Abstract
An apparatus for connecting vertebrae including a rod and a fastener for connecting the rod with a vertebra of a spinal column. The fastener includes a screw having a threaded portion for connection with the vertebra. The screw has a head connected to one end of the threaded portion. The head includes a bight portion and a pair of spaced apart resiliently deflectable legs extending from the bight portion. The pair of legs and the bight portion define a cavity in the screw head. The rod is receivable in the cavity in the screw head. A cap is receivable on the pair of legs and deflects the pair of legs to clamp around the portion of the rod received in the cavity in the screw head. The cap is retained on the screw so that movement of the rod relative to the screw is blocked.
