A screw anchor assembly used in pedicle screw fixation is provided. The screw anchor assembly includes a screw having screw threads defined on a circumferential surface, and a screw anchor having a first end and a second end, an accommodating part defined by anchor screw threads on an inner surface of the screw anchor and having one end to receive the screw, and a locking step extended in a circumferential direction from the first end of the screw anchor. The accommodating part flexibly extends when the screw is screw-coupled to the screw anchor.
