The anconeus muscle is a small muscle in the posterior compartment of the arm at the lateral aspect of the elbow. Its functional significance is not well understood 5.
It should not be confused with the anconeus epitrochlearis, an accessory muscle that is present in up to one third of people, and may be implicated in some cases of cubital tunnel syndrome 4.
Summary
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
Related pathology
In chronic cases of lateral epicondylitis (tennis elbow) increased signal intensity of the nearby anconeus muscle may be an associated finding.
