Abstract: BACKGROUND: The incidence of avascular necrosis of the femoral head is high, and it usually occurs in young and middle-aged people. Most of the patients with osteonecrosis have progressed to the middle and late stage when they come to see a doctor, and joint replacement may be the most effective treatment. However, the prosthesis has a certain service life, and if young patients undergo joint replacement, they may need to undergo one or more revision at a later stage. Early diagnosis, using simple methods to block the progression of osteonecrosis and avoiding the collapse of the femoral head are the goals of diagnosis and treatment of avascular necrosis of the femoral head. Therefore, it is of great practical significance to explore its pathogenesis and find new effective non-operative treatment.
OBJECTIVE: To explore the effect and pathogenesis of long-chain non-coding RNA on avascular necrosis of the femoral head, and to provide new ideas and methods for the treatment of avascular necrosis of the femoral head.
METHODS: The computer was used to search the relevant articles in PubMed database from 2011 to 2021. Abstract retrieval was used to search. Finally, articles were systematically summarized and analyzed. The role of long-chain non-coding RNA in regulating avascular necrosis of the femoral head and the new progress in the pathogenesis of avascular necrosis of the femoral head were systematically summarized and expounded. 
RESULTS AND CONCLUSION: A total of 47 articles were finally included. (1) There are many theories about the pathogenesis of avascular necrosis of the femoral head, all of which are more or less related to long-chain non-coding RNA. At present, the mainstream concept is related to bone marrow mesenchymal stem cells, brain microvascular endothelial cells apoptosis, abnormal differentiation, fat metabolism disorder, insufficient blood supply and gene polymorphism. (2) Regarding the role of long-chain non-coding RNA in the pathogenesis of avascular necrosis of the femoral head, there are still many problems to be solved. For example, the pathogenesis of avascular necrosis of the femoral head associated with long-chain non-coding RNA is still not very clear, the mechanism of long-chain non-coding RNA in bone microvascular endothelial cells of avascular necrosis of the femoral head on apoptosis and how the gene polymorphism in avascular necrosis of the femoral head regulates long-chain non-coding RNA. (3) Therefore, the study on the role of long-chain non-coding RNA in the pathogenesis of avascular necrosis of the femoral head is helpful to provide new ideas and methods for the clinical treatment of avascular necrosis of the femoral head.
