Brachial plexus is network of nerves responsible for conducting signals from the spine to the shoulder, arm and hand. When an injury is caused to these nerves it is known as brachial plexus injuries. The symptoms of these injuries include limp or paralyzed arm, lack of muscle control in the arm, hand or wrist and a lack of sensation in the arm or hand.
The brachial plexus injuries are caused by a shoulder trauma, tumours or inflammation. A rare syndrome known as Parsonage-Turner syndrome or brachial plexitis can cause the inflammation of the brachial plexus without a shoulder injury. The intensity of brachial plexus can be measured by the type of damage done to the nerves. The most severe type of avulsion is caused when the nerve root is cut from the spinal cord.
Some of the brachial plexus can heal without any treatment. Children who are injured during birth improve or recover by 3 to 4 months of age. The treatment for brachial plexus injuries can include physical therapy and at times surgery.
The prognosis of brachial plexus injury is determined by the type and site of the injury. Recovery cannot be made in cases of avulsion and rupture injuries and only surgical procedures can help a recovery. People with neuroma and neuropraxia injuries can make potential recoveries.
