新型脊柱外固定器联合椎体成形术治疗胸腰椎骨折

Treating the thoracolumbar fracture with the New Percutanous External Spinal Fixation combined vertebroplasty

【目的】探讨新型脊柱外固定器联合椎体成形术(PVP)治疗胸腰椎骨折的临床疗效。【方法】应用新型脊柱外固定器联合PVP治疗32例胸腰椎骨折,回顾性分析患者的临床资料,评价其手术安全性、临床疗效。【结果】所有病例椎弓根螺钉置钉及安装均成功。12例行伤椎注射磷酸钙骨水泥(CPC),20例行伤椎注射聚甲基丙烯酸甲酯(PMMA);均匀充填17例,部分充填9例,其中CPC/PMMA不同程度渗漏11例。VAS疼痛评分由术前平均8.4分恢复到术后平均2.0分(P<0.001)。伤椎cobb角由术前平均30.7°恢复到术后平均11.2°(P<0.01)。伤椎前缘高度与正常椎体比值由术前平均53.57%恢复到术后平均96.70%(P<0.001)。无严重并发症。【结论】新型脊柱外固定器联合PVP治疗胸腰椎骨折效果良好,值得临床推广应用。

[Objective]To evaluate clinical effect of treating the thoracolumbar fracture with the New Percutanous External Spinal Fixation combined vertebroplasty. [Methods]Thirty-two patients suffered thoracolumbar fractures were treated by the new percutanous external spinal fixation combined vertebroplasty Analyses by retrospect of clinical material and outcome were made, [Results]Percutanous pedicle screws implant of all cases were successed. Vertebrae of 12 cases were enhanced by calciumphosphate cement. 14 cases enhanced by polymethyl methacrylate. There was leakage of calciumphosphate cement/polymethyl methacrylate in 11 cases. Preoperative value of Cobb reduced from 30.7 to 11.2（average） （ P〈0.01）. The front hight of vertebrae restored from 53.57 to 96. 70 （ P〈0. 001）. [Conclusion]The new percutanous external spinal fixation combined percutanous vertebroplasty is an effective method for treating thoracolumbar frature.
