Impact Factors on Posterior Modified Transfacet Debridement for Thoracic Spinal Tuberculosis Basing on Regression and Classification Analysis

الملخص EN

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.
