    The mentioned fractures were pathologic fractures caused by metastases. 
    Primary tumours 
    e.g. breast cancer, bronchial carcinoma, carcinoma of the kidney or thyroid 
    usually metastazise to the skeleton, especially the axial skeleton and cause 
    lytic lesions in the bone. Whereas sclerotic lesions are usually caused by 
    prostatic carcinoma.Those 
    tumours which disseminate to the distal extremities usually arise from the 
    bronchus or the breast. 
    Other causes of pathologic 
    fractures are e.g. at an early age osteogenis imperfecta, rickets or osteomalacia 
    (either intestinal or renal tubular disorders). Always consider Cushing`s 
    syndrome, hyperparathyroidism and after the menopause osteoporosis.
