文题释义:
骨水泥:化学名称是聚甲基丙烯酸甲酯,也称丙烯酸骨水泥,是一种用于填充骨与植入物间隙或骨腔并具有自凝特性的生物材料,自从1958年Charney首次应用骨水泥固定股骨假体成功施行全髋关节置换以来,骨水泥己被广泛应用于骨科临床,骨水泥固定可保证术后假体的即时稳定,在骨组织-骨水泥-假体界面上无任何微动,允许术后早期负重,疗效肯定。骨水泥包括两部分灭菌包装,第一部分是聚甲基丙烯酸甲酯颗粒粉剂(直径10-150 µm),含有10%不透X射线的硫酸钡或氧化锆、1%二甲基甲苯胺引发剂和微量过氧化苯酰抑制剂;第二部分是甲基丙烯酸甲酯单体的液体,含有3%二甲基甲苯胺和减少单体自发聚合的微量过氧化苯酰。
椎体成形:临床全称为经皮穿刺椎体成形术,属于微创手术,是通过向病变椎体内注入骨水泥(聚丙烯酸甲酯)或人工骨达到强化椎体的技术。1984年由Deramond发明并首次应用,1987年法国医师Galibert首次应用于椎体血管瘤的治疗,1994年美国首次报道将椎体成形应用于骨质疏松椎体骨折的治疗。

 

背景:如何针对65岁以上老年人复发性骨质疏松椎体骨折进行有效治疗,成为临床治疗的重点和关注点。
目的:评价采用聚甲基丙烯酸甲酯骨水泥椎体成形修复老年复发性骨质疏松椎体骨折的临床疗效。
方法:选择24例老年复发性骨质疏松椎体骨折患者,按照患者自愿原则分别进行聚甲基丙烯酸甲酯骨水泥椎体成形治疗(微创组)和保守治疗(保守组),每组12例。对比治疗前后的腰背部目测类比评分、Oswesty功能障碍指数、伤椎前后缘高度比、脊柱后凸Cobb角及不良反应。

结果与结论:两组均完成12个月随访,微创组1例治疗时发生骨水泥渗漏,保守组1例治疗后1个月发生下肢深静脉血栓;微创组治疗后3 d、1个月、3个月、6个月、12个月的目测类比评分、Oswesty功能障碍指数、脊柱后凸Cobb角均低于保守组(P < 0.05),治疗后3 d、1个月、3个月、6个月、12个月的伤椎前后缘高度比均高于保守组(P < 0.05)。结果表明采用聚甲基丙烯酸甲酯骨水泥灌注修复老年复发性骨质疏松椎体骨折,近期可有效缓解疼痛,远期恢复了椎体高度和脊柱生理曲度,患者生活质量得到显著改善。

Abstract:

BACKGROUND: How to effectively treat recurrent osteoporotic vertebral compression fractures in the elderly over 65 years has become an issue of attention in the clinic.
OBJECTIVE: To evaluate the clinical efficacy of percutaneous vertebroplasty with polymethylmethacrylate bone cement for treating elderly recurrent osteoporotic vertebral compression fractures.
METHODS: Twenty-four patients with elderly osteoporotic vertebral compression fractures were divided into polymethylmethacrylate bone cement group (minimally invasive group) and conservative treatment group on a voluntary basis (n=12 per group). Visual analog scale score for low back pain, Oswesty dysfunction index, ratio of the anterior/posterior margin height of the injured vertebra, Cobb angle and adverse reactions were compared between the two groups before and after treatment.
RESULTS AND CONCLUSION: The 12-month follow-up was completed in all the patients. There was one case of bone cement breakage during treatment in the minimally invasive group and one case of lower limb deep venous thrombosis in the conservative treatment group at 1 month after treatment. Compared with the conservative treatment group, the visual analog scale score, Oswesty dysfunction index, and Cobb angle were significantly lower, but the ratio of the anterior/posterior margin height of the injured vertebra was significantly higher in the minimally invasive group at 3 days, 1, 3, 6 and 12 months after treatment (P < 0.05). These findings indicate that percutaneous vertebroplasty with polymethylmethacrylate bone cement for elderly recurrent osteoporotic vertebral fractures can strive for short-term pain relief and long-term recovery of the vertebral height and spinal Cobb angle, thereby significantly improving patient’s quality of life.
