anterior interosseous nerve

It may cause compression of the anterior interosseous nerve.

This reflects involvement of the anterior interosseous nerve.

There is little sensory deficit since the anterior interosseous nerve has no cutaneous branch.

The anterior interosseous nerve is a motor branch of the median nerve, which arises just below the elbow.

Electrophysiologic testing is an essential part of the evaluation of Anterior interosseous nerve syndromes.

Rheumatoid disease and gouty arthritis may be a predisposing factor in anterior interosseous nerve entrapment.

The anterior interosseous nerve classically innervates 2.5 muscles:

This can also refer to Anterior interosseous nerve palsy from compression on the forearm resulting in an inability to flex the index and thumb tips.

Anterior interosseous nerve (AIN) palsy may also be present, but it is often overlooked because there is no sensory component to this finding.

Fibrous bands or arcuate ligaments may entrap the median as well as the anterior interosseous nerves, in which case a patient may experience numbness as well as pain.

Anterior interosseous nerve entrapment or compression injury remains a difficult clinical diagnosis because it is mainly a motor nerve and the syndrome is often mistaken for finger ligamentous injury.

A branch of the median nerve, the anterior interosseous nerve (AIN) can be affected by either direct penetrating injury or compression in a fashion similar to carpal tunnel syndrome.

As it is on the anterior side of the arm, it is innervated by a branch of the median nerve, the anterior interosseous nerve (roots C8 and T1 with T1 being primary).

The syndrome was first described by Parsonage and Turner in 1948 and further defined as isolated lesion of the anterior interosseous nerve by Leslie Gordon Kiloh and Samuel Nevin in 1952.

The anterior interosseous nerve (volar interosseous nerve) is a branch of the median nerve that supplies the deep muscles on the front of the forearm, except the ulnar half of the flexor digitorum profundus.

The anterior interosseous nerve (a branch of the median nerve) and the anterior interosseous artery and vein pass downward on the front of the interosseous membrane between the flexor pollicis longus and flexor digitorum profundus.

Anterior interosseous syndrome or Kiloh-Nevin syndrome I is a medical condition in which damage to the anterior interosseous nerve (AIN), a motor branch of the median nerve, causes pain in the forearm and a characteristic weakness of the pincer movement of the thumb and index finger.

In a pure lesion of the anterior interosseous nerve there may be weakness of the long flexor muscle of the thumb (Flexor pollicis longus), the deep flexor muscles of the index and middle fingers (Flexor digitorum profundus I & II), and the pronator quadratus muscle.
