Aim:Surgery is the gold standard treatment for patients with scoliosis. Fusion and reconstruction of the spinal column is the preferred method for correction of scoliosis. This study aimed to investigate the preoperative and postoperative differences in the upper-body and spinal shapes of patients with scoliosis. Material and Methods:Digitized two-dimensional X-ray images were used to obtain the shapes of the upper-body and spine. The preoperative and postoperative mean shapes were compared by using a Generalized Procrustes analysis. The thin plate spline (TPS) method was used to evaluate the spinal shape deformation between the preoperative and postoperative periods.Results:The pre- and postoperative upper-body and spinal shape differences were significant. The TPS graphics showed high-level deformations between the pre- and postoperative periods. The left superior border of the L4 spinous process showed the highest deformation.Conclusion:The preoperative and postoperative upper-body and spinal shape differences and structural deformations that correlated with scoliosis were shown to be significant.
