Overview

The upper trunk (or superior trunk) is a trunk of the brachial plexus which derives from the C5 and C6 roots.

Damage to the upper trunk causes

  • Arm hangs by side,
  • Elbow can’t flex,
  • Arm medially rotated,
  • Forearm pronated,
  • ‘waiter’s tip’,
  • Loss of sensation over deltoid (C5) and lateral upper limb (C6).

The musculocutaneous and median nerves derive largely from this trunk.
