Both cleft palate and hip dysplasia are congenital abnormalities affecting skeletal formation. A cleft palate occurs if the fusion of the midline of the maxilla fails to occur. Problems may range from simple cosmetic abnormality to a complete lack of separation of the nasal and oral cavities. In such a case, the infant will have difficulty taking in food, and may even aspirate it, due to a lack of a palate to regulate breathing and swallowing. Hip dysplasia occurs if the acetabulum fails to form a complete socket around the head of the femur correctly, or if the ligaments securing the femur at the hip are too loose. The femur may easily slip out of its socket, creating difficulty walking.
