Systems and methods for correcting spinal deformity utilize a dynamic, multi-structure torso orthosis that allows motion during wear. The disclosed embodiments utilize a series of elastically coupled ring structures that conform to the circumference of the torso of a patient. Adjustable elastic coupling mechanisms are utilized to create and alter forces and moments that are applied to the torso through these ring structures. In some instances, the ring structures are formed from individual elements that can be linked to accommodate particular anatomies. In other instances, a superior ring structure can be configured to accommodate the patients upper torso.
