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 1):
A spinal screw assembly for securing a fixation rod to a bone via a closure, the spinal screw assembly comprising:\n a pedicle screw comprising a screw head and an elongated shank extending from the head and having a threaded bone engaging portion; a body member comprising opposed upright arms defining a first slot therebetween sized for receiving the fixation rod therein, a base portion defining a bottom opening in communication with the slot and sized to receive the elongated shank therethrough, and an internal surface adjacent the bottom opening for supporting the screw head, the body member defining an aperture passing through each of the upright arms transverse to the first slot; and a bushing having a base configured for slidable insertion between the upright arms of the body member, the base defining a rod support surface for supporting the fixation rod thereon when the bushing is received within the body member and a central opening for providing access to the screw head therethrough, the bushing further including a pair of bushing arms extending upward from the base to define a second slot configured to receive the fixation rod therebetween, each of the bushing arms including a tab projecting outwardly toward the apertures and configured to be received within one of the apertures in a corresponding one of the body member upright arms when the bushing is disposed within the body member, each tab defining a beveled face with respect to a longitudinal axis extending through the bushing and configured to bear against interior surfaces on the body member upright arms as the bushing is advanced into the first slot of the body member, wherein the beveled faces of the bushing tabs are configured to deflect the bushing arms inward toward each other until the bushing is advanced far enough into the body member for the bushing tabs to align with and snap into the apertures in the body member upright arms.
