THE TERM Saturday night palsy has become synonymous with radial nerve compression in the arm pal tunnel syndrome, posterior interosseous nerve syndrome, cubital ulnar, and radial nerves.

The ratio of axons between the thenar branch of the median nerve and the anterior interosseous nerve yielded a mean of 1:4.16. Posterior Interosseous Nerve (PIN) Palsy is a syndrome characterised by a reduction in extensor movements of the fingers. It most commonly due to a compression at the radial tunnel.

In parts of the medical community, Radial Tunnel Syndrome and PIN Syndrome are one in the same, while in other parts they are different diagnoses with the same nerve involvement (Posterior Interosseous Nerve). Posterior interosseous nerve syndrome is a compressive neuropathy of the posterior interosseous nerve which innervates the extensor compartment of the forearm. It usually has an insidious onset, often presenting with weakness in finger and thumb extension.
It usually has an insidious onset, often presenting with weakness in finger and thumb extension. The posterior interosseous nerve runs in close proximity to the posterior interosseous artery, which also passes along the posterior aspect of the interosseous membrane. The posterior interosseous artery is the principle artery supplying the middle third of the posterior compartment of the forearm. The posterior interosseous artery is eventually replaced by the anterior interosseous artery that pierces the interosseous membrane at the proximal aspect of the pronator quadratus muscle.

It carries fibers from the C7 and C8 spinal nerves, and supplies the majority of the muscles in the posterior compartment of the forearm. The posterior interosseous nerve is a branch of the radial nerve, which comes off the posterior cord of the brachial plexus. The radial nerve, with nerve roots C5 to T1, travels down the arm and divides into superficial and deep branches in the proximal forearm.
The anterior interosseous nerve is a branch of the median nerve that supplies the deep muscles on the anterior of the forearm, except the ulnar half of the flexor digitorum profundus. Its nerve roots come from C8 and T1. It accompanies the anterior interosseous artery along the anterior of the interosseous membrane of the forearm, in the interval between the flexor pollicis longus and flexor digitorum profundus, supplying the whole of the former and the radial half of the latter
Posterior interosseous nerve syndrome is an entrapment of the deep branch of the radial nerve just distal to the elbow joint, which may result in paresis or paralysis of the digital and thumb extensor muscles. The causes of posterior interosseous nerve syndrome include intrinsic nerve abnormalities and extrinsic compression. It is posterior interosseous nerve.

Posterior Interosseous Nerve (PIN) Syndrome is a pathology that involves pain and/or motor weakness as a result of nerve compression. In parts of the medical community, Radial Tunnel Syndrome and PIN Syndrome are one in the same, while in other parts they are different diagnoses with the same nerve involvement (Posterior Interosseous Nerve). The anterior interosseous branch had a mean density of axons per fascicle mm2 of 2398 ± 829 vs. 3012 ± 740 in the thenar branch (p = 0.390). The ratio of axons between the thenar branch of the median nerve and the anterior interosseous nerve yielded a mean of 1:4.16. The posterior interosseous nerve and the posterolateral approach to the proximal radius J. D. Witt, S. Kamineni From the Middlesex Hospital and University College London Hospitals Trust, London, England We dissected 21 cadaver elbows to determine the relationship of the posterior interosseous nerve to the posterolateral approach to the elbow The anterior interosseous nerve (AIN) is the largest motor branch of the median nerve, arising 2–8 cm distal to the medial epicondyle. 5 It innervates the flexor digitorum profundus I and II, flexor pollicis longus (FPL), and pronator quadratus (PQ) muscles.

Variant The posterior interosseous nerve (or dorsal interosseous nerve) is a nerve in the forearm. It is the continuation of the deep branch of the radial nerve, after this has crossed the supinator muscle. It is considerably diminished in size compared to the deep branch of the radial nerve.
