Healing Assessment of Spinal Tuberculosis: A Systematic Review

Deciding the healing end point in spinal tuberculosis (STB) remains a controversial topic. The current systematic review aims to address the controversy existing in the literature to find a comprehensive method to assess healing in STB.A thorough literature search was carried out for studies with the assessment of healing parameters in STB. Data extraction was carried out manually, which included study characteristics and healing criteria evaluated in each study.Qualitative analysis of 8 included studies showed that healing parameters were described in 3 domains: clinical, hematologic, and radiologic response of the patient to antitubercular chemotherapy. Each domain included various individual parameters, with clinical and radiologic assessment criteria being used in most of the studies. Improvement in terms of pain, constitutional symptoms, weight gain, neurology; variation in erythrocyte sedimentation rate and C-reactive protein; and changes in radiography, magnetic resonance imaging, and positron emission tomography/computed tomography were found to be promising predictors in the assessment of healing.Radiologic response parameters emerged as the maximally used criteria to assess healing in STB. However, in the absence of any statistical analysis and an observed lag in radiologic response, the cumulative effect of all the parameters in 3 domains (clinical, hematologic, and radiologic) can be used to declare a spinal tubercular lesion nonhealing, healing, or healed.
