Method of Using Spine Stabilization System With Dynamic Screw

Abstract

A method of using a spine stabilization system in one embodiment includes inserting a bone fastener shank through a receiver structure cavity and then through a distal opening of the receiver member, positioning a head of the fastener against a bearing surface of the receiver structure, positioning a bearing member on an upper portion of the head, positioning a first pivot bearing portion of a pivot member above the positioned bearing member, positioning a pivot portion of a connector assembly on the positioned first pivot bearing portion, positioning a second pivot bearing portion of the pivot member on an upper portion of the pivot portion, and threading a fixation screw into a threaded portion of the receiver structure, thereby (i) causing the pivot member to clamp the pivot portion, and (ii) clamping the head of the screw between the first bearing and the bearing surface.
