Abstract
This paper describes new optical method and software tool developed to extract important intrinsic indicators of adolescent idiopathic scoliosis (AIS) non-invasively. Using optical digitalization, we scanned dorsal surfaces of 372 patients (141 males and 231 females) in a clinical environment from 2014–2017. Patient datasets were processed using our in-house “ScolioSIM” tool to generate key deformity indicators, along with 3D deformity visualizations. This method relies on a digitalized dorsal surface of AIS patient, on a multiscale and registerable 3D generic spinal model, CAD and KAx technologies. In this paper we focused our attention towards transpositions of intervertebral disks and their centroids in anteroposterior plane (AP). By knowing the exact transpositions values of all intervertebral centroids (L5/L4 to T1/C7) from the local spinal axis (DM-C7) it is possible to model 3D middle spinal alignment and to calculate the range of AIS curvature which is a basic for a new 3D classification scheme.
