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 21):
A spinal screw assembly for securing a fixation rod to patient bone via a closure, the spinal screw assembly comprising:\n a screw having a longitudinal axis, a head portion including a first thread form on an outer surface thereof, and a threaded shaft portion extending distally from the head portion for attachment to the bone; a body member having a lower portion defining a bottom opening, an upper portion defining an open first channel for receiving the fixation rod, and an axial bore having a width centered around a longitudinal axis, the axial bore communicating with a bottom of the body member through the bottom opening and extending upwardly through the open first channel to a top of the body member, the axial bore including a narrowed width adjacent the bottom opening defining an interior seating surface, the bottom opening having a second thread form threadably mateable with the first thread form, the axial bore being sized to permit downward passage of the screw threaded shaft portion therethrough while preventing the screw head portion from exiting the body member through the bottom opening by engagement with the interior seating surface; and a bushing member disposed within the axial bore and engageable with the screw head portion so as to at least partially inhibit the screw head portion from moving upward within the axial bore prior to the insertion and securement of the fixation rod via the closure.
