SIR, Stress fractures can be classified into two groups. Fatigue fractures may occur when repetitive muscular forces or stresses are applied to a normal bone, and are most common in adolescents, athletes and military recruits. In contrast, insufficiency fractures are found when physiological forces are applied to a weakened bone in patients with diseases like osteomalacia, fibrous dysplasia, metabolic disease and osteoporosis [1, 2]. Patients with juvenile idiopathic arthritis (JIA) accumulate a number of risk factors for the development of osteoporosis, such as inactivity and treatment with steroids or methotrexate
