Abstract
A pedicle screw is provided to be inserted into and fixed to a pedicle of a spinal disease patient, and more particularly, a pedicle screw in which a screw thread of a clamp screw is formed to have dents and protrusions with trapezoid cross-sections so as to form a predetermined gap with a screw thread of a fixing unit having dents and protrusions with rectangular cross-sections when the clamp screw is combined with the fixing unit, and the screw thread of the clamp screw has different pitches to disperse an external impact so as to further firmly combine the clamp screw with the fixing unit.
