<unk>  is a common result of penetrating trauma but may also be caused by blunt trauma; broken ribs may perforate the lung, or the tissue may be torn due to shearing forces that result from different rates of acceleration or deceleration of different tissues of the lung. Violent compression of the chest can cause lacerations by rupturing or shearing the lung tissue.<unk>  may result from blunt and penetrating forces that occur in the same injury and may be associated with pulmonary contusion. Lacerations of the lung tissue can also occur by compression of the alveoli against the ribs or spine. As with contusions,<unk> s usually occur near solid structures in the chest such as ribs.<unk>  is suspected when rib fractures are present.
