What is Hip Dysplasia?

Hip Dysplasia means that the bones of the hip joint are not aligned correctly. It affects thousands of children and adults each year and is known by many different names: Developmental Dysplasia of the Hip (DDH), Hip Dislocation, Congenital Dislocation of the Hip (CDH), Loose Hips. Hip Dysplasia prevents the hip joint from functioning properly and the joint wears out much faster than normal, much like a car’s tires will wear out faster when out of alignment. It is also a “silent” condition that means pain is not normally felt until much later stages, making it harder to detect. Developmental Dysplasia of the Hip (DDH) – is commonly used when talking about hip dysplasia in children. Approximately 1 out of 6 newborns will have some type of hip instability and 2-3 out of every 1,000 infants will require treatment. In spite of the frequency of DDH in babies and the potential for life-long disability caused by DDH, the awareness of this condition is poor outside of the medical profession. Early diagnosis, prevention, and simple treatment is the best solution, however many hip dislocations are difficult to treat with the current methods of care. Adults with hip dysplasia – is the most common cause of hip arthritis. A 2008 study from Norway showed that more than 90% of these young adult cases couldn’t be diagnosed in childhood by current methods of screening. This suggests that new methods for prevention or early detection need to be developed. Research by the International Hip Dysplasia Institute aimed towards finding solutions for this problem of hidden hip dysplasia.
