Abstract
The brachial plexus is charged of the sensitive and motor innervation of the superior limb group. It is constituted of the union of the anterior branches of the last four cervical nerves (C5, C6, C7 and C8) and of the first thoracic nerve root (T1). Sometimes there is a significant amount of fibres coming from C4 or T2. Brachial plexus injuries are frequent in newborn children because of obstetric traction and in young adults mainly because of lower cervical spinal trauma. The plexus brings the spinal roots together in trunks, themselves splitting into divisions and cords.
