Panyun Mu, Peihua Qu, Jie Feng, Feng Xiong, Yimei Hu*,Yulin Li

Background: It is of great significance for clinical diagnosis, prevention and treatment of osteoporosis to deeply understand the pathogenesis and development process of osteoporosis through animal models of osteoporosis. This systematic review aims to summarize the modeling methods of osteoporosis, reveal the current situation and progress of animal models of osteoporosis, and compare the advantages and disadvantages of various modeling methods, so as to provide reference for clinical research.

Methods: CNKI, CBM database, VIP database, Wan fang database, PubMed database and EMBASE database were searched by computer from the database establishment to December 2020 with the key words of "animal model and osteoporosis" in Chinese and English respectively. The literatures were screened according to inclusion and exclusion criteria. The methods of osteoporosis modeling, the improvement of the methods and the advantages and disadvantages of each method are summarized.

Discussion: A total of 9303 related literatures were collected, and 112 eligible literatures were included. The establishment of an appropriate animal model is the key to the etiology, pathophysiology and drug therapy of osteoporosis. As the causes and pathophysiological changes of different types of OP have their own characteristics, the modeling methods are also different. Therefore, different modeling methods and experimental animals should be selected according to different experimental requirements.
