Linea pecten ossis pubis

Linea pecten ossis pubis

The linea pecten ossis pubis is a bony ridge located on the superior pubic ramus, which is part of the pelvis. It is also known as the pectineal line or the pecten pubis. This anatomical feature plays an important role in the attachment of various muscles and ligaments in the pelvic region.

Anatomy

The linea pecten ossis pubis is a prominent ridge that runs along the superior aspect of the pubic ramus. It extends from the pubic tubercle to the pectineal line of the pubic bone. The ridge is sharp and serves as the attachment site for several muscles and ligaments.

Function

The primary function of the linea pecten ossis pubis is to provide attachment points for muscles and ligaments involved in the stabilization and movement of the pelvis. Some of the important structures that attach to this ridge include:

• Pectineus muscle: This muscle originates from the pectineal line and plays a role in hip flexion and adduction.
• Inguinal ligament: The inguinal ligament attaches to the pubic tubercle, which is located at the medial end of the linea pecten ossis pubis. It forms the lower border of the inguinal canal.
• Cooper's ligament: Also known as the inguinal ligament's lacunar ligament, it attaches to the pectineal line and provides support to the inguinal canal.

Clinical Significance

The linea pecten ossis pubis is an important landmark in surgical procedures involving the pelvis. Surgeons often use this ridge as a reference point for various procedures, such as hernia repairs and pelvic reconstructions.
