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 8):
An assembly for fixing a fixation rod to a bone anchor having a head and an elongated shank with a bone engaging portion, the assembly comprising:\n a receiver including opposed upright arms defining a slot therebetween sized for receiving the rod therein, a base portion defining a bottom opening in communication with the slot sized to receive the shank of the bone anchor therethrough and an internal surface adjacent the bottom opening for supporting the head of the bone anchor, the receiver further defining an aperture passing through each of the upright arms transverse to the slot; an insert having a base configured for slidable insertion between the upright arms of the receiver, the base defining a rod support surface supporting the rod thereon when the insert is within the receiver, the base further defining an central opening for providing access to the head of the bone anchor therethrough, the insert further including a pair of opposed insert arms extending from the base to define a slot configured to receive the rod therebetween, each of the insert arms including a tab projecting therefrom and configured to be received within an aperture in a corresponding one of the receiver upright arms, each tab defining a outer tapered face configured to bear against the receiver upright arms as the insert is advanced into the slot of the receiver, the outer tapered face configured to deflect the tabs inward toward each other until the insert is advanced far enough into the receiver for the tabs to align with and snap into the apertures in the receiver upright arms; and wherein each tab is located adjacent a top surface on each insert arm.
