Mini-open anterior approach focal cleaning combined with posterior internal fixation for thoracolumbar tuberculosis: Follow-up of 149 cases

Abstract

To investigate the clinical efficacy and safety of mini-open anterior approach focal cleaning combined with posterior internal fixation for thoracolumbar tuberculosis. A total of 149 patients with thoracolumbar tuberculosis were reviewed retrospectively and divided into 3 groups: mini-open anterior approach (group A), conventional anterior extraperitoneal approach (group B), and posterior approach (group C). After the operation, drainage tubes were routinely placed and the draining fluid was collected on the 4th day for the PCR detection of Mycobacterium tuberculosis (MTB), Mycobacterium tuberculosis DNA test (MTD), and Roche culture. Patients' surgical information, Cobb's angles, and postoperative complications were also compared. There was no significant difference in operation time, blood loss, hospital stay, or preoperative Cobb's angle among three groups. There existed obvious differences in the postoperative Cobb's angle and incidence of postoperative complications between group A and group C, as well as group B and group C. There was no obvious difference in the positive rate of MTB among the three groups by rapid culture plus Roche culture test. However, statistically significant differences in the positive rate of MTB were found between group A and group C by PCR detection, and between group A and group B by MTD. Mini-open anterior approach focal cleaning combined with posterior internal fixation resulted in small Cobb's angles, low incidence of postoperative complications and low positive rates of MTB, without increasing operation time, blood loss and hospital stay, rendering it as a safe and effective method to treat patients with thoracolumbar tuberculosis.
