Anatomical terms of bone

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

Structure

[edit]

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

[edit]

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

[edit]

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]
