The aim of this retrospective study was to analyze the results of two surgical treatments for thoracic and lumbar spinal tuberculosis.A total of 73 patients with monosegmental thoracic or lumbar spinal tuberculosis were enrolled from January 2006 to April 2011.The patients were divided into two groups.Patients in group A (n=34) underwent one-stage posterior debridement,limited decompression,bone grafting and internal fixation combined with lamina reconstruction,while those in group B (n=39) underwent one-stage posterior debridement,decompression,bone grafting and posterior instrumentation.Clinical and radiographic results were analyzed and compared between the groups.Patients were followed for a mean 31.3 months (range,21-42 months).Fusion occurred at 4-12 months (mean,7.7 months).Surgical compli-cations affected one and five patients in groups A and B,respectively.There was extraction of internal fixation in two group B patients.Postoperatively,there was significant Cobb angle correction in the two groups.By the last follow-up,the Cobb angle and correction loss in group A were significantly better than that in group B;the group A Oswestry Disability Index and Frankel grade were better than that in group B.In conclusion,one-stage posterior limited decompression,bone grafting and internal fixation combined with lamina reconstruction enables rapid management of monosegmental thoracic and lumbar spinal tuberculosis with fewer complica-tions and minimal invasion.
