PKP治疗不伴神经损伤的骨质疏松性稳定型爆裂骨折

Effect of percutaneous balloon kyphoplasty in the treatment of vertebral osteoporotic stable burst fracture without neurologic injury

目的探讨经皮穿刺椎体后凸成形术（PKP）治疗不伴神经损伤的骨质疏松性稳定型爆裂骨折的初步临床效果。方法自2007-12-2011-06应用经皮穿刺球囊扩张椎体后凸成形术（PKP）治疗40例共40个椎体的不伴神经损伤的骨质疏松性稳定型爆裂骨折。随访观察患者的VAS疼痛评分以及影像学改变情况。结果本组随访12~24个月,平均19个月。术后患者疼痛均明显缓解,术后VAS评分、椎体前缘高度、椎体中部高度和伤椎后凸Cobb角改善显著。未出现骨水泥向椎管内渗漏。结论对于不伴神经损伤的骨质疏松性稳定型爆裂骨折,经皮穿刺球囊扩张椎体后凸成形术显著缓解疼痛、有效恢复骨折椎体的高度,是一种有效的治疗方法。

Objective To explore the efficacy and safety of percutaneous balloon kyphoplasty（PKP） in the treatment of vertebral osteoporotic stable burst fracture in patients without neurologic injury.Methods 40 patients（with a total of 40 painful stable burst fracture） who suffered from stable burst fracture and treated by PKP from December 2007 to June 2011,were enrolled in our study.The visual analogue scale（VAS）scores and radiographic results were recorded before the operation and after the operation,respectively.Results The patients were followed up for 12 to 24 months,average 19 months.All patients got significant pain relief.VAS score,the height of anterior column of the vertebrae and kyphotic angle were significantly improved after operation.No cement extravasation into vertebral canal occurred after kyphoplasty.Conclusion PKP is an effective method to treat vertebral osteoporotic stable burst fracture without neurologic injury.
