• Origin

Lateral epicondyle of the humerus.

• Insertion

Lateral surface of the olecranon process of the ulna.
Proximal posterior surface of the ulna.

• Agonist(s)

Triceps brachii (assists in elbow extension).

Brachialis (synergist in elbow flexion, especially when the forearm is pronated).

• Antagonist(s)

- Biceps brachii,

- Brachioradialis,

- Pronator teres (for pronation of the forearm).

• Function

Assists in elbow extension.
Stabilizes the elbow joint during forearm pronation and supination.
Helps in the final extension of the elbow when the triceps is fatigued.

TRIGGER POINT(S)

• Location

Trigger points in the anconeus muscle are often found along the muscle belly near the lateral epicondyle and distal ulna.

They are usually located at the posterior aspect of the elbow, close to the olecranon process.

• Pain Referral Pattern

Pain is typically felt around the elbow joint, particularly on the lateral aspect.

Referral pain may radiate into the forearm, extending down to the wrist or even the proximal forearm, mimicking symptoms of lateral epicondylitis (tennis elbow).

💢

Potential Causes

• Repetitive elbow extension, especially during activities requiring heavy lifting or overhead movements.

• Overuse of the elbow joint during sports or manual labor (e.g., tennis, throwing, weightlifting).

• Muscle imbalances around the elbow joint (e.g., weakness in the triceps or brachialis).

• Inadequate rest or overloading of the elbow joint during repetitive motions.

✅

Prevention Tips

• Avoid excessive strain on the elbow by practicing proper lifting techniques and form.

• Regularly stretch and strengthen muscles around the elbow joint, especially the triceps and forearm extensors.

• Incorporate rest periods during activities that involve repetitive elbow movements.

• Pay attention to ergonomics when performing manual labor or sports.

• Perform warm-ups before engaging in activities that involve repetitive arm motions.
