They are oriented perpendicular to the long axis of the bone, and do not cross the entire bone. It represents insufficiency fractures through unmineralized osteoid in patients with osteomalacia. Common sites include axillary margins of the scapulae, ribs, pubic rami, proximal femurs, proximal ulnae and proximal humerus. Similar changes radiographically may be seen in Pagets disease; however, they are only seen in involved bone and are not generalized. In addition, the lines in Pagets occur on the convex side of the bone(tensile aspect) while in osteomalacia they occur on the concave side (compressive aspect).
