Abstract:
Injury to the diaphragm is a marker of severe trauma yet remains one of the most misdiagnosed traumatic lesions. The mechanism may be penetrating (stab or gunshot wounds) or blunt (high velocity injuries). Rupture of the diaphragm may be overlooked due to common associated injuries. Diagnosis is based on strong clinical suspicion and repeated chest x-rays. Current diagnostic tools include CT scan and minimally invasive surgical techniques (laparoscopy or thoracoscopy) in stable patients. These relatively new methods could provide more accurate diagnosis. The main feature of diaphragmatic injury is the incidence of late presentation with the possibility of life-threatening complications such as strangulations may even occur late.

Muscles of the Thorax
The diaphragm is at the core of thoracic musculature, the primary muscle involved in breathing. This expansive, dome-shaped muscle marks the division between the thoracic and abdominal cavities. It originates...
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...
