What is Hip Dysplasia?

  • Hip Dysplasia means that the bones of the hip joint are not aligned properly.
  • Hip Dysplasia affects thousands of children and adults each year.
  • Hip Dysplasia has many different names:
    • Developmental Dysplasia of the Hip – DDH
    • Congenital Dislocation of the Hip – CDH
    • Neonatal Hip Instability – NHI
    • Acetabular Dysplasia
  • Hip Dysplasia prevents the hip joint from working properly and the joint wears out much faster than normal, much like a car’s tires will wear our faster when out of alignment.
  • Hip Dysplasia also begins as a “silent” condition so that pain is uncommon until later stages. This makes Hip Dysplasia harder to detect and more difficult to treat unless detected.
