Common rib injuries after a car accident can include fractures, bruising, and punctured lungs. Rib fractures are the most common type of rib injury and can be caused by the impact of the accident or by the chest being crushed by a collapsing steering wheel or dashboard. Bruising of the ribs can also occur due to the impact of the accident. In more severe cases, a rib injury can result in a punctured lung, which can be life-threatening and requires immediate medical attention.
