The inguinal ligament is a band of tissue that extends from the anterior superior iliac spine (ASIS) to the pubic tubercle and is an important anatomical landmark for clinicians and surgeons. Although there are no commonly used synonyms for the inguinal ligament, it can sometimes be referred to as the Poupart's ligament or the lacunar ligament. In addition, the term "groin ligament" may also be used to describe the inguinal ligament. It is important to note that the inguinal ligament plays a crucial role in the formation of the inguinal canal and is involved in various medical conditions such as hernias, so understanding its function and location is essential.
