COMPUTED TOMOGRAPHY AS A COMPONENT OF PREOPERATIVE PLANNING FOR METAL TRANSITIONAL SPINE FIXATION IN THE CORRECTION OF SCOLIOTIC DEFORMITIES BY HYBRID CONSTRUCTS

Abstract

Objective: to assess whether computed tomography (CT) data can be used for metal transitional spine fixation in patients with thoracic and thoracolumbar scoliosis at the stage of surgical intervention planning.Material and methods. Thirty-nine patients with grades 3 and 4 (according to V.D. Chaklin) or type I–III (according to the classification proposed by L. Lenke) thoracic and thoracolumbar idiopathic scoliosis were examined. All the patients underwent a comprehensive radiographic and CT examinations. The radiomorphometric features of the spine were used to plan surgical interventions.Results. The protocol was clarified for preoperative scoliosis examination using CT data on cervicothoracic and thoracolumbar vertebrae. A personalized approach to planning an operation on the basis of CT examination permits one to eliminate destabilization of the supporting elements of the corrective system at the most. Reducing the risk of postoperative losses of correction contributes to the use of multi-rod constructs.Conclusion. CT that enables a comprehensive assessment of existing pathology and clarification of the nature of impending surgery should be carried out in patients with thoracic and thoracolumbar idiopathic scoliosis at the stage of preoperative planning for metal transitional spine fixation.
