文题释义:
腰椎有限元模型:腰椎有限元模型的建立是利用 CT、MRI等方法获取腰椎的影像学资料,通过MIMICS、GEOMAGIC以及SOLIDWORK等相关的软件对图像进行处理并建立有限元模型。随着技术的发展,腰椎有限元模型的建立在一定程度上完善了腰椎间盘、连接韧带、椎体间小关节、关节囊等软组织以及肌肉等结构的模型建立。
腰椎退行性疾患:随着国内人口老龄化的加剧,腰椎退行性疾病日益增多,常见病症如腰椎间盘突出症、腰椎管狭窄症、腰椎滑脱症等疾病,这类疾患常由于椎间盘退变导致神经根受到压迫或刺激产生明显的腰痛合并下肢麻木、疼痛,往往影响患者的生活质量,严重时会导致行走困难。

 
摘要
背景:腰椎退行性疾患由于保守治疗不能从根本上解决压迫或畸形等病因,许多患者在保守治疗无效或合并神经根病损的情况下选择手术治疗,而腰椎退行性疾患及其诊疗过程的生物力学特征是临床医师尤为关注的。与传统的生物力学实验方法相比,有限元技术具有可信度高,实验成本低,可重复性好等优点。
目的:通过有限元技术对腰椎退行性疾患及融合术后腰椎的应力及稳定性进行研究,全面分析有限元技术在腰椎退行性疾患中的应用。
方法:由第一作者检索至 2018 年 10月为止 PubMed 数据(http://www.ncbi.nlm.nih.gov/PubMed)及 CNKI中国期刊全文数据库(http://www.cnki.net/),以“lumbar vertebra,finite element method,biomechanics”为英文检索词,“腰椎,有限元法,生物力学”为中文检索词,检索摘要内同时包含上述检索词的文献,并排除重复性研究。符合纳入标准的43篇文献中,中文18篇,英文25篇。
结果与结论:①利用有限元技术对腰椎退行性疾患的诊疗过程进行研究具有重要意义,并为临床医师提供了生物力学依据;②随着科学技术的飞速发展及腰椎退行性疾患有限元模型的逐渐完善,利用有限元技术为患者制定个性化的治疗成为可能;③相信随着计算机技术的发展,有限元技术将会更加完善,为临床医师提供更多帮助。

Abstract:

BACKGROUND: Because conservative treatment of lumbar degenerative diseases cannot fundamentally solve the causes of compression or deformity, many patients choose surgical treatment when conservative treatment is ineffective or combined with nerve root lesions. The biomechanical characteristics of lumbar degenerative diseases and their diagnosis and treatment are of particular concerns to clinicians. Compared with the traditional biomechanical experimental methods, the finite element method has the advantages of high reliability, low cost and good repeatability.

OBJECTIVE: To study the stress and stability of lumbar degenerative diseases and lumbar spine after fusion by finite element method, and to analyze the application of finite element method in lumbar degenerative diseases.
METHODS: PubMed data (http://www.ncbi.nlm.nih.gov/PubMed) and CNKI (http://www.cnki.net/) were retrieved by the first author until October 2018. The keywords were “lumbar vertebra, finite element method, biomechanics” in English and Chinese, respectively. Repetitive studies were excluded, and 43 articles eligible for inclusion criteria were included, including 18 Chinese and 25 English articles.
RESULTS AND CONCLUSION: (1) It is of great significance to study the diagnosis and treatment process of lumbar degenerative diseases using finite element method, and it provides biomechanical basis for clinicians. (2) With the rapid development of science and technology and the gradual improvement of finite element model, it is possible to use finite element technology to develop personalized treatment for patients. (3) It is believed that with the development of computer technology, the finite element technology will be more perfect and provide more help for clinicians.

Key words: finite element analysis, lumbar degenerative diseases, lumbar fusion, stress, biomechanics
