Abstract

Blount disease is a developmental disorder that affects the proximal growth cartilage of the tibia. It is a rare entity of probable multifactorial origin whose etiology is not clear. It causes a progressive deformity with a bowing of the lower limbs in the form of a genu varum. In the early variant, bilateral involvement is more frequent, so in mild cases it may be difficult to differentiate between the physiological variant. We present the case of a 15-month-old girl of African origin, who has a progressive bilateral genu varum. After a clinical and radiological follow-up, he finally needed surgical correction of the deformity.
