Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lungs are clear . Cardiac silhouette is top normal in size . There is no pulmonary edema or definite findings to suggest pneumonia . A trace left pleural effusion is difficult to entirely exclude on the lateral view , but no large pleural effusion is seen . No underlying pneumothorax is present . There does not appear to be any rib fractures , but not the best study for evluatio . The complete sternal fracture fragments seem to have slightly further disassociated since hte prior exam and have definitely been getting more displaced since ___ . In addition , there are several vertebral body wedge compression fractures , most pronounced with a near complete wedging of a lower thoracic veterbral body ( ~ T11 ) . Slightly superior to this , there is a further compression of the approximately T8 vertebral body when compared to the ___ exam .
    OUTPUT:
    
1 . Difficult to exclude a trace posterior left pleural effusion , as above , but no large pleural effusion . Clear chest . 2 . Further dissociation of the sternal fracture fragments since the prior exam . Multiple thoracic wedge compression fractures ; the worst of these were present previously , although in the interval since ___ there is continued progressed compression of approximately the T8 vertebral body .
