Possibilities of Transpedicular Osteosynthesis in Treatment of Thoracic and Lumbar Spine Injuries

Results of surgical treatment of 84 patients with thoracic and lumbar spine injuries using transpedicular osteosynthesis are presented. The patients were operated on within the terms from 2 days to 3.5 years after trauma. Different types of surgical reposition were used depending on the terms after injury and value of deformity. In 51 patients anterior corporodesis was performed. Average correction of local kyphosis was from 7.4° to 17.7° in different groups of patients. Vertical size of inured segments was restored up to 63.8-92%. Suggested method of intraoperative spine reposition enabled to increase the correction volume 1.7-2 times in late terms after injury. In severe deformities preliminary stage, i.e. transpedicular osteosynthesis using external fixation device with gradual correction over 35° was used. Complications - fracture of longitudinal rod (3 cases), partial destabilization of spine column in osteoporosis (2 cases), as well as loss of correction by 2-3° (9 cases) and 6-15° (3 cases) did not influence the outcomes significantly. In 48 patients the follow-up period was over 1 year. In 44 patients good results were achieved and satisfactory result was noted in 4 patients.
