Can you guess the diagnosis?


The answer is Flail chest
.
Flail chest occurs when trauma to the chest causes multiple fractures in ≥ 3 adjacent ribs with a segment of the chest wall separating from the rest of the thoracic cage; it is a marker for injury to the underlying lung.
.
When a patient has a flail chest, the flail segment moves paradoxically (i.e, outward during expiration and inward during inspiration).
.
A chest x-ray can help confirm bone fractures and usually shows underlying pulmonary contusion.
.
Some modalities of treatment include: supportive care; sometimes mechanical ventilation and occasionally rib fracture repair and analgesics.
