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 22):
The pivotal bone anchor assembly of  claim 1 , further comprising a closure,\n wherein the closure includes a helically wound guide and advancement structure formed into an outer sidewall surface and engageable with the threaded closure-mating structure formed into the opposed inward-facing surfaces of the receiver upright arms to capture the elongate rod within the receiver open channel, and wherein the helically wound structure is configured to inhibit splaying of the receiver upright arms when the closure locks the assembly.
