Hip Dysplasia

What is hip dysplasia?

The hip joints are what allow the legs to move back and forth freely. The hip joint has two major parts: the ball (also called the femoral head) and the socket (the acetabulum). When the components of the hip joint aren't properly formed, the problem is called hip dysplasia. Hip dysplasia could involve a problem with either the femoral head (such as the femoral head being outside the socket) or the acetabulum (such as an acetabulum that is too shallow to fit the femoral head inside it) or both. Hip dysplasia often is a congenital (from birth) condition but also can be acquired after birth. Hip dysplasia is most common in first-born girls, babies with a family history of hip dysplasia, babies born in breech position, or babies who have experienced a lack of intrauterine fluid while in utero.

What are the symptoms of hip dysplasia?

Typically, your baby's physician diagnoses hip dysplasia by using special maneuvers of the hip joint, which are known to cause a clicking in a hip affected by hip dysplasia. If your physician feels the hip clicking, a hip ultrasound will be ordered to assess the hip joint. If hip dysplasia isn't treated, it may lead to pain, arthritis, and the need for a hip replacement later in life.

How is hip dysplasia treated?

In young babies, the treatment is a special brace called a Pavlik harness, which allows the hips to adapt and grow into the correct position. If the Pavlik harness does not work, there are two main options. The first option, for babies generally between six months and one year of age, is a spica cast, which must be placed while your baby is under general anesthesia. The second option, for children over one year of age, is surgery to reshape the hip joint to help the ball and joint fit better together. After surgery, the child will have a spica cast to hold the hip in proper position.
