球囊扩张椎体成形术治疗老年胸腰椎多发性压缩骨折

Balloon kyphoplasty in treating elderly patients with multiple vertebral body compression fracture

目的探讨一次多椎体球囊扩张椎体成形术治疗老年胸腰椎多发性压缩骨折的临床疗效。方法应用一次多椎体球囊扩张椎体成形术,先扩张症状最严重椎体,再同时用球囊扩张其余椎体,恢复椎体部分或全部高度,每个椎体注入骨水泥3～8ml,术后行X线检查以评价椎体高度恢复、骨水泥填充情况及有无渗漏。疗效判断采用测类比评分法(VAS)计算患者的疼痛缓解率。结果 48例均经3～24个月的随访(平均13个月),疼痛缓解率平均为86.2%。术后X线片显示骨水泥在椎管内充填满意,椎体高度平均恢复达到60%～80%,前屈后伸未见椎体前缘高度改变。结论一次多椎体球囊扩张椎体成形术微创、止痛效果好,疗效明显,是治疗老年胸腰椎多发性压缩骨折的有效方法。

Objective To analyze the clinical effects of balloon kyphoplasty in treating elderly patients with multiple vertebral body compression fracture. Methods Firstly,multi-vertebral balloon kyphoplasty was performed on the most serious part,when expand the other parts,and recover the part or all heights of vertebral body.The bone cement was injected into each vertebral body for 3-8ml.The recovery of vertebral body heights,bone cement filling and leakage were evaluated after X-ray examination.The pain relief rate was calculated by VAS method. Results After 3-24 months follow-up（average 13 months）,the pain relief rate of 48 cases was 86.2%.X-ray results showed that bone cement filling has satisfactory effects which the average height of vertebral body recovery rate was 60% to 80%.There was no height change of vertebral edge at the times of flexion and extension. Conclusion Multi-vertebral balloon kyphoplasty has good effect of minimally invasive and relieve pain,is an effective way to treat multiple vertebral body compression fracture in elderly patients.
