Abstract:
A 7-year-old girl presented with an asymptomatic right supraclavicular swelling. Radiographs were interpreted as showing a non-union of her clavicle. No treatment was given at this time. However, she represented 12 years later with right upper limb pain and altered sensation. Examination revealed a positive Allen's test on the right. Repeat radiographs demonstrated a pseudarthrosis of the clavicle, associated with a secondary complication of thoracic outlet syndrome with vascular and neurological complications present. Non-operative management failed to relieve her symptoms. Operative intervention successfully treated her symptoms.

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...
