What causes Adult Hip Dysplasia?
The cause of adolescent and adult hip dysplasia is obscure. Doctors are just becoming aware that infant screening detects only 10% of dysplasia that causes arthritis in adults. Hip instability in babies can usually be detected, but one possibility is that some babies have shallow sockets that fail to develop completely or become unstable at an older age. These would not be detected by current methods. There is increasing interest in identifying and treating babies that have shallow sockets that are currently considered borderline normal. Infant hips that are in the lowest 1% of hip development by measurement are usually treated, but perhaps that needs to be reconsidered so that babies in the lowest 5% by measurement are treated. This would require research to prove that early treatment might help prevent adult arthritis. Also simpler and cheaper methods need to be developed if widespread treatment is used for prevention. The International Hip Dysplasia Institute is on the leading edge of these concerns and is directing some of its research efforts towards discovering new methods of prevention that may be possible.

A better understanding of artificial joint materials and individuals’ responses to them are key to improving hip replacement success.
When osteoarthritis (OA) damages a hip to the point that every movement causes pain, replacing the joint with a prosthesis can restore the ability to function pain-free. But for many people – particularly younger, more active ones – an artificial joint is not a permanent fix. Joint replacements can fail over time, often necessitating further, more difficult surgery. By better understanding what causes hip implants to fail – or alternatively what makes others last – researchers are gaining new understandings that may improve implant longevity and make them an appropriate and lasting option for more people.
While much of the research focuses on materials and design of the implants themselves, researchers are also examining individuals’ responses to implants, says Joshua Jacobs, MD, professor and chairman of orthopaedic surgery at Rush University Medical Center in Chicago. This could lead not only to improvements in design and materials but potentially to tests that could indicate the best implant for an individual before surgery and the use of agents to prevent implant problems after surgery.
