Anatomical terms of bone

The pubic tubercle is a prominent tubercle on the superior ramus of the pubis bone of the pelvis.

Contents

Structure

The pubic tubercle is a prominent forward-projecting tubercle on the upper border of the medial portion of the superior ramus of the pubis bone. The inguinal ligament attaches to it. [1] Part of the abdominal external oblique muscle inserts onto it. [1] The inferior epigastric artery passes between the pubic tubercle and the anterior superior iliac spine. [2] The pubic spine is a rough ridge that extends from the pubic tubercle to the upper border of the pubic symphysis.

Clinical significance

The pubic tubercle may be palpated. [3] It serves as a landmark for local anaesthetic of the genital branch of the genitofemoral nerve, which lies slightly lateral to the pubic tubercle. [3] This may also be used for the obturator nerve. [4]

Hernias

The pubic tubercle is a useful landmark for identifying hernias. [5] An inguinal hernia will lie anteromedial to the pubic tubercle. [5] A femoral hernia will lie inferolateral to the pubic tubercle. [5]
