Anconeus muscle is a small skeletal muscle located on the posterior aspect of the elbow joint. It has a close structural and functional relationship with the triceps brachii muscle. Due to its anatomical position, it is associated with both the posterior compartment of the arm and the posterior compartment of the forearm. Although its clinical significance is limited, it may become relevant in certain traumatic injuries and neurological impairments. Its Latin name, musculus anconeus, is derived
