单侧椎弓根入路椎体后突成形术治疗椎体压缩性骨折

目的总结局麻下单侧经椎弓根入路椎体后突成形术治疗各种椎体压缩性骨折的效果和安全性。方法 2005年9月～2010年5月采用单侧椎弓根入路治疗各种脊椎压缩性骨折121例共145椎,包括老年性骨质疏松症,椎体转移性肿瘤等。所有手术均为局部麻醉、单侧椎弓根入路、术中监测生命体征、下肢感觉运动状况以及椎体复位、骨水泥弥散情况。评估术前、术后患者疼痛改善程度。结果 121例患者手术均顺利完成,术后48小时内疼痛均有不同程度的缓解。椎体前缘的高度恢复幅度平均为4±1.1mm,疼痛视觉模拟评分从术前平均7.8分改善为术后平均3.2分（〈0.05）。结论局麻下单侧经椎弓根入路椎体后突成形术治疗椎体压缩性骨折操作简单,具有较好的安全性和临床效果。

Unilateral pedicle approach Kyphoplasty treatment for vertebral compression fractures

Objective To summarize the efficacy and safety by unilateral pedicle approach kyphoplasty treatment of vertebral compression.Methods From Sept 2005 to May 2010,145 vertebra in 121 cases including senile osteoporosis and vertebral metastases were treated by Kyphoplasty.All operations were local anesthesia,unilateral pedicle approach,intraoperative X-ray,vital signs,lower extremity sensor and motor monitoring and in the procedure we observed the height of the compressed vertebrae and the diffusion of bone cement.We assessed the preoperative and postoperative the VAS（Visual analog scale） of all the patients.Results 121 operations were successfully completed,all the patients felt better within postoperative 48 hours.The recovery of the vertebral height averaged 4？.1mm and the Visual analog scale score was improved from 7.8 preoperatively to 3.2 postoperatively（P 0.05）.Conclusion Unilateral pedicle approach kyphoplasty under local anesthesia is safe and good clinical efficacy and the operation is simple.
