Blount disease is characterized by progressive bowing of the legs in infancy, early childhood, or adolescence. While it is not uncommon for young children to have bowed legs, typically the bowing improves with age. Blount disease is a condition that results from abnormal growth in the upper part of the shin bone (tibia) and requires treatment for improvement to occur. Treatment may involve bracing and/or surgery.  Other causes for Blount disease in young children includes metabolic disease and rickets. Blount disease in teens typically occurs in youth who are overweight. In teens surgery is often required to correct the problem.[1]
