The invention discloses a pedicle screw implantation method. The pedicle screw implantation method comprises the following steps of 1) assembling an angle control tool; 2) printing a guide plate and a vertebral body 3D model; and 3) implanting a screw by combining an angle control combined pedicle screw implantation tool with the guide plate, clinging the guide plate to the rear edge of a pedicle, adjusting two mutually vertical angle gauges to enable the numerical values on the angle gauges to be the same as CT measurement numerical values of a preoperative vertebral body, and opening along a guide plate hole and opening a path to establish a screw path; and then removing the guide plate, and implanting the pedicle screw. The problems that in the pedicle screw implantation process, a screw feeding point is difficult to determine, and the controllability of the screw feeding direction is poor are solved; the screw implantation accuracy is improved, the operation time is shortened, the ray exposure of an operator and a patient in the operation is reduced, and the injury risks of nerves, blood vessels, spinal cord and the like are reduced; and the operation cost is reduced, the nail implantation difficulty of an operator is reduced, and wide development of medical units at all levels such as cities and counties is facilitated.
