Abstract:
A polyaxial bone screw assembly includes a threaded shank body having an integral shank head receivable in a one-piece receiver having an upper channel for receiving a longitudinal connecting member and a lower cavity cooperating with a lower opening. A compression insert (some with an independent tool lock, lock and release feature and/or friction fit feature) and a split retaining ring articulatable with respect to both the shank head and the receiver (prior to locking) cooperate with the receiver 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.

Claim (Index 1):
A pivotal bone anchor assembly for securing an elongate rode to a bone anchor via an insert compressing tool, the pivotal bone anchor assembly comprising:\n a receiver having a base defining a cavity communicating with a bottom opening, and a pair of upright arms extending upwardly from the base to define an open channel for receiving the elongate rod, the open channel communicating with the cavity to define a central bore for receiving a capture portion of the bone anchor, the pair of upright arms including opposed inward-facing surfaces having a threaded closure-mating structure formed therein and outward-facing surfaces opposite the inward-facing surfaces; and a compression insert at least partially disposed within the receiver central bore and having an upwardly facing surface configured for engagement with the elongate rod, the insert having a central opening and tool engagement structures positioned outward from the central opening, wherein after the capture portion of the bone anchor is received within the receiver cavity, and prior to or with the elongate rod being positioned within the receiver open channel in a non-locked arrangement, the insert tool engagement structures are configured for direct engagement by the insert compressing tool to receive a continuously-applied downwardly-directed force that drives the compression insert against the bone anchor capture portion, so as to temporarily lock a position of the bone anchor with respect to the receiver prior to the elongate rod being secured within the receiver open channel in a locked arrangement.
