For more information of "Extensor Digitorum Communis", see the section below.
Functions
- Extends the fingers at the knuckles
- Assists in wrist extension
- Stabilizes the wrist joint
Anatomy
- Origin: Lateral epicondyle of the humerus
- Insertion: Extensor tendon of each finger

Clinical Significance
Tendonitis: Overuse of the EDC muscle can lead to inflammation of its tendon, causing pain, swelling, and stiffness.
Rupture: Trauma or chronic overuse can cause a rupture of the EDC tendon, resulting in loss of finger extension.
Examination
- Finger Extension Test: The patient extends their fingers against resistance, isolating the EDC muscle.
- Wrist Extension Test: The patient extends their wrist against resistance, testing the strength of the EDC and other wrist extensors.
Treatment
- Tendonitis: Rest, ice, compression, and elevation (RICE); physical therapy
