An accessory muscle, anconeus epitrochlearis is present in up to one third of people, and may be implicated in some cases of cubital tunnel syndrome 4.
origin: lateral epicondyle of the humerus
insertion: olecranon and proximal quarter of the posterior shaft of the ulna
arterial supply: posterior interosseous recurrent artery
innervation: radial nerve
action: elbow extension (weak) 5
In chronic cases of lateral epicondylitis (tennis elbow) increased signal intensity of the nearby anconeus muscle may be an associated finding.
