Abstract:
BACKGROUND:So far there is not an ideal animal model for clinical research of osteonecrosis of the femoral head, which hinders its development. OBJECTIVE:To compare the merits and characteristics of different methods and various animal models, and to provide a reference for selection of models of osteonecrosis of the femoral head. METHODS:Literature search was performed in databases of PubMed, EMBASE, Wanfang, and China National Knowledge Infrastructure, published from 2006 to 2014 by computers. The key words were“Osteonecrosis of the Femoral Head, Animal model, Vivo Experiment, Legg Calve Perthes disease, Osteoarthritis, Col apse of the Femoral Head, Trauma, Corticosteroid, Alcohol, Liquid Nitrogen”in English and Chinese, respectively. Final y, 48 articles were included. RESULTS AND CONCLUSION:Traumatic osteonecrosis of the femoral head models simulates the most common clinical type, which is more effective in Legg Calve Perthes disease. Glucocorticoid-induced osteonecrosis of the femoral head models is more suitable for etiology, pathology and comprehensive research. Physical osteonecrosis of the femoral head models could be used for evaluating treatment methods, such as surgery. The ideal animal models should be similar with human in anatomy, histology and biomechanics;pathology, pathophysiology, and radiographic progression of osteonecrosis of the femoral head can simulate the whole process of human osteonecrosis of the femoral head, and it is easy to be obtained, cost-effective and good repeatable.
