Transpedicular fixation in comminuted fractures of bodies of thoracic and lumbar vertebrae

Abstract

Research Objective: improvement of transpedicular fixation technique in cases with spine injuries accompanied by vertebral body splintering. Material and Methods. Transpedicular spondylosynthesis was performed in 52 patients aged 18-49 years with comminuted fractures of thoracic and lumbar vertebral bodies. Individual peculiarities of the operation depended on the character of the injury ascertained during the preoperative examination. Standard roentgenography and computer tomography were used. Results. Lasting antalgic effect was observed in 94,2% of the operated patients. In cases with type A3 fractures according to F. Magerl the rate of the surgical correction of the pathologic posttraumatic kyphotic deformity averages 87%. Injuries classified as type A2, B2 or C2 were the indication for transpedicular os-teosynthesis by advanced techniques. Conclusion. Transpedicular spondylosynthesis is one of the effective methods of treatment of patients with comminuted fractures of thoracic and lumbar vertebral bodies, and the choice of carrying out of the procedure depends on the injury character. In cases with comminuted fractures of type A2, B2, C2 it is reasonable to perform transpedicular spondylosynthesis with introduction of the transpedicular screws into the injured vertebral body, and the technique of their use depends on the injury character.
