Abstract:
A receiver subassembly adapted to couple with a universal shank to form a bone anchor assembly. The universal shank having an integral upper capture structure with opposed spaced apart flat side surfaces. The receiver subassembly including a receiver including a distal opening for bottom loading of the capture structure of the universal shank there-through. The receiver supporting a retainer and a positioner within the receiver. The positioner supporting a position of the retainer within the receiver. The retainer configured to couple with the capture structure when the capture structure extends at least partially through the distal opening.

Claim (Index 15):
A pivotal bone anchor assembly for securing an elongate rod to a bone, the bone anchor assembly comprising:\n a bone anchor having a capture portion with an outer spherical surface and an integral anchor portion extending distally from the capture portion for fixation to the bone; a receiver comprising a base defining a cavity having a bottom opening in communication with a bottom surface of the base and a pair of integral upright arms extending upwardly from the base with interior surfaces defining an open channel configured to receive the elongate rod, the open channel being in communication with the cavity, the receiver having interior surfaces including an upper first groove and a lower second groove above the cavity; and a pressure insert having an upper surface operable to engage the elongate rod, a lower surface operable to engage the outer spherical surface of the bone anchor capture portion, and an attachment protrusion extending laterally outward from a side surface of the insert, the pressure insert undergoing placement into the receiver open channel with the attachment protrusion coming into frictional placement with the receiver upper first groove to inhibit axial movement of the pressure insert relative to the receiver, wherein, after insertion of the bone anchor capture portion into the receiver cavity through the bottom opening, the insert undergoes post-placement downward deployment within the receiver open channel by a tool coming into direct engagement against the insert, and wherein the insert attachment protrusion moves downward from the receiver upper first groove into frictional engagement with the receiver lower second groove so as to inhibit the pressure insert from moving back up within the receiver through-bore.
