The authors investigated the effect of x-ray tube head angulation and central ray direction on the position of the first metatarsal relative to the second metatarsal in the lateral foot radiographic view. This preliminary study shows that these variables may influence the perception of metatarsus primus elevatus in the weightbearing lateral foot radiograph. (J Am Podiatr Med Assoc 91(6): 294-299, 2001)
