Extensor digiti minimi

Dr Henry Knipe and Greg Mirt et al.

Extensor digiti minimi (EDM) 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 an extensor retinaculum near the wrist and passes through the 5th extensor compartment of the wrist.
