Criteria: Angle of intersection should not exceed standards based on age. In adults, the normal range is 33-38º. Angle above 47º suggests acetabular dysplasia.

Angles above 47º are seen in patients with acetabular dysplasia. A measurement between 39º and 46º is indeterminate.
One study showed that adult patients with hip dysplasia may see more than three A common measurement for the depth of the socket is the center-edge angle.
