Anatomical Course
The anterior interosseous artery originates as a terminal branch of the common interosseous artery. It runs distally along the anterior surface of the interosseous membrane, alongside the anterior interosseous nerve and beneath flexor digitorum profundus and flexor pollicis longus, which it supplies. As it reaches pronator quadratus, it pierces the interosseous membrane to receive its anastamosis, and travel to the wrist to join the dorsal carpal arch.
Branches
- Median artery
- Palmar branch (given off before piercing the interosseous membrane, joins the palmar carpal arch
Relations
- Anterior interosseous nerve (adjancent)
- Interosseous membrane (posterior)
- Flexor digitorum profundus (anterior)
- Flexor pollicis longus (anterior)
- Pronator quadratus (anterior to volar branch, marks lower border of artery's course in anterior compartment)
