文题释义:
骨水泥块类型
:按照灌注的骨水泥在椎体内固化后形成的形态,分为骨小梁型、团块型和混合型。骨水泥块的形态决定了骨水泥块与椎体内骨组织接触的表面积,表面积越大,骨水泥与骨组织结合度越高,骨水泥-骨界面的抗压缩和抗扭转能力越强。
伤椎再骨折:伤椎灌注骨水泥一段时间后,椎体出现高度下降、椎体内裂隙征、骨水泥块形态位置改变、椎体内微骨折现象。伤椎术后发生再骨折的因素很多,普遍认为骨质疏松疾病本身、骨水泥灌注后局部生物力学改变以及骨水泥椎间盘渗漏是高危因素。抗骨质疏松治疗仍然是预防椎体成形术后再发骨折的基础,骨水泥材料研究的进展与骨水泥在椎体内均匀弥散,也会降低椎体成形术后再骨折的风险。


背景:骨水泥灌注治疗骨质疏松性椎体压缩骨折后,随着骨质疏松的进行和骨水泥与骨组织间隙的增大,骨水泥-骨界面的抗压缩和抗扭转能力下降,骨水泥块在椎体内的微运动幅度增加,易导致伤椎再骨折发生。
目的:探讨3种方式灌注骨水泥治疗骨质疏松性椎体压缩骨折的临床疗效。
方法:以单椎体骨质疏松性压缩骨折患者为研究对象,进行椎体成形术、椎体后凸成形术及椎体成形术分次灌注骨水泥治疗各60例,整理相关数据,分析椎体内骨水泥块的类别与治疗方式的关系,了解患者长期疼痛缓解及日常活动功能改善、椎体高度及骨水泥块形态位置改变、伤椎再骨折发生等情况。
结果与结论:①3组治疗后的目测类比评分、Oswestry功能障碍指数和Cobb's角均较治疗前改善(P < 0.05);治疗后6个月与末次随访相比差异无显著性意义,各时间点组间相比差异无显著性意义,说明3种方法缓解疼痛和恢复行动的效果无差异,均能够防止椎体高度丢失,维护脊柱的力学性能;②骨水泥形态位置发生改变及伤椎再骨折均出现在团块型骨水泥病例中,为增加长期疗效,在灌注骨水泥时应尽可能在椎体内形成混合型或骨小梁型骨水泥。

Abstract:

BACKGROUND: After the treatment of osteoporotic vertebral compression fractures with bone cement implantation, deteriorative osteoporosis and the distance augment between bone cement and bones result in a decrease in bone cement-bone interface compression strength and torsion strength, and then the bone cement tends to displace, which is easy to cause a secondary vertebral fracture.
OBJECTIVE: To investigate the clinical efficacy of bone cement implantation via three approaches on osteoporotic vertebral compression fractures.
METHODS: Sixty patients with single osteoporotic vertebral compression fracture were treated with vertebroplasty, percutaneous kyphoplasty or fraction cement vertebroplasty. All data were collected to analyze the correlation between the bone cement morphology and treatment method, and to detect the visual analogue scale, Oswestry disability index, Cobb angle and incidence of secondary vertebral fractures.
RESULTS AND CONCLUSION: The visual analogue scale scores, Oswestry disability index, and Cobb angle in the three groups were significantly improved after treatment (P < 0.05). All above indicators showed no significant difference among groups at each time point after treatment, suggesting that these three kinds of treatments exert the same effects on pain relief, functional recovery, preventing the vertebral height loss and maintaining spinal mechanical properties. Bone cement displacement and secondary vertebral fracture occurred after clotted cement implantation. Therefore, mixed and trabecular-shaped grafts are preferred, aiming to achieve good long-term treatment outcomes in osteoporotic vertebral compression fractures.
