Abstract
A spinal screw assembly includes a bone-anchoring member, a washer, and a seat. The bone-anchoring member includes a main shaft, a washer head, and a spherical head. The spherical head extends upward from the top end of the main shaft and the washer head extends laterally from a location of the main shaft between the main shaft's top end and bottom end. The washer is polyaxially rotatable and positionable around the washer head and is configured to be placed at a first angle relative to the main shaft. The seat is polyaxially rotatable and positionable around the spherical head independent from the washer and is configured to be placed at a second angle relative to the main shaft, wherein the second angle is independent from the first angle.
