Abstract
Background: Surgeons have been successfully handle with spinal tuberculosis via conservative or surgical treatment. However, There are quite few classifications or scoring systems concerning spinal tuberculosis to guide the surgeons to manage the complicated pattern of spinal tuberculosis. The purpose of this study is to design a practical, yet comprehensive, severity scoring system for spinal tuberculosis that helps in clinical decision-making in terms of the need for operative versus non-operative management.Methods: A group of 129 spinal tuberculosis cases (70 male and 59 female patients) successfully treated and followed up for at least 2 years were retrospectively reviewed. Clinical spine experts from our institutions were gathered to confirm the information they considered pivotal in the communication of spinal tuberculosis and the clinical decision-making process. Typical spinal tuberculosis patterns were reviewed and reconsidered in view of these essential characteristics. An initial validation process to determine the reliability and validity of this system was also undertaken. Results: A new severity scoring system was designed based on three essential characteristics: 1) the stability of spinal infectious segments determined by imaging appearance, 2) the cause of spinal cord compression and the severity of neurologic deficit, and 3) the efficacy of the anti-tuberculosis drug therapy. A severity score was calculated from these characteristics, which divided patients into surgical and nonsurgical treatment groups. Conclusions: The severity scoring system comprehensively considers features cited in the literature including prediction of spinal stability and kyphosis deformity progression, identification of neurologic compromise and characteristics of mechanical compression of spinal cord. This classification system is intended to facilitate clinical decision-making in the management of adult spinal tuberculosis (from C3 to L5 segments) . The severity scoring system may help to improve the communication among spine surgeons. Further studies are needed to determine the reliability and validity of this system.
