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
