椎体后突成形术的骨水泥外漏

目的：探讨椎体后突成形术治疗骨质疏松性椎体骨折骨水泥外漏的原因和预防办法。方法：老年椎体骨质疏松性椎体骨折14例(18椎)，男6例，女8例；年龄64～81岁，平均74．5岁；下胸椎6例，腰椎8例。椎体骨折行球囊扩张椎体后突成形术后进行分析，根据X线片对骨水泥外漏进行分类，分析骨水泥外漏的可能原因、危险性以及预防对策。结果：14例随访1～8个月，平均6．2个月。14例中骨水泥外漏4例，分别漏向椎体的前、后、侧方及椎间隙，无不良后果发生。结论：骨水泥外漏是椎体后突成形术的主要并发症，只要病例选择合适、手术操作规范，骨水泥外漏是可以避免的。

Cement leakage of kyphoplasty for vertebral compressive fractures

Objective:To explore the causes and preventive ways of the bone cement leakages in kyphoplasty for osteoporosis compressive fractures.Methods:Fourteen patients with osteoporosis compressive fractures(18 vertebral bodies,thoracic 6,lumbar 8;male 6 cases,female 8 cases;ages ranged from 64 to 81 years,with an average of 74.5)were treated by saccule distension kyphoplasty.The surgical procedures and X-ray films were analyzed and the bone cement leakages were classified as the postoperative X-ray films.The causes,dangerousness and the prevention of the leakages of cement were analyzed.Results:All the patients were followed up for an anverage of 6.2 months(ranged from 1 to 8 months).Four patients of 18 were showed bone cement leakage,and the cement leaked out to the anterior,posterior,lateral,and intervertebral space of spines.There were no mal-outcomes.Conclusion:Bone cement leakages are the main complications in the kyphoplasty,as long as choosing the suitable cases,obeying specification of the surgical procedures,the leakages of cement might be avoided.
