The nerve to anconeus typically arises from the radial nerve in the spiral groove or just distal to it, entering the anconeus on its deep surface. Its proximal origin means it may be preserved or affected in spiral groove radial nerve palsy depending on the exact lesion level.
EMG of the anconeus is used to localise radial nerve injuries — preserved anconeus function with absent brachioradialis indicates a very distal lesion, while loss of anconeus with preserved triceps confirms spiral groove localization. The anconeus nerve origin at the spiral groove level makes it one of the key landmarks in radial nerve injury mapping.
EMG of the anconeus nerve territory distinguishes spiral groove from more distal radial nerve injury — preserved anconeus with absent brachioradialis is rare and suggests a very distal posterior interosseous lesion.
