经皮椎体后凸成形术治疗骨质疏松性椎体压缩骨折

Treatment of Spinal Compressive Fracture Patients with Osteoporosis by Means of Percutaneous Kyphoplasty

目的评价经皮椎体后凸成形术治疗骨质疏松性椎体压缩骨折的临床效果。方法对50例(56椎)骨质疏松性椎体压缩骨折的患者应用球囊式椎体扩张器对病椎进行扩张,并用骨水泥进行填充,采用视觉模拟量表(visualanalogue scales,VAS)及Stauffer-Coventry评定术后疗效。结果本组病例手术均获得成功,椎管内硬膜外渗漏2例,椎间盘渗漏3例,椎弓根穿刺针道渗漏1例,均未引起严重的神经症状及肺栓塞等致命并发症。VAS由术前(7.3±0.6)分降到术后(2.9±0.3)分,随访6个月时(1.9±0.4)分,差异有统计学意义(P<0.05)。临床效果SC评分,优29例,良16例,可5例,优良率90%。结论经皮椎体后凸成形术手术创伤小、时间短,可迅速有效地缓解疼痛,远期疗效可靠,具有很好的临床应用价值。

Objective To analyze the clinical effect of percutaneous kyphoplasty（PKP）in the treatment of osteoporotic vertebral compression fracture.Methods 50 patients（56 vertebrae） of osteoporotic vertebral compression fracture had applied vertebral body balloon-type expander for expansion of the diseased vertebrae,and bone cement filling,through the pain visual analogue score（VAS）and Stauffer-Coventry（SC）compared before and after surgery. Results The patients were successful surgery,2 case of patients with spinal epidural leakage,3 cases of patients with disc leakage,1 case of patients with pedicle needle channnel,but all have no neurological symptoms.Clinical effects of SC score：excellent in 29 cases,good in 16 cases,good rate was 90%.Conclusion The PKP technique has the advantages of less invasive incision,and short operation time.It can be quickly and effectively relieve pain,long-term efficacy was reliable,with commendable clinic applicative value.
