Is there a risk of causing hip dyplasia in infants by carrying them in front packs?

Hip dysplasia is a congenital malformation of the hip joint in infants.  Studies have led us to believe that the condition can be inherited and in many cases the hip dysplasia can be diagnosed in utero.  The best position for a baby with this condition is legs spread wide, with knees bent.  In this position, the joint is encouraged to ossify in a more integrated position.  There is no risk of causing this condition by carrying your baby in any of the front packs on the market.  ERGO baby carriers are unique, thoug, in that they are designed to carry baby in this optimal position, legs spread wide, knees bent.
