摘要： Disclosed is a multi-axial spinal pedicle screw engaged with a spinal rod and inserted into and fixed to a pedicle. The multi-axial spinal pedicle screw includes: a screw rod in which a spherical articulation is integrally formed at an upper portion thereof, the screw rod being inserted into and fixed to the pedicle through a screw thread formed on the outer surface of a lower portion thereof; a spherical chuck having a plurality of claws, for surrounding and fixing the spherical articulation; a head section in which a receiving hole for receiving the spherical chuck fixing the spherical articulation is formed at a lower portion thereof so as to penetrate the lower portion, a rod receiving channel for receiving the spinal rod is opened upward, and an engagement screw root is formed on the inner surface of the rod receiving channel; and a tightening screw in which an engagement screw thread corresponding to the engagement screw root is formed on the outer surface thereof, the tightening screw being engaged with the head section through the rod receiving channel to fix the spinal rod.
