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 friction fit compression insert (some with lock and release feature), a planar split retaining ring and a shank upper portion cooperate 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 and the receiver and insert may include aligned tool receiving apertures for lock and release of the polyaxial mechanism.

Claim (Index 4):
The bone anchor assembly of  claim 1 , wherein a length of the insert second channel defined as the distance between outer ends of the insert opposed extensions, as measured along the transverse axis, is greater than the greatest width between inner surfaces of the insert upright arms, as measured perpendicular to both the transverse axis and the central vertical axis.
