In which type of trauma is a “seatbelt sign” an indicative finding?

A "seatbelt sign" is an indicative finding primarily associated with abdominal injuries. This sign refers to the pattern of bruising or abrasions on the abdomen and lower chest, resembling the shape and position of a seatbelt, and it occurs when a person is involved in a car accident and restrained by a seatbelt.

The presence of a seatbelt sign is significant in trauma assessment because it suggests potential underlying injuries, particularly to solid organs like the liver or spleen. These organs are at risk of laceration or contusion from the forces applied during a collision, and the sign can indicate the need for further diagnostic imaging or intervention.

Recognizing the seatbelt sign emphasizes the importance of a thorough examination in trauma cases, as it can guide the clinician toward possible intra-abdominal injuries that might not be immediately apparent. Hence, identifying a seatbelt sign calls for careful consideration and likely further evaluation in the context of abdominal trauma.
