Lap/shoulder belts are known to produce abdominal (most common), thoracic, and spinal injuries. The “seat belt sign,” abrasions or ecchymoses to the neck, chest, and abdomen in the pattern of the belt, occurs in less than 20% of patients but is associated with a fourfold risk of intrathoracic and an eightfold risk of intra-abdominal injury.
