Adolescent idiopathic scoliosis: Lenke type I-VI case studies.

Brace treatment is effective for selected patients with AIS, but when patients mature or curves progress beyond 40 degrees , surgery may be discussed with the patient and family. The advent of third-generation spinal instrumentation with pedicle screw systems has made extraordinary corrections possible. These posterior corrections must be done cautiously, however. When selecting the fusion level, one should always look at the sagittal plane and include any kyphotic segments. The authors evaluate case examples of Lenke type I through type VI curves with illustrations and radiographic images in this additional content, which is only found on-line.
