The uterosacral ligament, also known as the rectouterine ligament, is a band of tissues that connects the uterus to the sacrum. This ligament is an important structure that supports the uterus and helps maintain its proper position in the pelvic cavity. However, there are several other synonyms for this ligament that are worth mentioning. These include the sacrouterine ligament, the posterior cervical ligament, and the ligamentum rectouterinum. While these terms may not be as commonly used as the uterosacral ligament, they are still important for medical professionals to know and understand in order to accurately diagnose and treat a range of gynecological conditions.
