Quick Facts
Origin: Ulnar artery.
Course: Descends to proximal edge of the interosseous membrane.
Branches: Anterior and posterior interosseous arteries.
Supplied Structures: Cubital fossa, deep part of the anterior compartment of the forearm, and the posterior compartment of the forearm.
Origin
The common interosseous artery arises from the ulnar artery. It originates close to the origin of the ulnar artery within the cubital fossa.
Course
The common interosseous artery has a short inferior course from the distal portion of the radial tuberosity to the proximal edge of the interosseous membrane.
Branches
The common interosseous artery terminally bifurcates into the anterior interosseous artery and the posterior interosseous artery.
Supplied Structures
The common interosseous artery contributes to the supply of the cubital fossa. Additionally, in contributes to the blood supply of the deep part of the anterior compartment of the forearm and the posterior compartment of the forearm.
