Radial canal
The radial canal ( Canalis nervi radialis ) is a vascular-nerve road on the upper arm . It lies directly on the humerus and is bounded by this and the lateral and medial head of the triceps brachii muscle . The radial nerve and the deep brachial artery run in the radial canal . Both pierce the upper arm fascia between the brachialis and brachioradialis muscles and thus leave the radial canal.
In the area of the radial canal, fractures of the upper arm shaft cause damage to the radial nerve and thus distal radial paralysis .
