Abstract

Steroid-induced necrosis of the femoral head SONFH is a major subtype of non-traumatic osteonecrosis and is often associated with long-term or high-dose glucocorticoid therapy in patients with systemic lupus erythematosus rheumatoid arthritis nephrotic syndrome and other conditions. SONFH has an insidious onset and may rapidly progress to femoral head collapse ultimately requiring total hip arthroplasty and markedly impairing quality of life in young and middle-aged adults. Recent evidence indicates that SONFH is driven by a complex pathogenic network rather than a single mechanism. Key processes include imbalance of adipogenic versus osteogenic differentiation in bone marrow mesenchymal stem cells injury and dysfunction of bone microvascular endothelial cells with thrombosis immune-inflammatory dysregulation multiple forms of regulated cell death apoptosis dysregulated autophagyferroptosis pyroptosis and necroptosis), oxidative stress and epigenetic regulation. Glucocorticoids can promote lipid metabolic disorders and increased intraosseous pressure resulting in local hypoperfusion meanwhile reactive oxygen species accumulation suppression of the Nrf2 antioxidant pathway and disruption of signaling such as PI3K/AKT/eNOS aggravate cellular injury and amplify inflammatory responses leading to uncoupled bone remodeling. Multi-omics and bioinformatics studies further suggest that biomarkers and targets including miR-486-5p FAR591 the SLC7A11/GPX4 axis and NLRP3 may facilitate early diagnosis and therapeutic intervention. This review summarizes recent advances in the pathogenesis of SONFH highlights crosstalk among key pathways and discusses potential biomarkers and translational therapeutic strategies to support risk assessment early diagnosis and precision management.
