Common extensor tendon, and where does it originate?
The common extensor tendon refers to the common origin of the extensor muscles of the forearm including the extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum communis, extensor carpi ulnaris, and extensor digiti minimi muscles. It originates from the lateral epicondyle, which is the bony projection of the lateral aspect of the distal humerus proximal to the capitellum. The anconeus and supinator muscles also originate at the lateral epicondyle.
