Introduction: Blount disease is an asymmetrical disorder of proximal tibial growth that produces a three-dimensional deformity. Tibia vara is the main component of the deformity. There is general agreement that two clinical forms should be distinguished based on age, infantile and adolescent, with 10 years as the cut-off. Case: We present a case of 11 year old girl admitted to our radiology department with chronic bilateral gonalgia and genu varum evoluting for a year. The clinical examination reveals bilateral varus deformity of the proximal tibia, a palpable prominence or “beaking” of the proximal medial tibial epiphysis and metaphysic. The diagnosis of blount disease has been confirmed on standard radiography. Conclusion: Blount's disease remains a rare disease whose etiology is still unknown, seems to involve hereditary and environmental factors explaining its very particular distribution. Radiological investigations are helpful to the diagnosis by showing medial varus malalignment of the tibial metaphysis. Many angles have been described. A mongthem, the mostuseful are the mechanical tibio-femoral angle, metaphyseal-diaphyseal angle (MDA) of Levine and Drennan, and bony tibial slope.
