Abstract
It has been reported that via its attachment to the sacrotuberous ligament, the long head of the biceps femoris muscle is capable of influencing the motion or stability of the sacroiliac joint. However explanations of this mechanism focus primarily on these two structures and do not address the potential influence of surrounding tissues. A review of the anatomical literature was therefore undertaken to determine what muscles and ligaments are commonly associated with the sacrotuberous ligament. The morphology of this ligament in situ is presented and discussed so that readers may appreciate the clinical anatomy of this structure.
