Abstract


Complex evaluation of scoliotic deformity was performed using CT. Fifty patients with displastic scoliosis of III-IV degree were examined before and after surgical intervention - dorsal correction and spine fixation with Cotrel-Dubousset instrumentation. No marked derotation of spine at the deformity apex was noted postoperatively. Changes of thorax in the plane of apical vertebra were studied and quantitatively evaluated: postoperatively thorax became of more correct oval shape in all cases. Density of trabecular bone of apical and neutral vertebrae coincided with the understanding about asymmetry of deformed vertebrae bone density. No marked immediate postoperative changes were noted. Combination of CT and myelography showed the dislocation ofdural sac to the side opposite to the deformity convexity; either partial (up to 60- 70% in patients with deformity of HI and early W degree) or complete (in patients with severe deformity) disturbance of contrast distribution in subarachnoidal space from concave side and compensatory widening of subarachnoidal space from the opposite side with maximum changes at the apex of scoliotic deformity
