文题释义:
骨水泥固化过程:骨水泥从混合到完全固化,可分为湿砂期、拉丝期、面团期、固化期4个时相,完全固化所需要的时间受多方面的影响,比如室温、调制比例等。高黏度骨水泥在较短时间内可达到黏稠的状态,从混合开始到拉丝期末所需的时间比低黏度骨水泥较短。
骨质疏松压缩性椎体骨折的治疗:①保守治疗:当患者脊柱稳定性良好,系单个椎体或多个椎体单纯压缩性骨折,椎体压缩不超过 1/3,未伴发神经系统损伤,可采取保守治疗的方法;②外科治疗:长时间卧床可加重骨质疏松,造成骨折愈合延长,并易导致压疮、下肢深静脉血栓等并发症。椎弓根螺钉内固定是治疗压缩性骨折的传统手术方法,但老年脊柱骨折患者多合并骨质疏松,椎弓根螺钉对骨质疏松椎体的把持力不足,易产生切割现象,导致固定物松动,且术后常合并高度丢失严重,螺钉松动、脱出导致固定失败、假关节形成等并发症。近年来经皮椎体成形广泛应用于骨折、畸形不严重,无明显脊髓、神经受压症状的骨质疏松椎体压缩性骨折治疗。与卧床保守治疗及椎弓根螺钉内固定手术相比,经皮椎体成形具有见效快、创伤小、并发症少等优点,但需加压注入骨水泥,有较高的骨水泥渗漏率,且无支撑复位作用对压缩椎体高度恢复有限,不能矫正脊柱后凸畸形。
 
背景:传统骨水泥材料治疗骨质疏松压缩性椎体骨折时存在易发生散热效应、容易渗漏、力学强度与周围组织差异大等问题,严重影响骨质疏松压缩性椎体骨折的治疗效果。实验拟通过前瞻性自身前后对照开放试验来分析,一种新型高黏度骨水泥治疗骨质疏松压缩性椎体骨折的有效性。
方法/设计:在江苏大学附属宜兴医院进行前瞻性自身前后对照开放试验。对骨质疏松压缩性椎体骨折患者经皮椎体成形植入高黏度骨水泥,即刻结局指标为高黏度骨水泥植入前后改善患者疼痛症状的比较,以目测类比评分进行评价。中远期结局指标为患者脊柱功能的恢复情况以Oswestry功能障碍指数问卷表、椎体高度、骨水泥渗漏率、Barthel指数和SF-36生存质量量表评分评价。
讨论:试验将为高黏度骨水泥治疗骨质疏松压缩性椎体骨折提供临床应用依据。
伦理批准:试验方案已经江苏大学附属宜兴医院医学伦理委员会批准,批件文号:0136。试验获得患者及其家属的书面知情同意。

Abstract:

BACKGROUND: Traditional bone cement in the treatment of osteoporotic vertebral compression fracture easily induces heat dissipation effect, leakage, big difference in mechanical strength with the surrounding tissue, which greatly affects treatment effect of osteoporotic vertebral compression fracture. This prospective self-controlled open-label clinical trial is designed to analyze the effectiveness of a novel high viscosity bone cement for osteoporotic vertebral compression fractures.

METHODS/DESIGN: This prospective self-controlled open-label clinical trial will be performed in the Yixing Hospital Affiliated to Jiangsu University of China. High viscosity bone cement will be implanted in patients with osteoporotic vertebral compression fractures by percutaneous vertebroplasty. Immediate outcomes: Pain symptom of patients before and after implantation of high viscosity bone cement, and Visual Analogue Scale score. Middle- and long-term outcomes: The recovery of spinal function, Oswestry dysfunction index questionnaire, vertebral body height, bone cement leakage rate, Barthel index and SF-36 quality of life scale score.
DISCUSSION: This trial will provide a clinical basis for the treatment of osteoporotic vertebral compression fractures with high viscosity bone cement.
ETHICS APPROVAL: This trial has been approved by the Medical Ethics Committee, Yixing Hospital Affiliated to Jiangsu University (Approval number 0136). Patients and their family members have signed the informed consent.
