Abstract: BACKGROUND: Osteonecrosis of the femoral head is a common disabling disease in orthopedics. The development of the disease is difficult to be reversed, and improper treatment methods can easily lead to the collapse of the femoral head, leading to the partial or complete loss of hip function, which seriously affects the life of patients.
OBJECTIVE: To summarize the methods of collapse assessment and prediction, and to propose that the combination of them can provide more accurate evidence for the selection of treatment.
METHODS: PubMed was searched with the key words of “staging and classification, ONFH, collapse prediction, assessment”. CNKI and Wanfang database were retrieved using the key words of “staging classification, femoral head necrosis, collapse prediction”. The search time was from January 1991 to January 2020. Articles unrelated with the research and repetitive one were excluded, and finally 62 articles met the criteria for review. 
RESULTS AND CONCLUSION: (1) The classification and staging of osteonecrosis of the femoral head can effectively evaluate the existence and degree of collapse, but still have their limitation on prediction of collapse occurrence. (2) The combined application of collapse prediction method can improve the accuracy of the evaluation. The specific combination effect still needs further studies.
