How is the acetabular index measured?
Traditional methods of measuring acetabular index include Measure the angle between the line connecting the triradiative cartilage of both hips and the line bisecting the lower medial and upper lateral edges of the acetabulum [17] (figure 1).
What is a normal acetabular index?
The normal range is 33º to 38º. An angle of more than 47º can be seen in patients with acetabular dysplasia. Measurements between 39º and 46º are indeterminate. Placing the central beam above or below the pubic bone changes the measurement due to geometric distortion.

How is hip dysplasia measured?

How to measure acetabular anteversion?
The rake angle is between 23 and 24 degrees Degree of an ellipse that bisects the entire acetabular cross-sectionThis means that simply measuring the length of the short ellipse axis and the total length of the cross-section projected along the short axis provides radiographic acetabular anteversion.
What is a shallow acetabulum?
