"The lateral centre-edge angle was first described by Wiberg and is calculated on AP pelvic radiographs by drawing a best-fit circle for the inferior and medial margins of the femoral head. The angle is then measured between two lines drawn from the centre of the circle, one running vertically along the longitudinal axis of the body (perpendicular to a line joining the inferior ischial tuberosities) and the other to the lateral acetabular rim 7,9."
"Gunnar Wiberg (1902-1988), a Swedish orthopaedic surgeon, first described the lateral centre-edge angle in 1939 9,10."
