Pseudarthrosis of the clavicle
Abstract:
A 21-year-old active duty soldier presented with right shoulder pain and prominence over his right clavicle, with no history of trauma. He recalled that the deformity had been present for a long time, but only recently became painful. The onset of shoulder pain coincided with the beginning of his military service and the requirement to wear over-the-shoulder equipment such as back packs and load-bearing equipment. Physical examination revealed a prominence over the right midshaft clavicle with tenderness to palpation, full active range of motion of the shoulder, and that he was neurovascularly intact.

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...
