PurposeThe combined spine and rib cage deformity in scoliosis is best described as a thoracic deformity, and recent advances in imaging have enabled better definition of three-dimensional (3D) deformity of the thorax in scoliosis. However, a comprehensive report that summarizes the published thorax deformity quantification parameter studies is lacking in the orthopaedic literature.MethodsAn extensive literature review on the quantification of thorax deformity was performed, and a total of 25 thorax deformity parameters were compiled into eight independent categories based on their similarities of deformity assessment.ResultsThis review serves as the first comprehensive summary of radiographic and CT-based thorax deformity quantification measures.ConclusionsFuture work on the complex relationships between spine and ribcage deformity and the relationship with pulmonary function could help improve clinical interventions for scoliosis treatment.
