Anconeus muscle

Dr Mohamed Saber and Dr Henry Knipe et al.

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.

In chronic cases of lateral epicondylitis (tennis elbow) increased signal intensity of the nearby anconeus muscle may be an associated finding.
