on the saddle;
a retaining pin configured to be inserted along the longitudinal axis through the channel in the saddle and secured in a groove, wherein the groove is centrally positioned within the base of the head portion, wherein the retaining pin slidably secures the saddle to the head portion;
a closure mechanism configured to be positioned within the head portion;

positioning the spinal connection element about a single axis relative to the body of a first spinal rod anchoring device, wherein the positioning comprises translating and angulating the saddle within the head portion;
positioning the spinal connection element attached to the first spinal rod anchoring device and;
interconnecting at least a second rod anchoring device with the spinal connection element;
wherein the U-shaped head portion includes channels disposed about side surfaces of the extensions.
