Obturator ring 은 column or T shaped Fx

Ilioischial lines 은 posterior column, T shaped, Transverse

Iliopectineal line 은 anterior column, T shpaed, Transverse

Iliac wing Fx 은 ant column fracture

posterior wall Fx 는 말그대로 post wall 만

Spur sign 은 both column fracture 에만 관찰가능 (internal oblique view = obturator view)
