The common extensor tendon is a tendon that attaches to the lateral epicondyle of the humerus.
The common extensor tendon serves as the upper attachment (in part) for the superficial muscles that are located on the posterior aspect of the forearm:
- Extensor carpi radialis brevis
- Extensor digitorum
- Extensor digiti minimi
- Extensor carpi ulnaris[1][2]
The tendon of extensor carpi radialis brevis is usually the most major tendon to which the other tendons merge.[2]
Function
The common extensor tendon is the major attachment point for extensor muscles of the forearm. This enables finger extension and aids in forearm supination.
