Accuracy of 3D surface scanners for clinical torso and spinal deformity assessment

Adolescent Idiopathic Scoliosis (AIS) is typically thought of as a three-dimension deformity of the spine. The severity of the deformity is assessed using the Cobb angle [1] of the spine on a posterior-anterior radiograph. The change in the patients ’ Cobb angle over time can then be used to prescribe treatments – either operative or non-operative, and to assess the effectiveness of the chosen treatment. Using only the Cobb angle however, is an overly simplistic view of this condition, with the deformity being present not only in the spine, but also in the rib cage creating a whole torso deformity.
