The Dorsoepicondylar Medial Muscle a Clinically Relevant Anatomical Variation

SUMMARY: Anatomical variations in the axillary region do not always appear in modern human anatomy texts, which leaves the risk of diagnostic and surgical errors by doctors unaware of these variations. This work presents an anatomical variation of muscular type in the axillary region that can potent...
