The extrusion index is a radiographic measurement of femoral head bony coverage by the acetabulum. It is useful in assessing for developmental dysplasia as well as femoroacetabular impingement. It is calculated by dividing the horizontal distance of the lateral femoral head that is uncovered by...
Lateral center-edge angle
The lateral center-edge angle is a radiographic measurement of femoral head bony coverage by the acetabulum. It has primarily been described in assessing for acetabular dysplasia but can also be used in femoroacetabular impingement. It is calculated on AP pelvic radiographs by using drawing a b...
