There are several signs of dislocation. The following are given as 2 examples. Thigh bone seems shorter in one leg than in the other as indicated by the level of the knees in this position. A newborn's hip does not x-ray well because their bones are not dense enough to show up on the images. Ultrasound may be used instead of or along with an x-ray.
Treatment is begun as soon as the problem is recognized.
Early treatment has an excellent success rate. This is accomplished by maintaining the baby's legs in a position known as abduction. The legs are bent up to a ninety degree angle and held out to the side. This is the best position to promote normal hip development. The constant pressure of the ball gradually deepens the socket.
