Abstract: Disclosed is a pedicle screw used in spinal fusion surgery and a device for injecting bone cement into a spine having low bone mineral density by using a pedicle screw so as to enhance strength of the spine. The pedicle screw includes a screw rod fixedly inserted into a bone, a head section provided at an upper portion of the screw rod and formed at an inner portion thereof with a U-shaped recess and a screw part, and a coupling section coupled with the screw part of the head section. The coupling section is coupled with a rod support section including a bolt having a screw structure provided at an upper portion of the rod support section, a reverse U-shaped recess formed at a lower portion of the rod support section, and a pair of protrusions provided at lateral portions of the rod support section. The screw part of the head section is formed with a pair of guide slots.
