APEX Managing Modern Athletic Hip Injuries-Online Didactic (September 2021)-Hip Dysplasia and Dysplasia Variants

Video Transcription
It's a pleasure to speak to you today about hip dysplasia and dysplasia variants. I'm Andrea Spiker at the University of Wisconsin. Here are my disclosures.  Today we'll discuss how to define, diagnose, and treat hip dysplasia. I'll also very briefly touch on borderline dysplasia and microinstability.  Dysplasia was first described in the 1800s by Dupuytren, calling it a defect in the depth or completeness of the acetabulum.  Klisik clarified in his paper in 1989 that dysplasia did not necessarily exist at birth and could manifest while the skeleton was developing.  This was integral in changing the terminology from congenital dislocation to developmental dysplasia.  And we now most commonly know this diagnosis as developmental dysplasia of the hip.  Hip dysplasia generally refers to the undercoverage of the femoral head, resultant from the shape, size, or orientation of the acetabulum.  This mismatch results in overloading of the acetabular rim during everyday activities, and patients can develop symptoms of micro or macro instability, fatigue, and pain of  their hip joint. These structural abnormalities can result in labral tears, chondrolabral junction damage, and the development of arthritis.  Hip dysplasia is one of the known predisposing hip pathologies that leads to early hip arthritis along with Skiffy, Perthes, and now FAI.  In 1939, Weiberg compared the shapes of the acetabulae of controls and dysplastic hips and developed the lateral center edge angle.  He showed that those with an LCEA less than 20 degrees were at a higher risk of developing osteoarthritis. This has since been confirmed multiple times over by subsequent studies.
