AB - Abstract Study Design Single-center retrospective cohort analysis. Objectives To analyze the impact of loss of global lumbar lordosis (GLL) on functional outcomes in tuberculosis of the lumbar and lumbosacral spine and to define strategies to restore or preserve the physiological lumbar lordosis. Summary of Background Data In tuberculosis of lumbosacral spine, loss of lumbar lordosis (LL) leads to altered lumbosacral biomechanics. All available studies have assessed treatment outcomes with respect to physical well-being, neurologic improvement, bone healing, and changes in radiologic parameters. None have studied the correlation between functional outcomes and LL following treatment. We reviewed 63 patients with tuberculosis of lumbar and lumbosacral spine, with an attempt to analyze the impact of loss of GLL on functional outcomes and have defined strategies to restore the same. Methods We retrospectively reviewed 63 patients with lumbar and lumbosacral tuberculosis, treated conservatively (n = 33) or surgically (n = 30) from March 2007 to July 2013. Average follow-up was 43.1±7.2 months. The correlation between posttreatment GLL and the functional outcome (Oswestry Disability Index), measured at 36 months’ follow-up, was analyzed. Results All patients showed good bone healing (at 8.4±1.5 months), significant improvement in neurology, VAS scores, ESR and CRP, p<0.001. Mean loss of GLL in the conservatively treated group was 6.4°±5.7°, whereas there was an average gain of 10.9°±9.9° of GLL with surgery. In all patients with minimal disability at the end of treatment, the final GLL was above 40°. In patients with severe disability and in a few with moderate disability, the posttreatment GLL was below 40°. Pearson’s test showed a strong negative correlation between final posttreatment GLL and the degree of disability (r = –0.867, p<0.001). Conclusions Early disease with minimal loss of lordosis can be managed conservatively, whereas in advanced disease with gross hypolordosis/kyphosis, posterior stabilization with or without global spinal reconstruction is essential to regain LL. The management of lumbosacral tuberculosis should aim at preserving or restoring the normal LL to achieve good functional outcomes. Level of Evidence Level III.
