Claim 7:
8. A method of securing a rod to a receiver via a closure top, the receiver configured to be used with a bone anchor, the method comprising:
providing the receiver comprising a receiver body having a pair of upright arms extending upwardly to define an open channel for receiving the rod, the open channel opening through a front outer face and a back outer face of the receiver body, the pair of upright arms comprising opposed interior surfaces mateable with the closure top to securely lock the rod within the open channel, side outer faces opposite the interior surfaces, and top side surfaces defining a top of the receiver body, a first of the pair of upright arms comprises a first horizontally-elongated upper tool engaging groove (HEUTEG) formed on a first of the side outer faces and a first planar outwardly-facing surface formed on the first of the side outer faces below the first HEUTEG, a second of the pair of upright arms comprises a second (HEUTEG) formed on a second of the side outer faces and a second planar outwardly-facing surface formed on the second of the side outer faces below the second HEUTEG, the first HEUTEG comprising a first downwardly-facing surface and a first upwardly-facing surface opposing the first downwardly-facing surface, the second HEUTEG comprising a second downwardly-facing surface and a second upwardly-facing surface opposing the second downwardly-facing surface, the first downwardly-facing surface of the first HEUTEG being spaced a first distance below the top side surface of the first of the pair of upright arms, the second downwardly-facing surface of the second HEUTEG being spaced a second distance below the top side surface of the second of the pair of upright arms, the first distance being different than the second distance, wherein the first planar outwardly-facing surface and the second planar outwardly-facing surface are parallel to each other;
providing the closure top;
positioning the rod within the open channel of the receiver body of the receiver; and
securing the rod to the receiver by threadably advancing the closure top against the rod and within the receiver body of the receiver.
