Abstract:

Objective To further evaluate the efficacy of foraminal lens combined with posterior percuta⁃ neous pedicle screw and streptomycin calcium sulfate artificial bone in the treatment of lumbar tuberculosis in the 1⁃year follow⁃up. Methods Data of fifty⁃two patients with lumbar tuberculosis who received surgical treatment in the First Affiliated Hospital of Guangxi University of Chinese Medicine from July 2016 to June 2020 were retrospec⁃ tively analyzed. The follow ⁃ up time ranged from 12 months to 20 months，with an average of（14.08 ± 1.27） months，and 50 effective cases were finally included. According to the method of operation，the patients were divided into group A（32 cases treated with foraminal lens combined with posterior percutaneous pedicle screw and streptomycin calcium sulfate artificial bone）and group B（18 cases treated with）A comparative study was conducted in terms of related indicators in the two groups. Results In the follow⁃up of 52 cases，2 cases were shed（1 case died，1 withdrew automatically），and 50 effective cases were eventually included. Comparison of age，sex，ESR， CRP，Cobb Angle，VAS，JOA，ODI score and ASIA grade between the two groups at the end of follow⁃up（P > 0.05） indicated no significant difference but comparison of operative time，intraoperative blood loss，time out of bed and length of stay between the two groups（P < 0.05）indicated statistical significance. Conclusion Compared to traditional anterior，posterior or combined anterior and posterior surgery for lumbar spinal tuberculosis，foraminal lens combined with posterior percutaneous pedicle screw and streptomycin calcium sulfate artificial bone in the treatment of lumbar tuberculosis，can also achieve satisfactory clinical effect. Streptomycin sulfate artificial bone helps to slowly release drugs and improve local drug concentration streptomycin lesions for a strong bactericidal effect. It also has the advantages of small trauma and quick recovery. In addition，it achieves the purpose of decom⁃ pression，removal of lesion tissue and reconstruction of spinal stability by bony fusion.
