KEY FACTS

  • Terminology

    • Imaging

      • Top Differential Diagnoses

        • Clinical Issues

          TERMINOLOGY

          • Synonyms

            • Congenital hip dysplasia: Term no longer used, since condition may develop in early life rather than being present at birth
          • Definitions

            • Developmental dysplasia of hip (DDH) covers wide spectrum of disease
            • Failure of modeling of acetabulum
              • Most severe: Complete hip dislocation, shallow native acetabulum, formation of pseudoacetabulum superolateral to native position
              • Intermediate: Shallow acetabulum with increased acetabular angle
              • Most mild: Elevation of lateral margin of acetabular roof (sourcil)
            • Acetabular retroversion seen in pincer-type femoroacetabular impingement is also form of dysplasia
              • Often called acetabular dysplasia to distinguish from classic DDH
