Abstract
A method of assembling a pivotal bone anchor assembly includes loading an insert into a central bore of a receiver, with the receiver having the central bore extending upward from a bottom opening to and through a first channel for receiving a rod, and the insert having an upper portion defining a second channel, opposite lateral protrusions extending outwardly in a direction transverse to the second channel, a lower collet portion, and a center opening. The method also includes positioning the insert into the central bore with the opposite lateral protrusions located adjacent to and above interference abutment surfaces formed into the central bore, and positioning a load ring within the center opening of the insert. The method further includes uploading a shank head into the central bore of the receiver through the bottom opening, capturing the shank head within the lower collet portion of the insert, and then forcibly downward displacing the insert within the central bore with the tooling so as to move the opposite lateral protrusions below the interference abutment surfaces.
