One-stage posterior surgical treatment for lumbosacral tuberculosis with major vertebral body loss and kyphosis.

The treatment goals of tuberculous spondylitis are to eradicate infection and to prevent or treat instability, deformity, and neurologic deficit. The purpose of this study was to evaluate the clinical outcomes following chemotherapy with 1-stage posterior debridement, correction, and instrumentation and fusion for the treatment of lumbosacral tuberculosis with major vertebral body loss and kyphosis. Fourteen patients with lumbosacral tuberculosis with major vertebral body loss and kyphosis underwent 1-stage posterior surgery. Clinical assessments included low back ache, Oswestry Disability Index, Scoliosis Research Society-22 scores, neurologic deficit, erythrocyte sedimentation rate, and C-reactive protein level. Radiographic parameters included kyphosis angle, anteroposterior translation, local scoliosis, lumbar lordosis, pelvic parameters, sagittal offset, and fusion. Thorough debridement was performed. Patients were followed for an average of 39.3 months. Constitutional symptoms, low back ache, and functional outcome improved in all patients postoperatively. At final follow-up, Frankel Grade improved by 0 to 2 grades, mean kyphosis angle improvement was 44.3°, and satisfactory spinopelvic and sagittal balance were achieved. Spinal posterolateral fusion was obtained in all patients and no fixation loosening was found at 2-year follow-up. Differences existed between the pre- and postoperative radiographic parameters (P<.05). Correction loss at last follow-up was not statistically significant (P>.05). No surgical complications or infection recurrence occurred. Tuberculosis can be cured and effective correction of kyphosis can be achieved for lumbosacral tuberculosis with major vertebral body loss and kyphosis by performing 1-stage posterior surgery and chemotherapy.
