The brachial plexus is a bundle of intertwined nerves that stem from the nerve roots in the neck (cervical) and an upper trunk portion of the spinal cord. It creates a network that connects with nerves in the arms and controls the sensation and motion in the arms, wrists, and fingers. The nerves that assist the arms exit the spinal column high in the neck while those which support hands and fingers exit lower in the neck.

A traumatic brachial plexus injury occurs due to sudden damage, compression, stretch, or in most severe cases when nerves are ripped from the spinal cord. The nerves may also be damaged due to cancer or radiation treatment. Babies may also sustain brachial plexus during the delivery process.

    If you suspect any loss of movement or sensation in your hands or arms, it is recommended to see a doctor immediately. Your doctor may order some diagnostic tests to identify potential sites of nerve injury. These tests include:

    • An X-Ray of the shoulder & neck
    • Imaging tests such as CT Scans or MRI
    • Electromyogram or nerve conduction study
    Huntington's Disease


    Mild brachial plexus injuries respond well to nonsurgical treatments such as physical therapy, occupational therapy, corticosteroid injections or creams, medications, etc. In severe conditions when nerves don’t heal on their own or fail to restore the function of hands or arms, surgery is the best option for brachial plexus treatment. Surgical treatments include:

    • Nerve grafts
    • Nerve repair
    • Nerve transfer
    • Neurolysis
