description

This paper presents preliminary results on non-invasive optical diagnosis of patient with adolescent idiopathic scoliosis (AIS) with recently developed tool ScolioSIM. This tool generates intrinsic and extrinsic indicators of the spinal deformity and 3D CAD (Computer-aided Design) deformity model based only on a digitalized dorsal surface of the examined patient. Our primary focus in this paper are absolute axial rotations (AAR) of each vertebra in AIS patients and their correlations. Clinical relevance of this research is high, as we intend to avoid traditional methods which rely on highly complicated reading and measuring of AARs on planar x-ray films, as these methods involve ionizing radiation and require highly experienced observers. Here we demonstrated a good correlation of AARs in 372 patients optically diagnosed, and currently we perform final verification of presented method and generic CAD model of the spine against 200 low-dose EOS scans of AIS patients.
