Abstract:
A polyaxial bone screw assembly includes a threaded shank body having an upper portion, a receiver member or head, a retaining and articulating structure, and a pressure insert disposed between the shank upper portion and a rod. The receiver has a U-shaped cradle defining a channel for receiving a spinal fixation rod and a receiver cavity. The retaining and articulating structure attaches to the shank and rotates with the shank in the cavity during positioning. The pressure insert presses upon the shank upper portion and not the retaining and articulating structure.

Claim (Index 1):
A receiver of a bone anchor, the receiver being configured to accept a rod that is locked in the receiver via a closure top, the receiver comprising:\n a receiver body having a longitudinal axis, a base, and a pair of upright arms extending upwardly from the base to define an open channel for receiving the rod, the open channel having a transverse axis perpendicular to the longitudinal axis and opening through front and back outer faces of the receiver body, the upright arms having opposed interior surfaces mateable with the closure top to securely lock the rod within the open channel, the receiver body having side outer faces opposite the interior surfaces of each upright arm and extending along the base, and top side surfaces defining a top of the receiver body; and at least one horizontally-elongated upper tool engaging groove formed into the side outer face of each upright arm, each upper tool engaging groove being spaced an equal distance below the top side surfaces and extending to at least one of the front outer face and the back outer face, wherein the front and back outer faces of the receiver body include first substantially planar outwardly-facing surfaces adjacent and extending below the open channel, the first substantially planar outwardly-facing surfaces being perpendicular to the open channel transverse axis and parallel to the receiver longitudinal axis, and wherein the side outer faces of the receiver body each include a second substantially planar outwardly-facing surface below the upper tool engaging groove, the second substantially planar outwardly-facing surfaces being parallel to both the open channel transverse axis and the receiver longitudinal axis.
