Abstract:

BACKGROUND: Incidence of cervical radiculopathy is highest in cervical spondylosis. The ideal animal model is the prerequisite for studies on cervical radiculopathy. However, there are many problems in the conversion of clinical diseases into animal models, which limits the research on the pathogenesis and treatment of cervical radiculopathy.

OBJECTIVE: To review the selection and construction methods of the cervical radiculopathy model, so as to improve an ideal animal model of cervical radiculopathy.
METHODS: A retrieval of Medline, PubMed, CNKI, WanFang and VIP databases was performed for the articles addressing experiments and basic studies of constructing cervical radiculopathy published before December 2017. The keywords were “cervical radiculopathy, cervical spondylotic radiculopathy, cervical nerve root compression, animal, model” in English and Chinese, respectively. Finally 41 eligible articles were included for result analysis.
RESULTS AND CONCLUSION: (1) There are many kinds of animals used for constructing cervical radiculopathy models, and the modeling methods are various, which are divided into two categories: direct and indirect stimulation to cervical nerve roots. (2) The direct stimulation to cervical nerve root model is divided into instantaneous physical compression, transient mechanical stimulation combined with chemical stimulation, continuous physical compression, and transient mechanical stimulation combined with chemical stimulation. It is characterized by reliability, strong controllability, short cycle, but a certain difficulty in operation. (3) The indirect stimulation to cervical nerve root model is divided into surgical intervention and non-surgical intervention. Its characteristics are consistent with the pathological process of chronic degeneration of human body, simple operation, but long modeling period, poor reliability and repeatability. (4) In the basic research of cervical radiculopathy, appropriate animal models should be selected according to research requirements and purposes, experimental conditions and funds. It will be a goal to further create and study more perfect cervical radiculopathy animal models from economy, flexibility, reliability and controllability.
