摘要
目的:探讨Sky骨扩张器系统在经皮椎体后凸成形术中应用的临床效果及手术操作要点.方法:对22例共29个椎体塌陷病变患者,应用Sky骨扩张器进行经皮穿刺、塌陷椎体扩张后注入骨水泥.随访观察患者疼痛视觉模拟评分(vasual analogue scale,VAS)及并发症情况.结果:29个椎体均单侧经椎弓根基底穿刺成功完成手术,手术时间每例35～85min,骨水泥注射量每个椎体5.3±1.2ml(3.0～7.6ml),分布均超过中线.骨水泥沿针道返流1个椎体,少量椎管内漏1个椎体,但均无临床症状;无其它并发症.所有患者疼痛缓解,VAS术前为9.2±1.8分,术后第3天为3.1±2.8分;随访1～3个月(平均2个月),随访时VAS为2.9±3.3分.5个椎体高度显著恢复.结论:Skv骨扩张器是经皮脊柱后凸成形术的新型器械,具有可控定向扩张特点,初步观察,安全有效.
Objective:To evaluate the clinical efficacy and operating technique of Sky bone expander system in percutaneous kyphoplasty.Method:22 cases(29 vertebrae),including 20 cases(25 vertebrae) of osteoporotic vertebral body compression fracture,1 case(2 thoracical vertebrae) of metastasis tumor and 1 case(2 vertebrae) of multiple myeloma,underwent percutaneous kyphoplasty with Sky bone expander system either in prone position or lateral recumbent position.The average time of follow-up was 2 months(ranging from 1 to 3 months).Result:All cases were successfully experienced the procedure using unipedicle technique.Operation time for each case was from 35 minutes to 85 minutes.The mean volume of PMMA and Ca/P bone cement injected into each vertebra body was 5.3±1.2ml(range from 3.0 to 7.6ml).Extravertebral leakage of bone cement were observed in two vertebrae body with no symptome.The height of compressed vertebra body recovered obviously in five.The vasual analogue scale(VAS) was 9.2±1.8 before operation,3.1±2.8 at day 3 postoperatively and 2.9±3.3 at follow-up.Conclusion:Sky bone expander system is a new instrument for minimally invasive spinal surgery.The orientation could be easily controlled during the procedure.The percutaneous kyphoplasty with Sky bone expander system is effective and secure in treating osteoporotic vertebral body compression fractures,spinal metastasis tumor and multiple myeloma.
