Jung and Park: Clinical and Radiological Analysis of Thoracoscopic Spinal Surgery in Thoracolumbar Burst Fracture

Abstract

Objective

To evaluate the effectiveness and reasonability of thoracoscopic spinal surgery in patients with thoracolumbar burst fractures.

Methods

The authors reviewed the patients who had undergone thoracoscopic spine surgery for thoracolumbar burst fracture between January 2008 and October 2010. Spine lateral radiographs were taken at preoperative and follow-up periods and thoracolumbar kyphosis (T11-L2 Cobb angle) was measured. Oswestry disability index (ODI) and Visual analogue scale (VAS) scores were also measured preoperatively and follow-up.

Results

There were three male patients and 2 female patients and a mean age of patients was 51.6±14.38 years. Mean follow-up duration was 14.0±7.8 months. The mean ODI score in follow-up period was significantly improved (40±1.5 and 13±11.4, p=0.043). The difference between preoperative and follow-up mean VAS scores was significant (8±1.1 and 1±1.7, p=0.042). Mean preoperative kyphotic angle was 21.4±6.48 degree and mean follow-up kyphotic angle was 10.3±7.41 degree. There was significant difference (p=0.036). One patient complained a transient intercostal neuralgia and there was postoperative chylothorax in other patient.

Conclusion

In this study, there are good clinical and radiological results after thoracoscopic spine surgery in short-term period. Although thoracoscopic spine surgery requires a steep learning curve, it could be a promising technique with good results in thoracolumbar burst fracture.

TABLE 1
Thoracolumbar injury severity score (TLISS) system
jknts-7-24-i001

The score is the total of 3 components: injury mechanism, neurologic status, and PLC distruption. A score of ≤3 suggests nonoperative treatment, 4, operative or nonoperative treatment, and ≥5 suggests operative treatment
