Retrospective, comparative study.To compare the effects of anterior rod-screw instrumentation and posterior pedicle screw on sagittal balance in patients with Lenke type 5 adolescent idiopathic scoliosis (AIS).Lenke AIS is treated by or spinal fusion surgery. Most studies comparing surgery have focused assessing improvement coronal balance. Studies are lacking.The records 49 diagnosed were examined. A total 21 underwent between 2000 2003, while 26 2004 2006. Preoperative, postoperative, follow-up thoracic kyphosis (T5-T12 T2-T12), lumbar lordosis, thoracolumbar junction kyphosis, vertical axis measurements made examining radiographs. Quality life was assessed using Scoliosis Research Society-22 questionnaire. All followed up for at least 2 years.There no significant group differences alignment, T11-L2 alignment after Sagittal significantly more pronounced compared group. The segment also shorter scores higher group.Anterior solid results segments, better quality than AIS.
