Abstract

Abstract:

BACKGROUND: The effects of both conservative and traditional open reduction and internal fixation are dissatisfactory in the treatment of thoracolumbar fractures, however, minimal-invasive percutaneous pedicle screw-rod systems provide a new available method.
OBJECTIVE: To investigate the clinical effect of percutaneous pedicle screw fixation using Sextant minimal-invasive system in the treatment of thoracolumbar fractures.
METHODS: A total of 55 patients, who had undergone percutaneous pedicle screw fixation using Sextant system (25 patients) or open pedicle screw fixation (30 patients) for single-level vertebral body compression fractures in Department of Orthopedics, Renmin Hospital of Wuhan University from February 2011 to January 2013, were enrolled in this study. They showed no neurological signs and symptoms. The operative time, intraoperablood loss, postoperative drainage amount, length of hospital stay, pre- and post-operative Cobb angle and anterior vertebral body height ratio were recorded and compared between two groups.
RESULTS AND CONCLUSION: Except two patients in open pedicle screw fixation group were lost after discharge, all other patients were followed up for 8-14 months. There were significant differences in operative time, intraoperative blood loss, postoperative drainage amount and length of hospital stay between two groups (P=0.000 0). The post-operative Cobb angle was significantly lower while anterior vertebral body height ratio was significantly higher at one week than those before fixation in two groups (P=0.000 0). No significant difference was found in correction loss between two groups at 8 months after operation. Experimental findings indicate that, percutaneous pedicle screw fixation using Sextant system has a satisfactory outcome in the treatment of thoracolumbar fractures. However, understanding the correct indications is very important for clinical application.
