The brachial plexus is a network of nerves that originate near the neck and shoulder. The nerves begin at the spinal cord in the neck area and control the shoulder, elbow, wrist, and hand. When the brachial plexus is injured certain symptoms will arise depending on where in the network of nerves the injury has occurred. These nerves are in a fragile area and can be damaged by pressure, stretching, or cutting. An example of a stretching injury occurs if one were to fall from a tree and grasp a branch on the way down. The force of stretch between the arm and the body can cause the nerves at the lower end of the network to become damaged. Injuries may range from minor, where recovery will occur completely, to severe, where permanent disability can be expected. Treatment goals are to restore nerve function.
