Developmental Dysplasia of the Hip

Developmental Dysplasia of the Hip or DDH is a term that describes hip conditions resulting from an abnormal relationship between the femoral head and the hip joint socket. If the head is not seated appropriately in the socket (the acetabulum), the joint will not develop normally. In infants, the hip joint may be completely dislocated, or just loose, with the head slipping within the acetabulum.
