ABSTRACT Routine dissection of a 69-year-old American Caucasian female revealed a unique accessory slip of the deltoid muscle which was conjoined with the proximal portion of teres minor. The variant muscle bundle was united with the distal portion of the deltoid, but deviated superomedially and fused with the origin of teres minor. This discovery possesses clinical relevance with respect to surgical repair of shoulder pathology or trauma. Shoulder injuries and their respective repairs are very common. Therefore, consideration of this variant is necessary for the correct diagnosis and treatment of massive trauma or other shoulder pathology that is refractory to standard treatments.
