Abstract
An anchor screw assembly includes a screw having a threaded portion and a head portion to which a swing bolt is pivotally coupled. A clamp assembly includes lower and upper clamp portions that are securable on the swing bolt by a fastener. The clamp portions include noncircular first passages for receiving a noncircular region of the swing bolt therethrough to prevent rotation of the clamp assembly on the swing bolt, and cooperating grooves that together define a second passage. The head portion of the screw includes a shoulder, and the lower clamp portion frictionally engages the shoulder when the clamp assembly is fully secured on the swing bolt, thereby securing the swing bolt relative to the screw. Multiple screw assemblies are screwed into adjacent vertebrae, and a rod is secured within the second passages between the anchor screw assemblies to stabilize the vertebrae.
