Abstract: BACKGROUND: Osteonecrosis of the femoral head is a common and difficult disease in orthopedic department, with a high disability rate. At present, there is still no clear conclusion about its pathogenesis, as well as no ideal way to cure the disease. Therefore, it is necessary to use animal models to further study the etiology, pathogenesis and treatment of the disease.
OBJECTIVE: To review some common animal models of osteonecrosis of the femoral head in recent years, summarize and analyze the corresponding clinical symptoms and the advantages and disadvantages of each animal model, so as to provide the basis for the follow-up research in this area.
METHODS: The keywords of “femoral head necrosis” and “animal model” were used to search articles published between January 2000 to December 2019 in WanFang, VIP, CNKI, PubMed, Embase and Medline databases. Finally 42 eligible articles were included.
RESULTS AND CONCLUSION: The animal model of osteonecrosis of the femoral head has been used for many years, which really improves the understanding and research of this kind of orthopedic disease. However, at present, the related research of such diseases still needs to be further explored, through the establishment of more ideal and perfect animal models to achieve a new breakthrough in this research field.
