An important gene associated with Osteonecrosis is MIR122 (MicroRNA 122), and among its related pathways/superpathways are MicroRNAs in cardiomyocyte hypertrophy and Overlap between signal transduction pathways contributing to LMNA laminopathies. The drugs Clavulanic acid and Amoxicillin have been mentioned in the context of this disorder. Affiliated tissues include bone and bone marrow, and related phenotypes are limbs/digits/tail and skeleton
