It arises from the median nerve just distal to the antecubital fossa, about 5.5 cm distal to the medial epicondyle of the humerus. It passes along the interosseous membrane between the ulna and radius. It terminates in the pronator quadratus muscle around the level of the wrist. It is largely a motor nerve.

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. This anatomic study analyzes the location of the PIN in relation to the proximal radius depending on forearm rotation by means of a novel investigation design. We dissected 21 cadaver elbows to determine the relationship of the posterior interosseous nerve to the posterolateral approach to the elbow and head of the radius.

Methods: This study was based on the dissection of 50 limbs of 25 cadavers, 22 were male and three, female. Age ranged from 28 to 77 years, 14 were white and 11 were non-white; 18 2021-03-01 Looking for interosseous nerve of forearm, posterior?

Explanation of interosseous nerve of forearm, posterior CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The deep branch of the radial (posterior interosseous) nerve courses through the radial tunnel between the superficial and the deep layers of the supinator muscle, where it is liable to undergo compression at various sites, giving rise to the radial tunnel syndrome or the posterior interosseous syndrome.

22 Pronator Anterior interosseous nerve syndrome. 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.

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.

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.

Excision of the neuroma and interpositional nerve grafting gave a most satisfactory 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.
