摘要
目的探讨胸腰椎骨折经椎弓根内固定治疗中的常见并发症产生原因和处理对策。方法对156例胸腰椎骨折患者进行后路椎弓根内固定术。结果156例患者随访6～36个月,术后发生断钉6例,连接棒松脱1例,螺钉松动1例,感染1例。Frankel评分:术前A级10例,术后未恢复5例,恢复至B级2例,C级3例;术前B级7例,恢复至C级3例,D级4例;术前C级6例,恢复至D级3例,E级3例;术前D级2例,均恢复至E级。椎体前沿平均高度术前45%,术后92%;Cobb角术前平均20°,术后平均4°。结论熟练掌握胸腰椎骨折椎弓根固定操作技术,可避免大多数并发症,有利于恢复神经功能和生理曲度。
Objective To study the causes and clinical treatment of complication for thoracolumbar fracture with transpedicle screws fixation. Methods 156 cases of thoracolumbar fractures were treated with posterior transpedicle screws fixation. Results All cases were followed up for 6 -36 months. Of the 156 cases, pedicle screws broke in 6 cases, loosed in 1 cases, connective rod loosed in 1 cases, infection occurred in 1 case. The Frankel grade was im- proved 1 grade in 2 of 10 cases of Frankel A,2 grade in 3 of Frankel A, 1 grade in 3 of 7 cases of Frankel B,2 grade in 4 of Frankel B, 1 grade in 3 of 6 cases of Frankel C,2 grade in 3 of Frankel C. Complete recovery of neural function was achieved in 2 cases of Frankel D. The intervertebral height of the fractured vertebral body increased from preoperative 45% to postoperative 92% on average. The kyphosis angle increased from preoperative 20° to postoperative 4°on average. Conclusions Most complication can be avoided if well fixation technique of thoracolumbar fracture is mastered, which helps physiologic postural contour restoration and facilitates neural recovery.
