目的：总结球囊扩张椎体后突成形术治疗腰椎压缩性骨折伴后缘破裂的临床疗效。方法回顾性分析应用球囊扩张椎体后突成形术治疗腰椎压缩性骨折伴后缘破裂并获得随访3个月以上的13例患者临床资料。结果 VAS评分：术前平均（8.49±0.12）分，术后平均（2.27±0.08）分，差异有统计学意义（P＜0.01）；病椎形态变化情况：椎体中部高度术前平均（2.14±0.05）cm，术后平均（2.59±0.07）cm，差异有统计学意义（P＜0.05）；Cobb角：术前平均（22.4±2.4）°，术后平均（9.7±1.5）°，差异有统计学意义（P＜0.05）。结论球囊扩张椎体后突成形术治疗腰椎压缩性骨折伴后缘破裂止痛效果确切，椎体高度得到不同程度恢复，操作简便。“,”ObjectiveTo investigate the influence of percutaneous kyphoplasty to lumbar burst fracture. Methods We analyzed retrospectively the 13 cases of percutaneous kyphoplasty to lumbar burst fracture.Results VAS score: with an average (8.49±0.12) points preoperatively, after (2.27±0.08) points, before and after surgery were signiifcantly different (P<0.01). Morphological changes in vertebral disease: Preoperative vertebral body height to the middle with an average of (2.14±0.05) cm, after (2.59±0.07) cm, before and after surgery there was a signiifcant difference (P<0.05). Cobb angle: with an average (22.4±2.4)°preoperatively, after (9.7±1.5)°, before and after surgery were signiifcantly different (P<0.05).Conclusion Percutaneous kyphoplasty to expand the treatment of lumbar burst fracture has precise analgesic effect, and vertebral height can be restored to varying degrees, easy to operate.
