Anconeus epitrochlearis muscle resulting in cubital nerve compressive neuropathy: Two case reports.

Background: The anconeus epitrochlearis muscle is an anatomical variant prevalent in amphibians but unusual in humans. In favorable cases, this muscle provides protection to the cubital nerve but can result in neuropathy due to compression of the cubital nerve.

Case Description: We present two cases with different clinical manifestations but both did not respond to conservative treatment.
