Abstract:
Severe trauma to the brachial plexus most often occurs in young adult men and is a crippling injury that requires management in a timely fashion for optimal functional recovery and pain control. The surgical management of such injuries is well established, and the techniques continue to evolve. Current management options consist of primary repair in the acute setting, neurolysis, neuroma resection and nerve grafting, motor and sensory nerve transfers, and muscle and tendon transfers. Shoulder andwrist fusion can also play a role in the overall management of these patients. The best operative plan varies depending on the patient's level and extent of injury and the surgeon's preference and experience. The pre- and postoperative care of these patients is ideally managed by a team that has experience with such problems, including personnel knowledgeable in their postoperative rehabilitation. The total reconstructive process generally consists of more than one operation, and the postoperative rehabilitation is long and intensive. Nevertheless, with a highly motivated patient and a dedicated and specialized surgical team, the prognosis for functional recovery is good, and these patients can still lead productive and satisfying lives.

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...
