Radiographic Markers of Femoroacetabular Impingement: Correlation of Herniation Pit and Femoral Bump with a Positive Cross-Over Ratio

<table>Illustration of the method used to calculate the overlap-ratio A : B. Distance A (extending from the lateral border of the acetabulum to the point where the anterior rim crosses the posterior rim) and distance B (extending from the lateral border of the acetabulum to its posteroinferior border).</table>
