Abstract:
A spinal screw assembly providing an adjustable securement of a fixation rod across at least two vertebrae. The assembly includes a pedicle screw having a spherical head portion, a threaded shaft portion and a tool engagement surface in the head portion for use in driving the screw into a vertebrae. The head portion of the screw is positioned in a body member adjacent a curvilinear surface disposed about an aperture in the end of the body member such that the shaft portion of the screw extends therethrough and the curvilinear inner surface abuts and mates with the head portion of the screw so as to define a ball joint therewith. The body member additionally defines a pair of opposed parallel slots therein adapted to receive a portion of the fixation rod and a locking cap bears against the fixation rod to releasably secure the rod within the assembly.

Claim (Index 17):
A bone screw assembly for securing a fixation rod to a bone via a closure, the bone screw assembly comprising:\n a bone screw having a distal threaded shank and a proximal head; a body member having an axial bore extending between a proximal end and a distal end of the body member and an open channel at the proximal end adapted to receive the fixation rod, the axial bore including a distal seating surface in which the bone screw proximal head is adapted to be pivotally seated, a distal opening through which the bone screw extends, opposed non-threaded downward facing surfaces formed into the axial bore above the distal seating surface, and a proximal closure mating structure; and a compression bushing disposed in the body member axial bore in an at least partially overlapping position under the opposed non-threaded downward facing surfaces, the compression bushing being directly biased against the body member so as to cooperate in exerting a distally-directed force toward the bone screw proximal head and establish a frictional articulatable arrangement between the bone screw proximal head and the body member seating surface, so as to maintain the body member in a desired angular orientation relative to the bone screw before locking the fixation rod within the body member channel via the closure.
