Abstract:
A polyaxial bone screw assembly includes a threaded shank body having an upper portion, a receiver, a compression insert and an articulation structure made from at least two discrete pieces. The shank upper portion cooperates with the compression insert to place the retainer in frictional engagement with the receiver. The geometry of the retainer structure pieces corresponds and cooperates with the external geometry of the shank upper portion to frictionally envelope the retainer structure between the capture structure and an internal surface defining a cavity of the receiver.

Claim (Index 12):
The pivotal bone anchor assembly of  claim 1 , wherein the insert is operable to transfer the downwardly-directed force from the elongate rod to the two-part retainer to lock the angular orientation of the bone anchor with respect to the receiver.
