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 1):
A pivotal bone anchor assembly for securing an elongate rod to a bone via a closure, the bone anchor assembly comprising:\n a bone anchor having an upper end with a capture portion and an integral anchor portion extending distally from the capture portion for fixation to the bone; and a receiver assembly in a pre-assembled configuration prior to receiving the capture portion of the bone anchor, the receiver assembly including:\n 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 to define an axial through-bore, the cavity having an internal surface above the bottom opening, and the axial through-bore including an upper first recess and a lower second recess above the cavity; and \n a pressure insert having an upper surface operable to engage the elongate rod, a lower surface operable to engage the bone anchor upper end, and a ridge extending laterally outward below a top surface of the insert, the pressure insert being placed within the receiver open channel with the insert ridge disposed within the receiver upper first recess to maintain the receiver assembly in the pre-assembled configuration, \n wherein, after insertion of the bone anchor capture portion into the receiver cavity through the bottom opening, the pressure insert is configured for post-placement downward deployment within the receiver by a tool coming into direct engagement with the pressure insert, with the insert ridge moving downward from the receiver upper first recess into frictional engagement with the receiver lower second recess so as to allow engagement of the insert lower surface with the bone anchor upper end and to inhibit the pressure insert from moving back up within the receiver through-bore.
