Surgical management for thoracic spinal tuberculosis posterior only versus anterior video-assisted thoracoscopic surgery.

Abstract

STUDY DESIGN: A comparable retrospective study. OBJECT: To compare the clinical outcomes of surgical treatment by posterior only and anterior video-assisted thoracoscopic surgery for thoracic spinal tuberculosis (TSTB). METHOD: 145 patients with TSTB treated by two different surgical procedures in our institution from June 2001 to June 2014 were studied. All cases were retrospectively analyzed and divided into two groups according to the given treatments: 75 cases (32F/43M) in group A performed single-stage posterior debridement, transforaminal thoracic interbody fusion and instrumentation, and 70 cases (30F/40M) in group B underwent anterior video-assisted thoracoscopic surgery (VATS). Clinical and radiographic results in the two groups were analyzed and compared. RESULTS: Patients in group A and B were followed up for an average of 4.6±1.8, 4.4±1.2 years, respectively. There was no statistically significant difference between groups in terms of the operation time, blood loss, bony fusion, neurological recovery and the correction angle of kyphotic deformity (P>0.05). Fewer pulmonary complications were observed in group A. Good clinical outcomes were achieved in both groups. CONCLUSIONS: Both the anterior VATS and posterior approaches can effectively treat thoracic tuberculosis. Nevertheless, the posterior approach procedure obtained less morbidity and complications than the other.
