摘　　要：目的:观察并分析Sky骨扩张系统在椎体后凸成形术中的临床效果,为临床应用提供一定的依据。方法:收集我科应用Sky骨扩张系统进行椎体后凸成形术的9例患者,记录术前及术后腰背部疼痛程度的视觉模糊评分(VAS评分)和各病椎椎体前缘、中线、后缘高度,术后平均随访3个月,结果用配对t检验进行统计学分析。结果:所有患者都顺利康复出院,平均住院时间5 d;1个椎体出现骨水泥向椎体前缘渗漏,但未引起临床症状,未发现向椎管渗漏。术前患者的VAS评分平均为8.2分,术后第1天平均降至2.9分,出院时评分为2.5分,术后3个月随访平均评分为2.1分,手术前后差异有统计学意义(P<0.01)。有7个椎体高度有显著性恢复。结论:Sky骨扩张系统作为新的经皮椎体成形术器械,具有良好的临床效果和安全性。Objective： To measure and analyze the clinical efficacy of Sky bone expander system on percutaneous kyphoplasty. Methods： Nine cases（10 vertebrae） , which had undergone percutaneous kyphoplasty with Sky bone expander system, were collected, including seven cases （eight vertebrae） of vertebral compression fracture（VCF） and two cases（two vertebrae） of metastasis tumor. The patients were evaluated with Visual Analogue Pain Scale（VAS）. The anterior height, midline height, and posterior height of vertebrae were measured preoperatively and postoperatively. The average time of follow-up was three months. All data were used paired-samples T test. Results： All patients were successfully finished the operation. The average time of in hospital was five days. One case was found PMMP leak out without any symptom. No leakage were found in vertebral canal. The average VAS score was 8.2 before operation, 2.9 in one day after operation, 2.5 when leave the hospital and 2.1 after three months post-operation （P〈0.01）. The height of compressed vertebra body recovered obviously in eighteen. Conclusion： Sky bone expander system, as a new instrument on percutaneous kyphoplasty, is effective and safe in treating osteoporotic vertebral body compression fracture and spinal metastasis.
