Abstract:

BACKGROUND: Cervical spondylotic myelopathy is one of the most serious types of cervical spondylosis. The histopathological study of cervical spondylotic myelopathy is not very clear, mainly because of the lack of ideal animal models.

OBJECTIVE: To review the common methods of making cervical spondylotic myelopathy model, and analyze and evaluate the different methods of making the model, so as to promote the improvement and perfection of cervical spondylotic myelopathy animal models in the future. 

METHODS: The “cervical spondylotic myelopathy, cervical spinal compression, animal model” in Chinese and English, respectively were used as keywords. The first author retrieved the literature concerning construction methods of cervical spondylotic myelopathy animal model in CNKI, Wanfang, VIP, PubMed, Medline and Embase databases from 2000 to 2019, and all data were filtered for analysis and evaluation.    

RESULTS AND CONCLUSION: (1) There are many construction methods of cervical spondylotic myelopathy animal model at present, which can be divided into two types: dynamic modeling methods and static modeling methods, and their advantages and disadvantages coexist. (2) Screw compression is the most common construction method of cervical spondylotic myelopathy animal models, which has the advantages of strong controllability and short modeling cycle, but the damage to cervical spinal cord of animals is more serious and has a high fatality rate. The technology of expansion material compression method is difficult, but it has a high success rate and high reliability. It needs to be further improved and promoted. (3) At present, the construction methods of cervical spondylotic myelopathy animal model still have many disadvantages, and need to be improved on the basis of previous modeling by researchers, so as to realize good reproducibility, repeatable and scalable animal model making and provide a better clinical theoretical basis for cervical spondylotic myelopathy in the future.

Key words: cervical spondylotic myelopathy, cervical spinal cord compression, experimental animal, animal model, modeling, screw in screws, expansion material, research progress, evaluation
