Abstract:
A polyaxial bone screw assembly includes a threaded shank body having an integral upper portion receivable in an integral receiver, the receiver having an upper channel for receiving a longitudinal connecting member and a lower cavity cooperating with a lower opening. A down-loadable compression insert has a lower friction fit collet and an outer receiver press fit surface. A down-loadable retaining ring has at least one inner edge and outer tiered surfaces. The ring cooperates with the shank to provide for pop- or snap-on assembly of the shank with the receiver either prior to or after implantation of the shank into a vertebra. The shank and receiver once assembled cannot be disassembled. A uni-planar assembly is included.

Claim (Index 12):
A uniplanar bone anchor assembly for securing an elongate rod to patient bone with a closure top, the uniplanar bone anchor assembly comprising:\n a shank having a shank head at a proximal end and a unitary anchor portion extending distally from the shank head for fixation to the bone, the shank head having a partial spherical shape with a flat planar outer surface portion on at least one side; a receiver having a top portion with upwardly extending arms defining an open channel for receiving the elongate rod, and a base defining a cavity in communication with the open channel and having a distal opening in communication with a bottom surface of the base, the upwardly extending arms including a mating structure for mating with the closure top, the cavity including an inner groove extending at least partially circumferentially around the cavity; and a bearing element having a central passage configured to receive the shank head, an outer surface sized and shaped for insertion into the inner groove of the receiver cavity, and at least one flat planar inner surface portion configured to contact the flat planar outer surface portion of the shank head so as to restrict a pivotal motion of the shank relative to the receiver to only one plane, wherein the receiver cavity inner groove and the bearing element are designed in a complementary manner such that the bearing element is positioned in the inner groove in a predetermined alignment with respect to the receiver channel.
