Radial canal

from Wikipedia, the free encyclopedia

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 .
