It was described as the branch that emerges from the median nerve or anterior interosseous
nerve (branch of the median nerve) and moves towards the ulnar nerve, containing fibers dedicated to the intrinsic musculature of the hand.
Following three patients presented with motor deficits in addition to sensory symptoms in the upper extremity due to compression of the radial nerve, anterior interosseous
nerve and posterior interosseos nerve respectively.
Of these, 18 patients resolved on the first post-operative day, while 12 patients recovered at 3 months and 2 patients at 6 months follow-up; after a year, 1 persisted with anterior interosseous
nerve (AIN) palsy.
He used anterior interosseous
nerve end to pronator quadratus for end to side coaptation to deep motor fascicle to ulnar nerve in distal forearm for intrinsic hand function restoration.
(7) Exclusion of other diseases (e.g., motor neuron disease, multifocal motor neuropathy, brachial plexopathy, spinal cord tumors, syringomyelia, cervical vertebral abnormalities, anterior interosseous
, or deep ulnar neuropathy)
nerve (AIN) neuropraxia, also known as anterior interosseous
syndrome, presents clinically as the inability to flex the distal phalanges of the thumb and index finger as well as possible weakness in pronation, all resulting from the paralysis of flexor pollicis longus (FPL), flexor digitorum profundus (FDP) to the index finger, and pronator quadratus (PQ).
From these patients 5 cases with damage of anterior interosseous
nerve were selected (the pseudoanterior interosseous nerve syndrome)  and 6 patients presented damage of the ulnar nerve, and radial nerve injury occurred in 1 child, which accounted for 27% and 5% of all damage to the nerves.
 The presence of a PMA may result in several complications such as CTS, digital ischemia, pronator syndrome, or anterior interosseous
 Anterior interosseous
artery, a branch of ulnar artery gives nutrient branches to radius and ulna.
One of the nerves leading to a muscle was taken and attached to the anterior interosseous
nerve, which goes to the hand.
The pulse will be missing in about 10% of the type III fractures, usually due to injury of the medial nerve and the anterior interosseous
branch of the medial nerve.
It arises from the distal third of the medial surface of the fibula, the adjacent anterior interosseous
membrane and the anterior intermuscular septum.
