Sagittal alignment of the cervical spine in adolescent idiopathic scoliosis: a comparative study of 42 adolescents with idiopathic scoliosis and 24 normal adolescents

摘要

Kyphosis of the cervical spine has been reported in patients with adolescent idiopathic scoliosis (AIS). However, few reports have compared sagittal spine alignment of AIS patients with that of the normal population. The purposes of this study were (1) to analyze the characteristics of sagittal alignment, including the cervical spine, in AIS patients with a single thoracic curve (Lenke type 1) compared with the age-matched normal population and (2) to quantify the changes in sagittal alignment of the cervical spine and thoracic kyphosis following posterior spinal fusion.
