Pectineal line

Pectineal Line is a prominent anatomical feature found in the human pelvis. It is a ridge or line on the superior ramus of the pubic bone and is part of the pelvic brim. The pectineal line is significant in the study of anatomy and medicine, as it serves as a landmark for various muscles and ligaments.

Anatomy[edit | edit source]

The pectineal line begins at the pubic tubercle and extends along the superior ramus of the pubic bone. It merges with the iliopectineal line on the ilium, forming part of the pelvic brim. The pectineal line is a significant anatomical landmark as it marks the boundary between the greater and lesser pelvis.

Clinical Significance[edit | edit source]

The pectineal line is a crucial landmark in surgical procedures involving the pelvis. It is particularly important in hip replacement surgeries and procedures to repair pelvic fractures. The pectineal line also serves as a point of attachment for several muscles and ligaments, including the pectineus muscle and the lacunar ligament.

Related Structures[edit | edit source]

Several structures are related to the pectineal line. These include:

Pectineus muscle: This is a flat, quadrangular muscle situated at the anterior part of the upper and medial aspect of the thigh. The pectineus muscle is attached to the pectineal line.
Lacunar ligament: This is a ligament in the inguinal region that connects the inguinal ligament to the pectineal line of the pubic bone.
Cooper's ligament: Also known as the pectineal ligament, this is a strong fibrous band in the pelvis. It extends from the pectineal line to the iliopubic eminence.
