文题释义:
腰椎棘突间撑开器:总体的设计理念是利用该装置撑开责任节段的棘突间隙并限制相应节段的后伸运动,防止腰椎过伸时神经压迫症状加重,增加责任节段椎管及椎间孔面积,降低椎间盘及小关节突压力,减小腰椎生理前凸增加腰椎后凸,一定程度上能减少黄韧带受压折叠的程度,进而缓解黄韧带对椎管的压迫,从而缓解腰椎退行性疾病神经受压的症状。
腰椎棘突间撑开器三维有限元分析:运用计算机三维模型,从结构、形态、弹性模量上模拟人体腰椎屈伸、侧弯、轴向旋转活动,通过应力云图直观显示在不同位置棘突间撑开器、椎体置入节段及临近节段的应力分布及腰椎活动度等情况。有限元分析只是一种模拟实验,因此其对该装置的评价需要结合动物实验和临床观察,才能更接近实际。
 
摘要
背景:腰椎退行性疾病是骨科常见疾病之一,治疗方法有保守治疗、椎体间融合术、椎体间非融合术,其经典手术治疗方法是后路腰椎体间融合术。非融合技术临床应用日益广泛,棘突间撑开器是其中一个重要代表,与传统融合技术相比具有独特的生物力学优势和较理想的临床疗效,但潜在的问题与不足随着应用的增多也逐渐显现。
目的:对腰椎棘突间撑开器的生物力学特点及弊端,临床适用性的价值与争议,以及临床适用性受限原因和生物力学方面的改进理念进行综述,为广大临床医生及进一步的研究提供参考。
方法:第一作者以“腰椎,棘突间撑开器,棘突间撑开装置,生物力学,临床治疗效果,成本效益,腰椎棘突间撑开器并发症,棘突间撑开器适应证和禁忌证,棘突形态,新型棘突间撑开器”为关键词在中国知网、万方数据库进行检索,在PubMed数据库、SpringerLink数据库以“Lumbar spine,interspinous spacer,interspinous devices,biomechanics,clinical therapeutic effect,cost-effectiveness,complications of interspinous spacer,indication and contraindication of interspinous spacer,spinous process morphology,new interspinous spacer”进行检索。采纳2003至2018年的相关研究,排除重复研究。通过阅读摘要初步筛选,共选取42篇文献进行综述,其中中文文献4篇,英文文献38篇。
结果与结论:①腰椎棘突间撑开器具有独特生物力学特点,与此同时,棘突间撑开器自身结构设计上也存在一些弊端;②各种腰椎棘突间撑开装置在短、中期随访中均具有良好的临床疗效,但仍存在复发率及二次翻修手术率高、临床疗效不确切、成本效益低、并发症频出等问题;③手术适应证和禁忌证掌握不准确,术中操作不规范,棘突解剖形态存在特异性是临床适用性受限的主要原因;④一些新型棘突间撑开器的研发为棘突间撑开器生物力学研究提供了改进理念与方向。

Abstract:

BACKGROUND: Lumbar degenerative disease is a common disease in orthopedics. The treatment methods include conservative treatment, interbody fusion and interbody non-fusion, and the classical surgical treatment is posterior lumbar interbody fusion. Non-fusion technology has become more and more widely used, especially the interspinous spacer. Compared with the traditional fusion technology, it has unique biomechanical advantages and ideal clinical efficacy, but the potential problems and deficiencies are gradually emerging.

OBJECTIVE: To review the biomechanical characteristics and disadvantages of interspinous spacer, the value and controversy of clinical applicability, the reasons for the limitation of clinical applicability and the improvement in biomechanics, so as to provide a reference for clinical practice.
METHODS: The first author retrieved CNKI, WanFang, PubMed and SpringerLink databases with the keywords of “lumbar spine, interspinous spacer, interspinous devices, biomechanics, clinical therapeutic effect, cost-effectiveness, complications of interspinous spacer, indication and contraindication of interspinous spacer, spinous process morphology, new interspinous spacer” in English and Chinese, respectively. Relevant studies published between 2003 and 2018 were included and the repeated studies were excluded. Finally, 42 studies were enrolled, with 38 English studies and 4 Chinese studies through reading abstracts.
RESULTS AND CONCLUSION: (1) The interspinous spacer holds special biomechanical characteristics and certain shortcomings in structure. (2) All kinds of interspinous spacers obtain good clinical effects in short- and medium-time follow-up. However, there are some disadvantages, such as high rate of recurrence and reversion, inaccurate clinical efficacy, low cost-effectiveness, and frequent complications. (3) The inaccurate surgical indications and contraindications, unstandardized operation and the specificity in the anatomic morphology of spinous process are the main reasons for the limitation of clinical applicability. (4) The research and development of new device provide an improved concept and direction for biomechanical study.
