Center edge angle of Wiberg

Last revised by Dr Yuranga Weerakkody on 13 Feb 2022

The center-edge angle (CEA) of Wiberg is a measurement in the pelvis which is the angle formed by Perkin line and a line from the center of the femoral head to the lateral edge of the acetabulum. It can be used to assess for conditions such as developmental dysplasia of the hip although only considered reliable in patients > 5 years of age. An angle of < 20° is considered abnormal.
