What term describes a section of ribs that have been broken and detached from the chest cavity?

A flail segment refers to a section of ribs that becomes detached from the chest cavity, usually as a result of multiple rib fractures. This condition is significant because the detached segment moves independently from the rest of the rib cage, often leading to impaired respiratory function and severe pain. During breathing, instead of moving outward with the chest cavity, the flail segment may move paradoxically inward, which can exacerbate respiratory distress. Recognizing a flail segment is essential for appropriate management and intervention in traumatic situations. The other terms mentioned, like dislocation, sprain, and strain, refer to injuries affecting joints, ligaments, or muscles, and do not pertain to the detachment of rib segments in the context of thoracic injuries. Understanding this terminology is critical for assessing and managing trauma patients effectively.
