Among them, joint examination is particularly critical to the normal development of a fetus baby, such as developmental hip joint examination, where developmental hip joint dislocation is a birth-related hip joint developmental disorder, commonly called congenital hip joint dislocation. Because the acetabulum fails to normally develop in the embryonic period, the shape of the acetabular bone top is changed, the acetabular bone top cannot well cover the femoral head, and the femoral head is displaced after birth or not, so that the acetabulum and the femoral head cannot normally develop, and finally, the hip joint undergoes a series of irreversible pathological changes. If the B-ultrasonic is used in the early stage to check the development conditions of the hip joints of the neonate and the infant in time, the judgment can be made in time, so that the neonate can catch up with the best treatment opportunity, and the acetabulum can normally develop and even heal.
