Iliopubic eminence

Iliopubic eminence is a part of the pelvis that is located on the superior ramus of the pubis. It is a bony prominence that is important in the attachment of several muscles and ligaments. The term "iliopubic" is derived from the Latin words "ilium", meaning "flank", and "pubis", meaning "pubic bone". The "eminence" refers to a projection or prominence.

Anatomy

The iliopubic eminence is located on the superior ramus of the pubis, which is part of the pelvic girdle. It is situated between the pubic tubercle and the iliopectineal line. The eminence serves as the point of attachment for the iliofemoral ligament and the pectineus muscle.

Function

The iliopubic eminence plays a crucial role in the stability of the pelvic girdle and the movement of the lower limbs. The iliofemoral ligament, which attaches to the eminence, is one of the strongest ligaments in the human body and helps to prevent hyperextension of the hip joint. The pectineus muscle, also attached to the eminence, is involved in the adduction and flexion of the thigh at the hip joint.

Clinical significance

Due to its location and the structures attached to it, the iliopubic eminence can be involved in several medical conditions. For instance, fractures of the pubic ramus can involve the iliopubic eminence and can lead to pain and difficulty in walking. In addition, inflammation or injury to the iliofemoral ligament or the pectineus muscle can also affect the iliopubic eminence.
