entrapment syndromes of the upper limb: a pictorial review. PDFS (a) and PD sequence (b) of 40-year-old male with anconeus denervation oedema (white arrows) due to radial nerve neuropathy. The anconeus is supplied by the radial nerve before it bifurcates into the deep motor and superficial sensory branches, hence the cause of neuropathy in this case will be proximal to the bifurcation

The anconeus muscle is a small muscle in the posterior compartment of the arm at the lateral aspect of the elbow. It has little functional significance but should be differentiated from the variably present anconeus epitrochlearis at the medial aspect of the elbow.
Summary
- origin: lateral epicondyle of the humerus
- insertion: olecranon of the ulna
- arterial supply: posterior interosseous recurrent artery
- innervation: radial nerve
- action: elbow extension (weak)
Related pathology
In chronic cases of lateral epicondylitis (tennis elbow) increased signal intensity of the nearby anconeus muscle may be an associated finding.
