CT引导下单球囊扩张椎体后凸成形术的临床应用

The Clinical Application of Single Baloon cross Mediline Expansion in Kyphoplasty Under CT Guidence

目的探讨CT引导下经椎弓根单球囊跨中线扩张后凸成形术治疗骨质疏松性脊柱压缩骨折的疗效及优缺点。资料与方法 37例疼痛性骨质疏松脊柱压缩性骨折患者,累及椎体47个。在CT引导下,经一侧椎弓根单球囊置入椎体中线区,使单球囊在椎体内跨中线扩张,骨水泥在椎体内跨中线分布,术后观察患者的疗效及骨折复位情况。结果 37例(47个椎体)均穿刺成功,术前受累椎体前缘高度(12.05±3.73)mm,术后恢复至(16.49±4.85)mm,差异有统计学意义,后凸畸形由术前(23.4±5.4)°,矫正至术后(12.3±4.7)°,手术前后差异有统计学意义。结论 CT引导下单球囊椎体后凸成形术,路径设计合理,穿刺成功率高,避免多次重复穿刺,所以创伤小、手术时间短;有效地解除了由于骨质疏松性脊柱压缩骨折引起的多种临床症状。

Objective To evaluate the clinical application of percutaneous kyphoplasty（PKP） guided by CT for the treatment of vetebral body osteoporotic compression fracture with single ballon cross midline expansion.Materials and Methods 37 cases of vertebral compression fracture had been diagnosed and PKP operation was adopted for the treatment of the 47 vertebral affected.Under CT guidence,Kyphoplasty was performed using a unilateral,single balloon through unilateral transpedicular.A final ballon position was in the midiline of the vertebral body with the balloon cross midline expansions and bone cement filled.The therapeutic effected as well as dislocation of fracture were observed.Results CT guidence PKP operations were all successfully performed.Vertebral heights and Cobb angle were improved significantly after the surgery.Conclusion CT guided PKP using single ballon is a safe technique with minial invasive as well as less operation time,and effectively relieve clincial symptoms caused by vertebral compression fracture.
