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 16):
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 longitudinal axis, an elongated shank centered about the longitudinal axis and having a threaded bone engaging portion, and a shank head having a spherical enlargement with a hemisphere plane perpendicular to the longitudinal axis; a body member comprising a longitudinal axis, 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, a surface adjacent the bottom opening for supporting the shank head, and an aperture passing through each of the upright arms perpendicular to the body member longitudinal axis; 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 configured to bear against interior surfaces the body member upright arms as the bushing is advanced into the first slot of the body member, wherein the bushing tabs are configured to deflect 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, and wherein the bushing base engages the shank head spherical enlargement so as to not extend below the hemisphere plane when the pedicle screw longitudinal axis and the body member longitudinal axis are co-aligned with each other.
