STUDY DESIGN: Single institution, retrospective cohort study of 49 consecutive patients with Lenke I adolescent idiopathic scoliosis, all operated by a single surgeon using identical surgical technique and type of instrumentation. OBJECTIVE: To evaluate the early coronal and sagittal correction of main thoracic adolescent idiopathic scoliosis using all-pedicle screw instrumentation and to determine whether implant density influences correction. SUMMARY OF BACKGROUND DATA: There is an increasing trend in the use of pedicle screws in scoliosis correction surgery, particularly in using segmental all-pedicle screw constructs. No previous studies have investigated whether higher pedicle screw imp..View full abstract
