ABSTRACT
Injuries to the brachial plexus are uncommon, but are associated with considerable morbidity. Injuries most frequently follow motorcycle accidents or may occur during falls and sporting accidents. Open injuries are rare. The extent of the injury is related to the energy of the trauma-low-velocity injuries are generally neurapraxias with a better prognosis than high-velocity injuries, where an extensive or global defect is associated with a poor outcome.
