Abstract: 【Abstract】〓Objective〓To investigate the efficacy of minimally invasive percutaneous pedicle screw fixation on thoracic vertebral compression fractures. Methods〓Thirty patients with thoracic vertebral compression fractures from January 2012 to November 2014 were included in the study, the data were analyzed retrospectively. Of these 30 cases, 15 underwent surgical procedure of minimally invasive percutaneous pedicle screw fixation (observation group) and 15 were treated with open surgery of traditional posterior midline longitudinal incision approach. The operation time, blood loss, hospital stay, postoperative visual analogue scale (VAS), postoperative Cobb angle correction rate, postoperative failed back surgery syndrome(FBSS) were compared between two groups. Results〓In observation group, the mean operation time, blood loss, hospital stay were significantly reduced when compared with control(P<0.05). VAS at 48 h was significantly lower in observation group than in control group(P<0.05). The postoperative Cobb angle correction rate in observation group was similar to that in control. FBSS patients in control group was higher than in the observation group, but the difference was not statistically significant. Conclusion〓Minimally invasive percutaneous pedicle screws osteosynthesis has better surgical results than the traditional posterior midline longitudinal incision approach in treatment of thoraco-lumbar vertebra fracture.
