Shenton's line: The femoral neck and the pubis form a graceful arch. You can visualize an egg shape extending the line on both sides. The neck shaft angle (~ 120 degrees) will look flat if

not seen side -on. This is commonly misidentified as 'valgus'. It isn't. In the inset the leg simply has been rotated from the best neck-shaft viewing projection. Two shallow hips with similar uncovering. But one for sure has acetabular wall deformation as Shenton's Line reveals. That can be made less but securing it = S.L.O.B.
