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. 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. The nerve fibers originate from cervical segments C7 and C8. Purpose: The posterior interosseous nerve (PIN) is closely related to the proximal radius, and it is at risk when approaching the proximal forearm from the ventral and lateral side.

The causes of posterior interosseous nerve syndrome include intrinsic nerve abnormalities and extrinsic compression.

Anterior interosseous nerve syndrome also called Kiloh-Nevin syndrome or anterior interosseous syndrome, is a rare pure motor neuropathy that comprises less than 1% of all upper extremity nerve palsies, arising due to compression or inflammation of the anterior interosseous nerve of the forearm 1). 2009-11-06 · The feasibility of transferring supinator branches to the posterior interosseous nerve has been documented in a previous anatomical study. In this paper, the authors report the clinical results of supinator motor nerve transfer to the posterior interosseous nerve in 4 patients with a C7–T1 root lesion. Posterior Interosseus Nerve (PIN) Syndrome is a compressive neuropathy of the posterior interosseous nerve, a branch of the radial nerve.

Generalized hand weakness is the presenting A complete posterior interosseous nerve palsy resulted from axonotmesis caused by pressure from a ganglion cyst. Excision of the neuroma and interpositional nerve grafting gave a most satisfactory 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.

Explanation of interosseous nerve of forearm, posterior Radial tunnel syndrome (RTS) and posterior interosseous nerve (PIN) compression syndrome are pathologic conditions that are believed to have the same etiology. Τhe former is characterized by chronic elbow and forearm pain radiating to the wrist and dorsum of the hand and fingers, whereas the latter should be considered when weakness or palsy of muscles innervated by the PIN is present.
