Which term means that no signs of trauma are present?

The term "atraumatic" is specifically used in medical contexts to describe a situation or condition where there are no signs of trauma, injuries, or physical damage present. This term is often used during examinations or assessments to indicate that the area being examined appears normal and unaffected by external force or injury. For example, a medical professional might document that a patient's examination findings are atraumatic, ensuring that there are no visible cuts, bruises, or other indications of trauma.

In contrast, "abrasive," "laceration," and "ecchymosis" all relate to signs of injury or trauma. An abrasive describes a substance that can cause wear or damage, typically not used in the same context as physical trauma to a person. A laceration is a specific type of injury that involves a cut or tear in the skin, indicating clear signs of trauma. Ecchymosis refers to a discoloration of the skin resulting from bleeding underneath, commonly known as a bruise, which also indicates previous trauma. Thus, only the term atraumatic clearly signifies that no signs of trauma are present.
