摘要:

文题释义:
聚甲基丙烯酸甲酯:是一种无机高分子骨修复材料,由聚甲基丙烯酸甲酯和单体丙烯酸甲酯聚合而成,属传统的骨替代材料,其聚合过程大致分为稀薄、黏稠、硬化、产热4个时期。
弯角椎体成形:是传统椎体成形的改良,通过弧形穿刺针经单侧椎弓根穿刺获得骨水泥在伤椎双侧分布,以达到迅速缓解患者疼痛、均衡增加椎体强度和稳定性的骨质疏松性椎体压缩骨折微创治疗方法。

背景:弯角椎体成形是治疗骨质疏松性椎体压缩骨折的新方法,具有较好的临床疗效,但治疗中的骨水泥分布情况缺乏深入研究。
目的:回顾性分析弯角椎体成形治疗骨质疏松性椎体压缩骨折的临床效果与骨水泥分布特点。
方法:选择2017年6月至2018年2月青岛市市立医院收治的28例胸腰椎单椎体新发骨质疏松性椎体压缩骨折患者,其中男2例,女26例,年龄62-86岁,均接受弯角椎体成形骨水泥注射治疗,于穿刺对侧、椎体中部和穿刺侧3处分别推注骨水泥。术前、术后48 h、术后6个月,拍摄X射线片观察骨水泥渗漏与伤椎前缘高度变化,通过CT扫描观察椎体内的骨水泥分布,利用目测类比评分与Oswestry功能障碍指数评估患者功能改善情况。试验方案已获得青岛市市立医院伦理审批。
结果与结论:①28例患者中6例发生骨水泥渗漏,其中椎旁渗漏4例,椎间隙渗漏2例,均无临床症状;CT扫描显示,骨水泥主要分布于椎体中前2/3,最大分布层面骨水泥面积为(4.5±0.9) cm2,穿刺对侧骨水泥面积为(2.0±0.5) cm2,穿刺侧骨水泥面积为(2.5±0.7) cm2,骨水泥分布面积穿刺对侧/穿刺侧为0.85±0.27;②28例患者术后伤椎前缘高度与术前比较差异无显著性意义(P > 0.05);③术后48 h、6个月,28例患者的目测类比评分与Oswestry功能障碍指数评分均较术前明显改善(P < 0.05);④结果表明,弯角椎体成形治疗骨质疏松性椎体压缩骨折临床疗效确切,骨水泥分布较均匀。

Abstract: BACKGROUND: Percutaneous curved vertebroplasty is a new method for the treatment of osteoporotic vertebral compression fractures, which can achieve a good therapeutic effect, while the distribution of bone cement has not been explored thoroughly.
OBJECTIVE: To retrospectively analyze the therapeutic effect of percutaneous curved vertebroplasty and the distribution characteristics of bone cement in the treatment of osteoporotic vertebral compression fractures.
METHODS: A total of 28 patients with osteoporotic vertebral compression fractures of a single thoracic or lumbar vertebrate, who were admitted to Qingdao Municipal Hospital from June 2017 to February 2018, including 2 males and 26 females, aged 62-86 years old, underwent percutaneous curved vertebroplasty and were retrospectively reviewed. The bone cement was injected at the puncture side, the middle of the vertebrate and the contralateral side respectively. The change of anterior vertebral body height of the injured vertebrae and the leakage of bone cement postoperatively were observed according to X-ray images preoperatively, 48 hours and 6 months postoperatively. The bone cement distribution within the vertebrate was observed by CT scanning. Visual analogue scale score and Oswestry disability index were recorded for the evaluation of recovery. All protocols were approved by the Ethical Committee of Qingdao Municipal Hospital.
RESULTS AND CONCLUSION: (1) There were 6 out of 28 cases of bone cement leakage, including 4 cases of paravertebral leakage and 2 cases of intervertebral space leakage, and no clinical symptoms were observed in all the 6 cases. CT scanning showed that the bone cement was mainly distributed in the anterior 2/3 of the vertebral body. The maximum distribution area of bone cement was (4.5±0.9) cm2, with the contralateral area (2.0±0.5) cm2 and the puncture side area (2.5±0.7) cm2, which makes the ratio of the puncture side area versus contralateral area 0.85±0.27. (2) The anterior vertebral body heights preoperatively showed no significant difference than those postoperatively in 28 patients (P > 0.05). (3) The visual analogue scale score and Oswestry disability index 48 hours and 6 months postoperatively were both significantly different from those before operation (P < 0.05). (4) The results showed that percutaneous curved vertebroplasty treatment of osteoporotic vertebral compression fractures has the advantages of accurate surgical effects and even distribution of bone cement.
