Abstract
Objective To compare clinical effect and radiographic results of posterior monosegment or bisegmental pedicle screw for thoracolumbar burst fractures. Methods A total of 70 patients were divided into monosegmental group ( posterior monosegmental pedicle screw for thoracolumbar burst fractures, 33 cases) and bisegmental group ( posterior bisegmental pedicle screw for thoracolumbar burst fractures, 37 cases ) , according to different fixation method. These data were compared between two groups, including operative time, blood loss ( intraoperative blood loss + postoperative drainage) , hospital stay, perioperative complications, ODI at 24 months after surgery, postoper-ative vertebral height correction rate, corrected vertebral height loss rate at 24 months after surgery, postoperative Cobb angle correction rate, and Cobb angle correction loss rate at 24 months after surgery. Results All of patients were followed up for 24 months. There was no significant difference between the monosegmental group and bisegmen-tal group in hospital stay, perioperative complications, ODI at 24 months after surgery, postoperative vertebral height correction rate, and postoperative Cobb angle correction rate (P>0. 05). However, there were significant difference between the monosegmental group and bisegmental group in term of operative time, blood loss, corrected vertebral height loss rate at 24 months after surgery, and Cobb angle correction loss rate at 24 months after surgery ( P <0. 05). Conclusions Both of posterior monosegment or bisegmental pedicle screw for treatment of thoracolumbar burst fractures can achieve satisfactory clinical outcomes. The former has a less operative time and blood loss, and the latter is effective to maintain reduction and reduce the rate of correction loss.关键词
