Does 3D back contour changes following spinal fusion in children with idiopathic scoliosis? John Thometz*, Xuecheng Liu, Channing Tassone From 11th International Conference on Conservative Management of Spinal Deformities - SOSORT 2014 Annual Meeting Wiesbaden, Germany. 8-10 May 2014 Background Oftentimes, patients find trunk asymmetry, including thoracic rib hump, shoulder level difference, more troubling than a significant Cobb angle, as topographical deformity can be readily visualized. Evaluating improvement in these back contour parameters lends to additional criteria by which to assess post-surgical improvement. Quantec raster stereography is recognized as an accurate and reliable tool for monitoring threedimensional back contour in patients with idiopathic scoliosis before and after surgery. Aims To investigate the 3D back contour changes in adolescent idiopathic scoliotic deformity from surgical intervention using Quantec imaging. Design In this prospective controlled study, 35 patients undergoing anterior and/or posterior spinal fusion were evaluated pre and post-operatively by Quantec Spinal Imaging System and radiography. Methods Mean age of patients 14.5 years, with mean follow-up duration 1.7 years. A reliable Quantec protocol was established previously in the literature, consisting of twelve parameters. Pre and post-operative parameters were analyzed by paired t-test evaluating the effects of spinal fusion on scoliosis deformity. Results Significant improvement was seen in thoracic Cobb angle from 52.9 to 19.6 degrees (p
