[Advances in researches on genetic predisposition to steroid-induced osteonecrosis of the femoral head]

Abstract

The pathogenesis of steroid-induced osteonecrosis of the femoral head (SONFH) is not very clear at present. For the past few years researches showed that the SONFH related to genetic predisposing factors. The related research progresses were reviewed in this article to show the correlation between genetic mutation and genetic polymorphism of steroid metabolism and transport, resistance and receptor, coagulation and fibrinolysis, lipid and bone metabolism and susceptibility to SONFH. The article also discussed current problems, countermeasure and future applications.
