目的:探讨经皮椎体成形术(percutaneous vertebroplasty, PVP)治疗症状性许莫氏结节的可行性.方法:选取2004年5月至2015年9月符合纳入标准的65例有腰痛症状性许莫氏结节病人的资料进行回顾性研究分析.其中男性30例,女性35例,年龄为40~71岁,平均57.3岁.采用经皮椎体成形术治疗,术后进行围手术期指标观察,术前、术后1天,术后3个月、6个月及术后1年随访时采用视觉模拟量表评分(visual analogue scale, VAS)、采用Oswestry功能障碍指数、腰痛ODI评分标准(the oswestry disability index, ODI)进行评估临床疗效.结果:65例病人均顺利完成手术,无骨水泥渗漏等并发症,病人术中出血量2~5 ml,平均3 ml;平均手术时间30 min;平均住院时间3 d.所有病人术后均得到随访,随访时间18~36个月,平均24个月.与手术前相比较,所有病人术后1天、3月、6月及1年腰痛VAS评分和ODI较术前均得到明显改善,随着时间的延长,其症状逐渐好转,与术前比较有统计学差异(P < 0.05).结论:经皮椎体成形术是一种治疗症状性许莫氏结节有效的方法,具有创伤小,恢复快等优点.%Objective: To investigate the feasibility of percutaneous vertebroplasty treatment for back pain Schmorl nodes. Methods: From May, 2004 to September, 2015, 65 back pain originating Schmorl nodes, 30 male and 35 female patients with an average age of 57.3 years (40-71 years) were treated with percutaneous vertebroplasty. Results: The results of perioperative parameters and clinical outcomes were observed. The visual analogue scale (VAS) and Oswestry disablity index (ODI) was used to evaluate the pre-and post-operative(3,6,12 months) score which was used to evaluate clinical effects. The operations were completed successfully in all the 65 patients, and no bone cement leakage. Results: The operating time was 30 min on average (25-35) min; average operative blood loss was 3 ml (2-5) ml; average hospitalization time was 3 d (4-5) d. All patients were followed up for 24 months (18-36 months). The significant improvement could be found in back pain VAS and ODI scores between preoperative 1 day and postoperative follow-up at all time-point. Conclusion: The back pain originating Schmorl nodes could be treated with percutaneous vertebroplasty, and the advantage includes less invasion and quickly recovery.
