Currently, there exist numerous orthotic options used all over the world in the conservative management of adolescent idiopathic scoliosis. A common denominator among this group is their rigid nature and limitation on spine motion. Each TLSO also implements some degree of increased intra-abdominal pressure in order to decrease the axial load on the spine for the corrective forces to be effective. Literature on the conservative management of adolescent idiopathic scoliosis is reviewed to determine the biomechanics and effectiveness of current treatments.Seven patients are reviewed who have been wearing the Spinecor orthosis to determine its effectiveness against the progression of scoliosis in the immature spine. The Spinecor is also compared with existing protocols to determine their differences biomechanically.This article examines a new concept for the conservative management of adolescent idiopathic scoliosis in order to introduce new concepts of flexibility and the absence of intra-abdominal pressure in the orthosis.
