Imaging Radiograph: — Osteopenia — Pencil point cortical thinning — Trummerfeld zone (field of rubble) metaphyseal lucencies — Pelkan spur causing metaphyseal cupping — Frankel line is irregular white line at metaphysis due to dense zone of provisional calcification — Wimberger ring sign is epiphyseal shell with central lucency — Subperiosteal hemorrhage that calcifies with healing
AP and lateral radiographs of the lower extremity show thinned cortices and calcified subperiostial hemorrhage around the distal femurs, left greater than right.
