Abstract:
A polyaxial bone screw assembly includes a threaded shank body having an integral upper portion receivable in an integral receiver, the receiver having an upper channel for receiving a longitudinal connecting member and a lower cavity cooperating with a lower opening. A down-loadable compression insert has a lower friction fit collet and an outer receiver press fit surface. A down-loadable retaining ring has at least one inner edge and outer tiered surfaces. The ring cooperates with the shank 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. The shank and receiver once assembled cannot be disassembled. A uni-planar assembly is included.

Claim (Index 26):
The uniplanar bone anchor assembly of  claim 24 , further comprising a closure top, and wherein when the assembly is locked by the closure top, the pressure insert remains spaced apart from the flat planar outer surface portion on the at least one side of the shank head.
