Abstract:
We discovered a unique case of complete cartilaginous duplication of the rib cage in a cadaver, never previously described in the literature. A retrospective review of the patient's medical records revealed an antecedent history of progressive tobacco-related emphysema leading to death from end stage respiratory failure. Prior imaging studies consisting of plain radiographs and computed tomograms of the chest had failed to show several underlying cartilaginous duplications of the rib cage. The clinical significance and the potential contribution of this entity to this patient's clinical course remains unanswered.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
