Key words: Anconeus, pedicle muscle flap, anatomy, coverage area. The elbow joint is covered by a thin, elastic, soft tissue envelope. This envelope can be compromised after septic olecranon bursitis, injury, tumor resec- tion, or a failed extensor origin release.
What is the function of the Anconeus muscle?
Function. Functionally the anconeus fulfills the same tasks at the elbow as the triceps muscle. Its contraction leads to the extension of the forearm. Furthermore, it keeps the tension of the dorsal joint capsule, thus preventing damages during hyperextension.
What is the blood supply of the anconeus?
The anconeus muscle is supplied from 3 arterial pedicles: the recurrent posterior interosseus artery, the medial collateral artery, and the posterior branch of the radial collateral artery.
Is anconeus a flexor?
The anconeus muscle (or anconaeus/anconæus) is a small muscle on the posterior aspect of the elbow joint. Some consider anconeus to be a continuation of the triceps brachii muscle. …
| Anconeus muscle | |
|---|---|
| Origin | lateral epicondyle of the humerus proximally |
What artery supplies Supinator?
| Supinator muscle | |
|---|---|
| Origin | Lateral epicondyle of humerus, supinator crest of ulna, radial collateral ligament, annular ligament |
| Insertion | Lateral proximal radial shaft |
| Artery | Radial recurrent artery |
| Nerve | Deep branch of the radial nerve |
What artery supplies brachioradialis?
The radial recurrent artery provides blood supply to the elbow joint, brachialis, brachioradialis, and other forearm muscles.
How does anconeus work?
The “anconeus sidekick” is a relatively simple exercise: kneel down alongside a bench, using it to support your upper arm, leaving it at right angles to your body, parallel to the floor. Your forearm should then be hanging straight down.
Why is it called anconeus?
The anconeus is a small, triangular muscle of the arm. It is located at the posterior aspect of the elbow, extending from the distal humerus to the proximal ulna. … Anconeus muscle.
| Origin | Lateral epicondyle of humerus |
|---|---|
| Blood supply | Posterior interosseous recurrent artery |
Is anconeus superficial or deep?
Muscles
| Level | Muscle | Innervation |
|---|---|---|
| superficial | extensor carpi radialis brevis | radial nerve (deep branch) |
| superficial | extensor carpi ulnaris | radial nerve (as posterior interosseous nerve) |
| superficial | anconeus | radial nerve |
| intermediate | extensor digitorum | radial nerve (as posterior interosseous nerve) |
Is anconeus and extensor?
It is innervated through a branch derived from the radial nerve that travels beside the medial collateral artery to the muscle. The anconeus muscle functions as an accessory extensor beside the triceps brachii and possibly contributes to posterolateral elbow stability during forearm rotation.
What is anconeus triangle?
Anconeus triangle boundaries are the radial head, lateral epicondyle, and tip of the olecranon. Anconeus triangle is the site for elbow joint aspiration, injection and direct lateral portal for elbow arthroscopy.
How do you release an anconeus?
Is anconeus a synergist?
Its origin is on the lateral epicondyle of the humerus, and its insertion is on the lateral aspect of the olecranon process and posterior ulna. The anconeus abducts the ulna during forearm pronation and it acts as a synergist of the triceps brachii during elbow extension.
Where is Olecranal?
The olecranon is the tip of the elbow and is part of the ulna. (Right) The major nerves and ligaments are highlighted.
What does the anconeus look like?
What is the arcade of Frohse?
The arcade of Frohse (pronounced \ˈfʁoːzə \) is also known as the supinator arch. The arcade is formed by a fibrous band between the two heads of the supinator muscle. The deep branch of the radial nerve passes beneath the arcade accompanied by vessels known as the leash of Henry.
Is supinator deep to Brachioradialis?
Supinator is a spiral muscle contained in the posterior compartment of the forearm, along with brachioradialis, and the superficial and deep forearm extensors. Supinator muscle curls around the proximal part of radius, connecting it with the ulna.
Where is recurrent interosseous artery?
forearm The interosseous recurrent artery is a branch of the posterior interosseous artery just after its origin, within the proximal aspect of the posterior compartment of the forearm.
What artery is in your wrist?
The radial artery runs from the elbow to the wrist along the underside of the arm. Along with the ulnar artery, it delivers blood to the hand. When you take your pulse by pressing two fingers along your wrist just below the thumb, you are feeling the steady pumping of blood through the radial artery.
What is Forarm?
Introduction. The forearm of the upper extremity runs from the elbow to the wrist. Two bones, the radius laterally and the ulna medially, form the forearm. It has two compartments, the anterior (flexor) and posterior (extensor). The two compartments together have twenty muscles.
What’s the main artery called?
aorta The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
Why does my Brachioradialis hurt?
What causes brachioradialis pain? The most common cause of brachioradialis pain is overexertion. If you overload your brachioradialis muscle for extended periods of time, it will become tender and, eventually, painful.
How do you massage the anconeus muscle?
Pressure Motion Technique Move your finger inward one to two centimeters. Tighten your arm muscles and slightly straighten your elbow. You should feel a small divot in your arm, that is where your anconeus muscle lays. Press your finger into the muscle to massage it.
What is olecranon process?
Definitions of olecranon process. process of the ulna that forms the outer bump of the elbow and fits into the fossa of the humerus when the arm is extended. synonyms: olecranon. type of: appendage, outgrowth, process. a natural prolongation or projection from a part of an organism either animal or plant.
Is anconeus muscle of arm?
The anconeus muscle is a small muscle in the posterior compartment of the arm at the lateral aspect of the elbow. It has little functional significance but should be differentiated from the variably present anconeus epitrochlearis at the medial aspect of the elbow.
What is the pronator quadratus?
Pronator quadratus is a square-shaped muscle on the distal forearm that acts to pronate (turn so the palm faces downwards) the hand.
What does anconeus mean in Latin?

What is the back of the forearm called?
The posterior compartment is located behind the humerus and consists of two muscles: Triceps brachii. This muscle, usually referred to as the triceps, runs along the humerus and allows for the flexion and extension of the forearm.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
