Questions and Answers

What is the significance of an acetabular angle greater than 20 degrees?

  • It implies pincer impingement.
  • It indicates femoral head containment.
  • It signifies mild dysplasia.
  • It suggests retroversion. (correct)

In the context of acetabular angles, what is the implication of a center edge angle (LCEA) greater than 39 degrees?

  • Moderate dysplasia
  • Mild dysplasia
  • Pincer deformity (correct)
  • Pincer impingement

How is acetabular inclination evaluated, and what is considered normal?

  • Evaluated by acetabular roof angle, normal range 3-13 degrees (correct)
  • Evaluated by acetabular index, normal range 33-38 degrees
  • Evaluated by acetabular index, normal range >47 degrees
  • Evaluated by center edge angle (LCEA), normal range >47 degrees
