  • Extreme lateral channel debridement and fusion combined with posterior fixation for lumbar spinal tuberculosis

    Objective To investigate the effectiveness of extreme lateral channel debridement and fusion combined with posterior fixation for lumbar spinal tuberculosis. Methods A retrospective analysis was made on the clinical data of 17 patients with lumbar spinal tuberculosis undergoing extreme lateral channel debridement and fusion combined with posterior fixation between December 2008 and December 2014. There were 10 males and 7 females, aged 20-69 years (mean, 42.6 years). The disease duration was 1-6 months (mean, 3.4 months). The involved segments included L1, 2 in 5 patients, L2, 3 in 6 patients, L3, 4 in 3 patients, and L4, 5 in 3 patients. Based on American Spinal Injury Association (ASIA) classification, there were 2 cases of grade C, 13 cases of grade D, and 2 cases of grade E. The visual analogue scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and Barthel index were used to evaluate the effectiveness, and the improvement rate of JOA score and Barthel index was calculated at the same time. Lumbar X-ray film and CT were taken regularly to evaluate lumbar kyphotic Cobb angle correction and bony fusion. Results The operation was successfully performed in 17 patients, and pathological examination showed tuberculosis. All cases were followed up 24-48 months (mean, 35.3 months). Lumbar X-ray film and CT showed that necrotic bone and abscess were cleared completely, and lumbar kyphosis correction was satisfactorily in all cases. Bony fusion was achieved within 6 months, and clinical cure was obtained within 18 months in all cases; no recurrence was found during follow-up period. No loosening or breakage of internal fixation was observed. At last follow-up, ASIA classification was recovered to grade D and grade E from grade C in 2 cases, to grade E from grade D in 11 cases and had no change in 2 cases (grade D). Two cases of ASIA grade E showed no neurological deficit. The VAS score, JOA score, Barthel index, and lumbar kyphotic Cobb angle were significantly improved at 2 weeks after operation and at last follow-up when compared with preoperative ones (P<0.05). At last follow-up, the improvement rate of JOA score was 75.2%±6.2% and the improvement rate of Barthel index was 75.7%±10.8%. Conclusion To use extreme lateral channel debridement and fusion combined with posterior fixation is an effective treatment for lumbar spinal tuberculosis.
