RESUMEN
BACKGROUND: The relationship of spinopelvic parameters with spondylolisthesis is widely explored. However, there is scarce evidence on correlation of tuberculosis of lumbar spine with respect to spinopelvic harmony. The current study aims to find the association between functional outcomes and spinopelvic parameters in lumbar spine tuberculosis treatment. METHODS: A total of 47 patients with active tuberculosis confined to lumbar spine were prospectively analyzed and divided into 2 groups according to mode of intervention. Group A included 26 operatively managed patients and group B had 21 conservatively managed cases. Functional parameters comprising Oswestry Disability Index (ODI) and Visual Analog Scale (VAS) along with spinopelvic radiologic parameters (pelvic incidence [PI], pelvic tilt [PT], sacral slope [SS], lumbar lordosis [LL], PI-LL, sagittal vertical axis) in both groups were analyzed at 0 and 6 months of follow-up. RESULTS: Both the groups showed significant improvement from initial presentation to final follow-up in ODI (Group A: 85.4 ± 12.1-12.3 ± 3.2, P = 0.02; Group B: 82.5 ± 10.06-36.8 ± 11.9, P = 0.04) and VAS (Group A: 8.1 ± 1.2-1.4 ± 0.9, P = 0.02; Group B: 8.5 ± 0.09-3.5 ± 1.1, P = 0.02). Statistically significant (P < 0.05) difference was observed in both functional outcome parameters between the 2 groups at 2-month and 6-month follow-up, compared with nonsignificant difference (P > 0.05) at presentation. Better improvements of spinopelvic parameters of PT, SS, LL, PI-LL were observed in Group A and in both groups the difference of these parameters correlated with differences of functional outcome parameters, though PI showed no correlation. CONCLUSIONS: The spinopelvic parameters played significant role in functional outcome. There is better functional outcome when LL is adequately restored. Surgical correction offered betterment of spinopelvic parameters like PT, SS, an sagittal vertical axis, which in turn leads to improvement in functional outcome.
RESUMEN
OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
