One-stage surgical treatment for thoracic and lumbar Spinal tuberculosis by transpedicular fixation, debridement, and combined interbody and posterior fusion via a posterior-only approach

Abstract

This study examined the clinical outcomes of one-stage surgical treatment for patients with spinal tuberculosis via a posterior-only approach. Twenty-four patients with thoracic or lumbar spinal tuberculosis whose lesions were confined to adjacent segments were admitted to our hospital and treated. The American Spinal Injury Association (ASIA) impairment scale was used to assess the neurological function. All patients were treated with one-stage surgical treatment via a posterior-only approach. The clinical efficacy was evaluated by the Japanese Orthopaedic Association (JOA) scores and oswestry disability index (ODI) of nerve function. Patients were evaluated preoperatively and postoperatively by measurement of spinal deformity using Cobb angle and radiological examination. All the patients were followed up for 13 to 27 months. They had significantly postoperative improvement in JOA score, ODI and ASIA classification scores. The kyphotic angles were significantly corrected and maintained at the final follow-up. Bone fusion was achieved within 4-12 months. It was concluded that one-stage surgical treatment via a posterior-only approach is effective and feasible for the treatment of spinal tuberculosis.
