Round ligament

Round Ligament

The Round Ligament (also known as the ligamentum teres uteri) is a key anatomical structure in the female reproductive system. It is a fibromuscular cord that connects the uterus to the labia majora.

Anatomy

The Round Ligament originates at the uterine horns, in the region of the fallopian tubes. From there, it extends through the inguinal canal and terminates at the labia majora. The ligament is approximately 10-12 cm in length and is composed of smooth muscle fibers, collagen, and elastin.

Function

The primary function of the Round Ligament is to maintain the position of the uterus within the pelvis. It achieves this by acting as a tether, preventing the uterus from moving too far posteriorly or anteriorly. During pregnancy, the ligament elongates and thickens to accommodate the growing uterus and helps to keep it in a central position.

Clinical Significance

The Round Ligament can be a source of pain during pregnancy, a condition known as Round Ligament Pain. This is typically caused by the rapid growth of the uterus, which can stretch and strain the ligament.

In addition, the ligament can be involved in certain gynecological surgeries. For example, during a hysterectomy, the ligament is often cut to allow removal of the uterus.
