What is anconeus Epitrochlearis?

The anconeus epitrochlearis muscle is an accessory muscle of the upper limb at the medial aspect of the elbow. It is also known as the accessory anconeus muscle or epitrochleoanconeus muscle and should not be confused with the anconeus muscle which is present at the lateral aspect of the elbow.

Is anconeus a muscle of the arm or forearm?

The anconeus is a small muscle located at the elbow. Attaching to the humerus and ulna, Although the anconeus muscle is active during elbow extension the importance of the anconeus for the movement itself is probably very small.

How do you treat anconeus pain?

Treat strains to the anconeus, or tennis elbow, by protecting it from further injury, rest it, ice it, compress it with an elastic bandage and elevate it. Pain can be treated with non-steroidal anti-inflammatory drugs. Surgery should be considered in very rare cases.

Is anconeus anterior or posterior?

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.

How common is anconeus Epitrochlearis?

The anconeus epitrochlearis muscle is a common anatomic variation, with a prevalence of up to 34%, but the clinical diagnosis of ulnar neuropathy of the elbow as a result of this variation is rare, with an unknown prevalence.

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 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.

Why does my anconeus muscle hurt?

Stretch or impact injuries to the anconeus muscle sustained while playing tennis or with overuse such as excessive handshaking and digging have been implicated in the evolution of anconeus syndrome. In addition, repeated microtrauma may result in the development of myofascial pain in the anconeus muscle.

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.

Is ulnar nerve entrapment rare?

Ulnar nerve entrapment is the second most common compressive neuropathy after carpal tunnel syndrome. The accessory anconeus epitrochlearis muscle – present in 4% to 34% of the general population – is a known, but rare cause of ulnar nerve entrapment at the elbow.

What is bicep brachii?

The biceps brachii (commonly know as the biceps) locates in the anterior compartment of the arm. The biceps consists of two heads, the long and the short head, which they arise proximally and joint to attach to the radius as biceps tendon.

What kind of pain does anconeus epitrochlearis cause?

Anconeus epitrochlearis is caused by entrapment and compression of the ulnar nerve at the elbow by an accessory anconeus muscle (Figure 38-1 ). This entrapment neuropathy manifests as pain and associated paresthesias in the lateral forearm that radiates to the wrist and ring and little fingers in a manner analogous to tardy ulnar palsy.

What should I do if I have anconeus epitrochlearis?

This is done by the use of nonsteroidal antiinflammatories like Tylenol or Advil and COX-2 inhibitors. This along with physical therapy is the route to go for treatment of Anconeus Epitrochlearis. A heating pad can also be used at the area of the elbow and forearm as it is very beneficial in calming down the muscles and relieving pain.

What kind of pain does the anconeus muscle cause?

This entrapment neuropathy manifests as pain and associated paresthesias in the lateral forearm that radiates to the wrist and ring and little fingers in a manner analogous to tardy ulnar palsy. The symptoms often are aggravated by prolonged flexion of the elbow.

Where is the anconeus muscle located in the elbow?

The anconeus muscle lies in the dorsal posterolateral aspect of the elbow measuring 8 × 4 cm in size. Arises from the lateral epicondyle of the humerus and inserts into the lateral aspect of the olecranon and proximal posterior ulna.
