Pectineal line (pubis)

Pectineal line

The pectineal line of the pubis, also known as the iliopectineal line, is a ridge on the superior ramus of the pubic bone. It is an important anatomical landmark in the pelvis.

Anatomy

The pectineal line extends from the pubic tubercle to the iliopectineal eminence. It serves as the attachment point for the pectineus muscle and the inguinal ligament. The line is continuous with the arcuate line of the ilium, forming part of the pelvic brim.

Function

The pectineal line provides attachment for several structures:

• The pectineus muscle, which is involved in hip flexion and adduction.
• The inguinal ligament, which runs from the pubic tubercle to the anterior superior iliac spine.

Clinical Significance

The pectineal line is a key landmark in various surgical procedures, including hernia repairs and pelvic surgeries. It is also used in the assessment of pelvic fractures.
