Abstract: The sacrotuberal ligament was studied in seven Kars dogs. It was observed that Lig. sacrotuberale that started in the last sacral vertebra and first two coccygeal vertebrae and clinged to the lateral angle of the Tuber ischiadicum was a flat structure, yet it was in the shape of a strong round fibrous cord after 28 mm onward. It was also determined that Lig. sacrotuberale served as an origin for m gluteus superficialis, cranial part of M. biceps femoris, M. priformis and M. abductor cruris caudalis.
