摘要:

背景:研究证实经皮椎体成形治疗过程中,骨水泥固化后可明显提高骨折椎体的稳定性、强度及力学支撑等效能,但目前关于骨水泥骨折线内弥散状况对经皮椎体成形治疗影响的研究很少。
目的:分析胸腰椎体骨质疏松性压缩骨折骨折线内骨水泥弥散状况对经皮椎体成形治疗的影响。
方法:纳入胸腰椎体骨折疏松性压缩骨折患者90例,其中男42例,女48例,年龄53-80岁,均进行经皮椎体成形骨水泥注射治疗,根据骨水泥在椎体内的弥散情况分2组,研究组(n=60)骨水泥弥散良好,对照组(n=30)骨水泥弥散不佳。记录患者治疗前后的目测类比评分、Oswestry功能障碍指数、伤椎后凸角及与骨水泥材料相关的不良反应情况。
结果与结论:两组治疗前的目测类比评分、Oswestry功能障碍指数比较差异均无显著性意义;研究组治疗后3 d及末次随访的目测类比评分低于对照组(P < 0.05),治疗后3 d的Oswestry功能障碍指数、伤椎后凸角低于对照组(P < 0.05),两组末次随访的Oswestry功能障碍指数、伤椎后凸角及骨水泥渗漏情况比较差异无显著性意义。表明在经皮椎体成形治疗中,骨水泥弥散良好者疼痛缓解更明显,椎体稳定性更好,近期疗效更明显。

Abstract:

BACKGROUND: Bone cement solidification can improve the stability, strength and mechanical support of fractured vertebrae. However, there are few studies on the effect of bone cement dispersion within the fracture line on percutaneous vertebroplasty.
OBJECTIVE: To analyze the effect of bone cement dispersion within the fracture line of thoracolumbar osteoporotic vertebral compression fractures on percutaneous vertebroplasty.
METHODS: Totally 90 patients with thoracolumbar osteoporotic vertebral compression fractures were enrolled, 53-80 years old, including 42 males and 48 females. All these patients underwent percutaneous vertebroplasty with bone cement injection, and divided into two groups according to bone cement dispersion conditions: study group with good bone cement dispersion (n=60) and control group with poor bone cement dispersion (n=30). Visual analogue scale scores, Oswestry dysfunction index, Cobb’s angle and adverse reactions were recorded 
before and after treatment.
RESULTS AND CONCLUSION: There were no differences in the visual analogue scale score and Oswestry dysfunction index between the two groups before treatment (P > 0.05). The visual analogue scale scores were significantly lower in the study group than the control group at 3 days after treatment and at the last follow-up (P < 0.05); the Oswestry dysfunction index and Cobb’s angle were also lower in the study group than the control group at 3 days after treatment  (P < 0.05). However, no difference was found in the Oswestry dysfunction index, Cobb’s angle and bone cement leakage between the two groups at the last follow-up. These findings indicate that the percutaneous vertebroplasty show better effects on pain relief in patients with good bone cement dispersion that those with poor bone cement dispersion, and the vertebral stability is better as well as the short-term effect is more obvious.
