Surgical Level Selection in Adolescent Idiopathic Scoliosis: An Evidence-Based Approach.

The selection of fusion levels in the treatment of adolescent idiopathic scoliosis remains complex. The goals of surgery are to minimize the risk of future progression and optimize spinal balance while fusing the least number of levels necessary. Several classifications, rules, and algorithms exist to guide decision making, although these have previously not been easily referenced in a study. This review aims to provide an evidence-based approach of selecting fusion levels that balances the expert opinion of the authors with the current literature.
