Familial Mediterranean fever (FMF) is a monogenic autoinflammatory disorder that is linked to homozygous mutations of the MEFV gene [1]. The field of FMF is expanding as many patients with FMF phenotype are heterozygous with monoallelic variants. Arthritis is a frequent manifestation of FMF, involving 50 to 75% of patients [2]. The hip is the third most commonly affected joint after the knee and ankle [2]. Aseptic necrosis of the femoral head [3] caused by disruption of local blood supply has also been reported in FMF patients.
