BACKGROUND CONTEXT: In adolescent idiopathic scoliosis (AIS), identification of curve patterns and determination of fusion levels are most important for correcting deformity, improving trunk balance, and saving motion segments. Lenke 1A scoliosis is the most common type of AIS, accounting for around 16% of all AIS; however, how to determine the lower instrumented vertebrae in this common curve type is unclear.
