The superior gemellus muscle (SGM) normally arises from the outer surface of the spine of the ischium, blends with the upper part of the tendon of the obturator internus, and is inserted with it into the medial surface of the greater trochanter. In this paper, we describe an anatomical variation in which the SGM is absent bilaterally. Therefore, as there are not many cases in literature, our attention has been drawn to the importance about absence of SGM, in order to improve anatomical and clinical knowledge about this finding.

KEY WORDS: Gross anatomy; Gemellus superior muscle; Anatomical variation.
