I was told that Blount’s disease was a rare disease, but we have two kids in our family with it. Were we just unlucky?

Blount’s disease, a bone disorder that causes bowing of the legs, is not a common disease. There are some risk factors that have been identified and if you take them all into account, it is possible for more than one child in a family develop Blount’s disease. In fact, family history is a risk factor in itself. The risk factors include:

Being a girl
Being African American
Being oveweight for the child’s age
Walking earlier than expected
Family history
