The radiometric analysis of the chest and spine deformity following surgical treatment of idiopathic scoliosis by the C-D method.
Material and methods. A group of 61 consecutive patients with AIS treated operatively by C-D method was evaluated in order to assess the immediate postoperative changes of spinal and rib cage deformity and to determine relationships between spinal and rib hump correction. Postoperative spinal and thoracic shape changes were measured on radiograms and CTscans at apex of the curve. <br /> Results and Discussion. Statisticaly significant corrections of lateral curvature (60%), axial rotation (RAsag - 9% , RAml-18%), and rib cage deformity (RHindex- 24%) were recorded. Kyphosis changes were not significant. Axial rotation as well as rib hump increase was observed in some cases. Thoracic deformity correction in C-D method appeared to be related with translation of the apex of the curve, but in the horizontal plane this effect was negative probably due to the rigidity of the structural changes. Postoperative derotation of the curve apex seemed to influence the rib hump size reduction.
