Last revised by Henry Knipe on 11 Aug 2021

Extensor digiti minimi (EDM) muscle (also known as extensor digiti quinti proprius) is a muscle of the superficial layer of the posterior compartment of the forearm, and with other extensor muscles arises from a common extensor tendon attached to the lateral epicondyle of the humerus. The EDM represents a medial group of superficial extensor muscles. The EDM passes under the extensor retinaculum near the wrist and passes through the 5th extensor compartment of the wrist. It is one of the extrinsic muscles of the hand.
