The main purpose of this study is to review and examine the safety of pedicle screws in adolescent idiopathic scoliosis. In spite of having a greater risk for neurological injuries, the use of pedicle screws has shown higher rates of correction in scoliosis surgery. As per the reviews, there is a high-risk factor for or inserting a pedicle screw during the surgery. The surgeons need to maintain 100% accuracy and safety at the time of insertion. Some studies have been found who have reported abnormal anatomy for the pedicle screw in adolescent idiopathic scoliosis. The studies also conveyed that patients with pedicle screws in AIS have been injured many times. Even with the 25 mm shot pedicle screws, the rate of injury cannot be decreased. In different cases, aortic injury has been spotted in pedicle screw insertion in adolescent idiopathic scoliosis.

Although different studies have described pedicle screw insertion in scoliosis surgery as safe. Studies showed that the neurological adverse incidents after scoliosis surgery are just between 0.06% to 1.9%. Therefore, as per the study, despite having a chance of injury, pedicle screw insertion is being used widely in adolescent idiopathic scoliosis
