FRACTURES AND DISLOCATIONS OF THE THORACIC SPINE. TREATMENT WITH POSTERIOR STABILIZATION AND DECOMPRESSION.

Abstract

PURPOSE: To record our experience in surgical treatment of thoracic spine fractures with posterior stabilization, decompression and ligamentotaxis.

MATERIALS AND METHODS: From January 2000 until July 2006, 67 patients (48 males and 19 females), aged 16 to 85 years old (average 41,2 y.o) were surgically treated in our department due to thoracic spine fractures. Preoperative X-Ray and CT scan were used in all cases while in most of the cases we performed MRI to further evaluate the damage. In all cases we performed decompression and posterior stabilization using four different hardware types and whenever possible ligamentotaxis. Continuous electrophysiological monitoring was alo ued in all operations. We recorded the pre- and postoperative neurological status, the vertebral height loss, the kyphotic angle and spinal canal occupation. Moreover we recorded the average hospitalization time, the transfusion needs as well as major and minor complications. At the follow-up we measured the loss of correction at 3, 6 and 12 months postoperatively. The follow up ranged from 4 to 48 months.

RESULTS: Neurological damage was recorded in 43 % of the patients. The average preoperative kyphotic angle was 38.2° while the average spinal canal occupation was 29.8 %. The immediate postoperative correction was 16.7 °. During the follow-up we observed small, insignificant loss of correction. There were no major complications.

CONCLUSION: In cases of thoracic spine fractures the surgical treatment with posterior stabilization and ligamentotaxis is offering significant stability and adequate long term results.
