Evaluation of the Outcome of Transpedicular Fixation for Thoracic and Lumbar Tuberculous Spine Disease

Abstract

Objective: Pakistan stands sixth in countries, contributing 60% of new TB cases worldwide. TB can involve a wide variety of organs including the spine which at times need neurosurgical intervention. This study aims to determine the overall clinical and radiological outcomes in patients with dorsolumbar spine TB managed by posterior transpedicular screw fixation. The study focused to evaluate the outcome of transpedicular screws fixation for the thoracic and lumbar tuberculous spine. Materials and Methods: The study included a total of 60 patients were observed. A complete history and systemic physical examination was done. Pre-operative anteroposterior and lateral view radiographs were taken to measure the height of the vertebral body, kyphotic angulation, and sagittal plane index. Short-segment transpedicular fixation was done under general anesthesia by consultant neurosurgeons. All patients were asked for follow-up after one month. Post-operative anteroposterior plus lateral view radiographs were done to measure the height of the vertebral body, kyphotic angulation, and sagittal index. Results: In our study mean age was 47 years. 58%patients were males and 42% of patients were female. The mean postoperative vertebral height was 18.93 mm ± 1.17 and the mean postoperative Kyphotic angle was 9.68 degree ± 4.03º. The mean postoperative Sagittal index was 5.83 ± 4.55. Conclusion: The outcome of transpedicular fixation of vertebral height was 18.93 mm ± 1.17, Kyphotic angle was 9.68 degree ± 4.03º) and Sagittal index was (5.83 ± 4.55) for thoracic & lumbar tuberculous spine.
