Abstract:

Osteonecrosis of the femoral head (ONFH) is a very destructive and disabling common orthopedic disease, and its pathogenesis has not been fully determined. Exosomes are vesicle-like carriers with bilayer membrane structure, which contain contents such as abundant proteins and nucleic acids, and are one of the key modes of cell communication. In recent years, a large number of experimental conclusions have confirmed that exosomes play a key role in pathophysiological activities such as circulatory disturbance, fat metabolism disorders, altered osteogenic ability, and apoptosis in patients with ONFH, as well as prevention and treatment. This article reviews the pathogenesis of exosomes and its potential application in the treatment of ONFH, proposes that exosomes can be used as an important treatment for ONFH.

Key words: Femur head necrosis, Thrombosis, Lipid metabolism disorders, Bone regeneration, Apoptosis, Exosomes
