The deep branch provides motor function to the muscles in the posterior compartment of the forearm, which is mostly the extensor muscles of the hand. The radial nerve arises from the posterior cord of the brachial plexus. The posterior cord takes nerves from the upper, lower, and middle trunk, so ultimately the radial nerve is formed from the ...
The radial nerve is the largest nerve of the upper limb. It originates from the posterior cord of the brachial plexus and divides into deep and superficial branches in the cubital fossa. The deep branch supplies the posterior muscles of the forearm and wrist.

The deep branch of the radial nerve normally passes between the supinator's heads, where it becomes the posterior interosseous nerve and innervates the posterior forearm muscles. However, in some individuals, the deep branch of the radial nerve passes through the arcade of Frohse (supinator arch), which can increase the likelihood of impingement.
The deep branch of the radial nerve or posterior interosseous nerve, is entirely motor. It begins anterior to the lateral epicondyle of the humerus and enters the posterior compartment of the forearm through the two heads of supinator where it curves around the lateral and posterior surfaces of the radius. It descends between the deep and ...

The radial nerve divides into a deep branch, which becomes the posterior interosseous nerve, and a superficial branch, which goes on to innervate the dorsum (back) of the hand. This nerve was historically referred to as the musculospiral nerve. Structure Radial nerve of the right axilla, posterior view ...
The deep branch of radial nerve supplies the brachioradialis and extensor carpi radialis longus muscles, and then descends between the two heads of supinator muscle. Once the deep branch exits underneath the supinator muscle, it is referred to as the posterior antebrachial interosseous nerve. The superficial branch is given off inside the ...
The Deep Branch of the Radial Nerve (n. interosseus dorsalis; dorsal or posterior interosseous nerve) winds to the back of the forearm around the lateral side of the radius between the two planes of fibers of the Supinator, and is prolonged downward between the superficial and deep layers of muscles, to the middle of the forearm. Considerably diminished in size, it descends, as the dorsal ...
Learn about the deep branch of radial nerve, which supplies the dorsal muscles of the upper limb. Find out its origin, course, and relation to the supinator muscle and the forearm.
Type: The radial nerve is a mixed nerve, consisting of both motor and sensory fibers. Origin: It originates from the posterior cord of the brachial plexus, generally deriving fibers from the C5 to T1 nerve roots. Branches: The nerve gives off several branches along its course, including branches to the triceps, the cutaneous branches to provide ...
deep branch of the radial nerve: direct innervation to the extensor carpi radialis brevis and supinator muscles; continues as the posterior interosseous nerve to supply the deep extensors of the dorsal arm (extensor digitorum, extensor digiti minimi, extensor carpi ulnaris, extensor indicis, extensor pollicis longus, extensor pollicis brevis ...
The Radial Nerve (n. radialis; musculospiral nerve), the largest branch of the brachial plexus, is the continuation of the posterior cord of the plexus.Its fibres are derived from the fifth, sixth, seventh, and eighth cervical and first thoracic nerves.It descends behind the first part of the axillary artery and the upper part of the brachial artery, and in front of the tendons of the ...
The radial nerve is the biggest branch of the posterior cord of the brachial plexus and one of its five terminal branches. Entrapment of the radial nerve at the elbow is the third most common compressive neuropathy of the upper limb after carpal tunnel and cubital tunnel syndromes. Because the incidence is relatively low and many agents can ...
Introduction. The deep branch of the radial nerve (DBRN) is one of the major divisions of the radial nerve in the elbow region. DBRN entrapment occurs primarily at the level of the superior arcade of the supinator muscle (SASM), which is also known as the arcade of Frohse [].An association between DBRN entrapment, SASM, and repetitive rotational forearm movements has been previously proposed ...
Course. The superficial radial nerve originates in the cubital fossa as the radial nerve divides into superfical and deep branches at the level of the lateral epicondyle.. It continues down the anterior aspect of the forearm, lateral to the radial artery, and concealed in a plane between the brachioradialis and pronator teres muscles.. About 7cm proximal to the wrist, it pierces the deep ...
The posterior interosseous nerve is the deep branch stemming from the radial nerve. Compression can be caused by trauma, repetitive strain and inflammation. This is then known as posterior interosseous nerve syndrome, which may result in paresis or paralysis of the digital and thumb extensor muscles, resulting in an inability to extend the ...
Entrapment of the deep branch of the radial nerve (DBRN) results in two distinct clinical syndromes.Posterior interosseous nerve syndrome (PINS) is a well-defined but rare nerve palsy involving some of the wrist extensors and all of the finger extensors [1, 2].By contrast, radial tunnel syndrome (RTS) is a controversial, painful repetitive stress type of injury without "hard" neurologic ...
Radial nerve entrapment is an uncommon diagnosis that is prone to under-recognition. Compression or entrapment can occur at any location within the course of the nerve distribution, but the most frequent location of entrapment occurs in the proximal forearm. This most common location is typically in proximity to the supinator and often will involve the posterior interosseous nerve branch.
Along its course, the deep brachial artery follows the radial nerve. Together with the nerve, it traverses the radial groove of humerus in the posterior arm, where it is covered by the long head of triceps brachii. Under the long head of triceps, the artery splits into its two terminal branches; radial collateral and middle collateral arteries.
The deep branch of the radial nerve (DBRN) is one of the major divisions of the radial nerve in the elbow region. DBRN entrapment occurs primarily at the level of the superior arcade of the supinator muscle (SASM), which is also known as the arcade of Frohse [].An association between DBRN entrapment, SASM, and repetitive rotational forearm movements has been previously proposed [1,2,3,4].
Course: The radial nerve branches into the superficial branch and deep branch, also known as the posterior interosseous nerve, in the deep posterior proximal compartment of the forearm. The superficial branch continues distally and arises superficially between the brachioradialis tendon and the extensor carpi radialis longus tendon within the mid-forearm.
A patient is described, who was severely debilitated by compression of the superficial branch of the radial nerve that she was unable to work and should be considered a rare cause of Wartenberg's syndrome. Wartenberg's syndrome is a compression sensorineural mononeuropathy of the superficial branch of the radial nerve. This case report describes a patient, who was severely debilitated by ...
