The main cause of this condition happens when the soft cartilage that slowly hardens into bone in the ball and socket must fit together, but if the ball is not connected firmly enough in the socket, the socket will completely form around the ball and it will become too shallow. Risk factors associated with this condition are: higher in babies born in the breech position, huge babies and babies that have foot deformities.
Signs and symptoms of this condition include: one hip may be less flexible than the other, one leg may be longer than the other leg, you may notice a limp when the child starts to walk, and activity-related pain in the groin area.
