经皮椎体后凸成形术治疗胸腰椎骨质疏松性压缩骨折疗效观察

Clinical efficacy of percutaneous kyphoplasty in the treatment of osteoporotic vertebral compression fractures

目的经皮椎体后凸成形术治疗胸腰椎骨质疏松性压缩骨折疗效观察。方法选取我院2014年1月~2016年1月共40例胸腰椎骨质疏松性压缩骨折患者,随机分为甲乙两组各20例。其中甲组将骨水泥通过疼痛侧椎弓根准确灌注在MR提示的水肿区,不超过中线;乙组则通过疼痛侧椎弓根将骨水泥准确灌注在病椎中间,骨水泥以中线为主,并弥散在椎体的双侧,则为手术成功。结果甲组患者VAS评分、ODI指数与乙组患者相比无统计学差异(P>0.05);乙组患者Cobb’s角、SI指数低于甲组,差异有统计学意义(P<0.05)。结论从比较疼痛侧的椎弓根进入,准确将骨水泥灌注在椎体中间的MR提示椎体上或下的水肿影区域,患者病椎强度恢复较为均衡,且骨水泥发热灭活椎体内的神经较为完全,故疼痛缓解较明显,可明显提高手术治疗效果。

Objective To observe the clinical efficacy of percutaneous kyphoplasty for osteoporotic vertebral compression fractures. Methods A total of 40 patients with osteoporosis fracture fracture from Jan 2014 to Jan 2016 were selected and randomly divided into group A and group B, each of 20 cases. Group A underwent bone cement accurate perfusion in the edematous region of MR presentation through the painful lateral pedicle; Group B underwent bone cement accurate perfusion in the middle of the affected vertebra through the painful lateral pedicle, and diffused bilaterally in the vertebral body, and the operation was successful. Results The VAS score and ODI index were not statistically significant between two groups （P 〉 0.05）. The Cobb＇s angles and SI index of group B were lower than those of the group A, and the difference was statistically significant （P 〈 0.05）. Conclusion Strength recovery of affected vertebra in patients with bone cement accurate perfusion in the edematous region of MR presentation through the painful lateral pedicle is equilibrium, and inactivation of vertebral nerve by bone cement generating heat is more complete, so the pain relief is more obvious, and clinical efficacy is improved.
