Common extensor tendon
Posterior surface of the forearm. Superficial muscles. (Common extensor tendon not labeled, but region is visible at upper right.)

The common extensor tendon is a tendon shared by a number of extensor muscles in the forearm. It attaches to the lateral epicondyle of the humerus.

It serves as the origin (in part) for a number of muscles, largely in the posterior compartment of the forearm:

  • Extensor carpi radialis brevis
  • Extensor digitorum
  • Extensor digiti minimi
  • Extensor carpi ulnaris
