Evaluation of the efficacy of OLIF combined posterior internal fixation for single-segment lumbar tuberculosis: a single-center retrospective cohort study

Objective To evaluate the clinical efficacy of oblique lateral interbody fusion (OLIF) combined posterior fixation for single-segment lumbar tuberculosis (TB). Methods The medical records of spinal TB patients who were admitted to our department from January 2016 to December 2018 were retrospectively reviewed, and those meeting the inclusion criteria were finally included for analysis. The operative time, operative blood loss, hospital stay, visual analogue scale (VAS) score, Oswestry disability index (ODI), Cobb angle of surgical segment, bone graft fusion rate, erythrocytic sedimentation rate (ESR), C-reactive protein (CRP), neurological function (ASIA grade) and complications of the included patients were all recorded and analyzed. Results Thirty-nine patients with lumbar TB were finally included. The mean operative time, operative blood loss, and hospital stay were 135.8 ± 19.2 min, 239.4 ± 84.7 ml, and 9.5 ± 2.7 days, respectively. The mean follow-up time was 26.3 ± 7.5 months. During the follow-up, both VAS score and ODI were significantly improved at 1 month, 3 months, 6 months, 1 year postoperative, and the last follow-up, compared with preoperative (P Conclusions OLIF combined posterior internal fixation is safe and effective in the treatment of single-segment lumbar TB, with satisfactory pain relief, improvement of lumbar and neurological function, and deformity correction.
