Common Interosseous Artery

The palmar and dorsal (posterior) vessels may arise separately from the ulnar.

A high origin of the common interosseous has been described as arising from the axillary artery.

Palmar interosseous arteries may be so well-developed that they substitute for branches of the ulnar and/or radial arteries

The common interosseous may be a branch of a high radial artery and it may provide the radial artery deep to pronator teres.

A usual anterior interosseous may be absent and be replaced by branches of the radial artery.

It may join the radial artery at the wrist, or if the radial stops short of the carpus the posterior interosseous artery may replace it.

One of the branches of the anterior interosseous is of special interest. The median artery is a long slender artery that arises from the proximal part of the interosseous and supplies the median nerve throughout its course in the forearm. Occasionally (~8%), the median arterial branch is large and continues into the hand, deep to the flexor retinaculum along with the median nerve to join in the formation of the superficial palmar arch. The addition of the median artery to the already numerous and crowded carpal canal components may compress the median nerve and lead to the carpal tunnel syndrome.

The median artery is a persistence of the developmental pattern, in which the median artery maintains the superficial palmar network while the radial and ulnar arteries are developing. It persists as a variant, even after the final form of the development of the radial and ulnar vessels in the hand has occurred. The median artery usually arises from the common interosseous artery or the anterior interosseous.

The recurrent interosseous branch of the posterior interosseous is frequently missing and may be replaced by a branch from the common interosseous artery. The posterior interosseous may give rise to an accessory posterior interosseous; it may also give rise to a superficial external interosseous artery that courses superficial to flexor carpi ulnaris to the wrist.
