Anterior and Posterior Instrumentation with Different Debridement and Grafting Procedures for Multi-Level Contiguous Thoracic Spinal Tuberculosis.

Abstract：

OBJECTIVE:To evaluate the clinical outcomes of anterior and posterior instrumentation with different debridement and graft fusion methods for multi-level contiguous thoracic spinal tuberculosis. METHODS:We retrospectively evaluated 81 patients with multi-level contiguous thoracic spinal tuberculosis who underwent anterior or posterior instrumentation combined with different methods of debridement, decompression, and graft fusion from January 2002 to December 2012. All patients were divided into an anterior instrumentation group and a posterior instrumentation group. In the anterior instrumentation group, there were 39 patients who underwent transthoracic debridement. In the posterior instrumentation group, there were 34 patients who underwent trans-costotransverse decompression and strut grafting with posterior instrumentation, and another 8 patients underwent combined anterior debridement and strut grafting with posterior instrumentation in a single-stage or two-stage procedure. The kyphotic angles were calculated from lateral spinal X-rays using the modified Konstam method. The symptoms and signs of tuberculosis, fusion level, fusion time of the bone graft, average kyphosis angle, average correction, average loss of correction, and clinical complications were recorded. The average follow-up period was 37 months (range, 17-72 months). RESULTS:The cohort consisted of 47 males and 34 females with an average age of 38 years. The mean durations of the operations were 3.5 ± 0.4 h in the anterior group and 4.0 ± 0.3 h in the posterior group ( P < 0.05). The mean blood loss volumes during surgery were 450 ± 42 and 560 ± 51 mL for the anterior group and the posterior group, respectively ( P < 0.01). The kyphotic deformities were corrected from 32.1° ± 10.3° to 10.2° ± 2.1° in the anterior group and from 33.8° ± 11.7° to 12.6° ± 2.7° in the posterior group ( P < 0.01). The neurologic statuses of the 23 patients with preoperative neurologic deficits improved in each group. Fusion was confirmed radiographically at 5.4 ± 1.2 months (range, 4-12 months) in the anterior group and 5.6 ± 1.4 months (range, 4-13 months) in the posterior group ( P > 0.05). Postoperative relapses were noted in 1 and 3 patients in the anterior and the posterior group, respectively. CONCLUSION:Posterior instrumentation was more effective than anterior instrumentation in the correction of kyphosis and the maintenance of the correction. However, postoperative sinus formation was more frequent in patients who underwent a single-stage posterior procedure.
