ABSTRACT
BACKGROUND: Previous studies have indicated that correction of an established kyphosis in spine tuberculosis is both difficult and hazardous. There has not been any publication about evaluation of surgical correction of spine tuberculosis in Indonesia, despite of high incidence of spine tuberculosis cases. Therefore, we evaluated the outcome of kyphotic angle correction and neurological status after surgery of spinal tuberculosis patients for better understanding. METHODS: Retrospectively, 96 patients with spinal tuberculosis that underwent operation in Soeharso Orthopedic Hospital from June 2016 to July 2019 were selected. Operation procedure includes laminectomy, debridement and posterior stabilization. We obtained plain x-ray of spine to evaluate the kyphotic deformity before and after surgery. We also examined neurological status of the patient before and after surgery. RESULTS: The average pretreatment kyphotic angle in thoracic tuberculosis was 33.69° (range 8°-86°), which improved into a significant change to 13.27° (range 0°-56°). Correction angle was <25° in 34 people, 25°-50° in 17 people, and >50° in 4 people. While in the lumbar tuberculosis, it was 25.52° (range 6°-80°), and improved into 11.51° (range 2°-48°). Correction angle was <25° in 35 people, 25°-50° in 4 people, and >50° in 2 people. Improved neurological deficit was shown in 12% of patient with lumbar tuberculosis, and the rest had constant neurological deficit. While in thoracic tuberculosis found that 7% have improved neurological deficit and the rest is constant. None of them have worsen neurological status after the surgery. CONCLUSIONS: Surgical treatment for kyphotic deformity in patient with thoracolumbar tuberculosis are effective and safe, even in high corrective angle (>50°).
