Abstract
Posterior transfacet approach has been proved to be a safe and effective access to treat thoracic disc herniation. However, the influencing factors of posterior modified transarticular debridement for thoracic tuberculosis have not been reported in the clinical literature. From 2009 to 2014, 37 patients with TST underwent a posterior modified transfacet debridement, interbody fusion following posterior instrumentation, under the cover of 18 months of antituberculosis chemotherapy. The patients were evaluated preoperatively and postoperatively in terms of Frankel Grade, visual analog scale (VAS) pain score, kyphotic Cobb angle, and bone fusion. Blood loss (positive correlation) and focal debridement (positive correlation) could affect operative time. Operative time (positive correlation) could affect blood loss. While, age (positive correlation), PostE (negative correlation), and T_FocalDebridement (positive correlation) could affect bone fusion. The accuracy of naive bayes classifier model is 86.11%. Our preliminary results show that blood loss and focal debridement could affect operative time; operative time could affect blood loss; age, PostE, and T_FocalDebridement could affect bone fusion; the naive Bayes classifier model can predict the KirkaldyWillis accurately.
Highlights
Tuberculosis (TB), an infectious disease caused by mycobacterium tuberculosis (MTB), is the ninth leading cause of global death, ranking above acquired immune deficiency syndrome (AIDS). e spine is the most frequently involved part of extrapulmonary tuberculosis, which is more common in thoracolumbar vertebrae, 30.3% to 55.8% of which are thoracic tuberculosis and about 67% of thoracic tuberculosis patients are accompanied by tuberculosis [1, 2]
Vertebral body destruction will lead to spinal instability, spinal cord damage, and deformity. erefore, in addition to standardized antituberculosis treatment, surgery is an important treatment method for thoracic tuberculosis treatment [3]
We find that blood loss and focal debridement could affect operative time, but not bone fusion, gender, PreA, PostA, FFUA, age, hospital stay, segments, follow-up, PreK, PostK, PreE, PostE, FUUK, FFUE, and T_Level
Summary
Tuberculosis (TB), an infectious disease caused by mycobacterium tuberculosis (MTB), is the ninth leading cause of global death, ranking above acquired immune deficiency syndrome (AIDS). e spine is the most frequently involved part of extrapulmonary tuberculosis, which is more common in thoracolumbar vertebrae, 30.3% to 55.8% of which are thoracic tuberculosis and about 67% of thoracic tuberculosis patients are accompanied by tuberculosis [1, 2]. Erefore, in addition to standardized antituberculosis treatment, surgery is an important treatment method for thoracic tuberculosis treatment [3]. As an important surgical intervention in the treatment of spinal tuberculosis, surgical treatment aims to effectively remove the lesion, completely relieve the neurospinal compression, restore the height of the affected vertebra as far as possible, and rebuild the stability of the spine. (2) Combined approach: both lesion clearance and deformity correction. Posterior approach can better correct kyphosis, which is the most common complication of TST [7]. In terms of operation time, the combined approach was longer than the anterior approach, but there was no statistical difference with the posterior approach. In terms of blood loss, anterior and posterior combined approaches were more common than anterior or posterior approaches. In terms of blood loss, anterior and posterior combined approaches were more common than anterior or posterior approaches. ere was no clinical literature to report the influencing factors of posterior modified transarticular debridement for thoracic tuberculosis. is paper considers the influencing factors of operative time, blood loss, bone fusion, and the classification of the KirkaldyWillis
