  Flail chest (동요가슴, 연가양흉곽)은 추락, 기계사고, 총기 사용, 교통사고 등으로 발생하며, 3개 이상의 인접한 갈비뼈가 2군데 이상에서 골절되어 발생하는 흉벽의 불안정한 움직임을 말한다. 이로 인해 호흡 시 흉벽이 정상적으로 움직이지 못하여 저산소증, 고탄산증, 호흡부전 등이 발생할 수 있다. 치료는 호흡기능 장애 정도에 따라 달라지며, 통증 관리, 기침과 심호흡 증진, 기계환기 등이 포함된다. 수술적 고정술은 논란의 여지가 있지만, 다른 손상으로 흉곽 수술이 필요한 경우 시행할 수 있다.

  Flail chest, also known as 'dynamic chest' or 'paradoxical chest wall motion', is a serious and potentially life-threatening condition that occurs when a segment of the chest wall becomes detached from the rest of the chest wall due to multiple rib fractures. This results in the affected segment moving paradoxically, or in the opposite direction, from the rest of the chest wall during breathing. This can lead to severe respiratory distress and impaired gas exchange, as the detached segment is unable to contribute effectively to the mechanics of breathing. The primary cause of flail chest is severe blunt trauma to the chest, such as from a motor vehicle accident, fall from height, or other high-impact injury. The multiple rib fractures that occur can cause the chest wall to become unstable and 'flail' during respiration. Patients with flail chest often present with severe pain, difficulty breathing, and paradoxical chest wall motion that is visible on physical examination. Management of flail chest typically involves a combination of pain control, respiratory support, and stabilization of the chest wall. This may include the use of mechanical ventilation, positive pressure ventilation, and even surgical stabilization of the fractured ribs in some cases. Prompt recognition and appropriate treatment are crucial, as flail chest can rapidly lead to respiratory failure and other life-threatening complications if not properly managed. Overall, flail chest is a serious and complex injury that requires a multidisciplinary approach to treatment. Ongoing research and advancements in trauma care continue to improve outcomes for patients with this condition.
