[Chest Wall Injury].

ABSTRACT

A traumatic chest wall injury is a condition that is often encountered in medical practice, but the underlying pathophysiology varies widely depending on the circumstances of the injury and the patient's background. The chest wall, which protects vital organs and provides respiratory movement, can be a life-threatening emergency when injured, thus it is important to respond promptly and appropriately. Because a penetrating chest wall trauma is often associated with intra-thoracic organ damage, it is important to consider an emergency thoracotomy in cases involving massive hemorrhage or air leakage. The ribs and sternum are primarily injured in patients with blunt wall trauma. Flail chest, which is defined as multiple bifocal fractures of the ribs or multiple rib fractures with a sternal fracture, causes respiratory failure secondary to paradoxical respiration. The main treatment for flail chest is ventilatory care and surgical treatment, although early rib fixation has been reported to improve prognosis in recent years. There are several types of devices to fix the ribs and sternum, but selection criteria have yet to be established.
