经皮椎体后凸成形术治疗老年Kummell病的临床疗效

Clinical effects of percutaneous kyphoplasty in the treatment of Kummell’s disease in elderly patients

目的探讨经皮椎体后凸成形术(PKP)治疗老年Kummell病的临床疗效。方法选择2011年1月至2017年12月于郑州人民医院行PKP的18例老年Kummell病患者为研究对象。于术前、术后2d及末次随访时采用疼痛视觉模拟量表(VAS)评分及Oswestry功能障碍指数(ODI)评估患者疼痛情况和生活质量改善情况。结果随访18~24个月,平均20.6个月;2例患者出现骨水泥渗漏,未见临床症状,无脊髓神经根损伤、肺栓塞等并发症发生。术后2dVAS评分和ODI与术前比较均下降(P<0.05),但与末次随访时比较差异未见统计学意义(P>0.05)。随访时未发现骨水泥松动、移位或再骨折情况。结论PKP是治疗Ⅰ期和Ⅱ期Kummell病的有效微创手术方法。

Objective To investigate the clinical effects of percutaneous kyphoplasty (PKP) in the treatment of Kummell’s disease in the elderly. Methods Eighteen elderly patients with Kummell’s disease, treated with PKP in the People’s Hospital of Zhengzhou from January 2011 to December 2017 were selected as research subjects. Pain visual analogue scale (VAS) and Oswestry dysfunction index (ODI) were used to evaluate the pain and quality of life (QOL) before operation, 2 days after operation and at the last follow-up. Results The patients were followed up for 18 to 24 months, with the average of 20.6 months. Two patients had bone cement leakage;no clinical symptoms or complications occurred, such as spinal cord nerve root injury, pulmonary embolism and so on. The VAS score and ODI were significantly decreased 2 days after operation (P<0.05), but there was no significant difference between these indexes in the last follow up and on 2 days after operation (P>0.05). No loosening of bone cement, displacement or re-fracture was found during follow-up. Conclusions PKP is an effective minimally invasive surgical method for the treatment of stage Ⅰ and Ⅱ Kummell’s disease.
