ABSTRACT

Objective:To determine the clinical efficacy of posterior intervertebral surgery for single-segment thoracolumbar spinal tuberculosis.Methods:Clinical data were retrospectively analyzed in 62 patients with thoracolumbar spinal tuberculosis who underwent posterior intervertebral surgery (A group) or posterior and anterior combined intervertebral surgery (B group) from January 2010 to January 2015 in Department of Spinal Surgery,General Hospital,Ningxia Medical University.The operative time,blood loss,length of hospital stay,erythrocyte sedimentation rate (ESR),C-reactive protein (CRP) level,neurological function,VAS score,vertebral Cobb angle,bone healing,and postoperative complications were compared between the 2 groups.Results:All patients were followed up for 10 to 30 (average 22) months after the operation.In the A group,operative time,blood loss,and hospital stay were less than those in the B group (P＜0.05).In the follow-up,the pain of patients was alleviated and nervous function was improved obviously in the 2 groups compared with pre-operation.The ESR and CRP at the 6 months after operation returned to the normal range in patients of the 2 groups.There were significant differences in the ESR and CRP among the pre-operation,the 6 months after operation,and the end of follow-up within the group (P＜0.05),while there were no significant differences in ESR and CRP between the 6 months after operation and the end of follow-up (P＞0.05).There were no significant differences in the ESR and CRP among the pre-operation,the 6 months after operation,and the end of follow-up in the 2 group (P＞0.05).The Cobb angles after the operation and the end of follow-up were significanthy smaller than those before the operation (P＜0.01),while there were no significant differences in Cobb angle before operation,after the operation,and the end of follow-up between the 2 groups (P＞0.05).There were no significant differences in the bone healing rate at 6 months or 1 year after operation between the A group and B group (P＞0.05) and the complication rate of the A group was lower than the B group (P＜0.01).Conclusion:Clinical efficacy of posterior intervertebral surgery is satisfatory in treating single-segment thoracolumbar spinal tuberculosis with less complications.
