Anatomical structure in the pelvis

Pectineal ligament

The pectineal ligament, also known as the inguinal ligament of Cooper, is a strong fibrous band that is part of the pelvis's anatomy. It is an important structure in the context of inguinal hernia repairs and is often utilized in surgical procedures.

Anatomy

The pectineal ligament is located along the superior ramus of the pubis and is an extension of the lacunar ligament. It runs along the pectineal line of the pubis, which is a ridge on the superior ramus of the pubic bone. The ligament is composed of dense connective tissue and provides support to the inguinal canal.

Function

The primary function of the pectineal ligament is to provide structural support to the pelvic region. It serves as an attachment point for the transversalis fascia and the conjoint tendon, which are important structures in the formation of the posterior wall of the inguinal canal. This ligament plays a crucial role in maintaining the integrity of the inguinal region, especially during increased intra-abdominal pressure.

Clinical significance

The pectineal ligament is of particular interest in the surgical repair of inguinal hernias. It is often used as a point of fixation for mesh in Lichtenstein tension-free hernioplasty and other hernia repair techniques. The ligament's robust nature makes it an ideal anchor point for surgical interventions aimed at reinforcing the inguinal canal.
