Anatomy · Lower limb

Sample item

A bulge below and lateral to the pubic tubercle is irreducible, and surgery shows the neck passing medial to the femoral vein. Which structure forms the medial boundary of the neck?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Lacunar ligament

The femoral ring is bounded medially by the lacunar ligament, anteriorly by the inguinal ligament, posteriorly by the pectineal ligament and laterally by the femoral vein. The sharp lacunar edge makes strangulation likely.

Option by option

  • A. Inguinal ligament

    The inguinal ligament forms the anterior boundary of the ring.

  • B. Femoral vein

    The femoral vein forms the lateral boundary, not the medial.

  • C. Lacunar ligament (correct)

    Correct. The lacunar ligament is the sharp medial boundary that strangulates the hernia.

  • D. Pectineal ligament

    The pectineal ligament forms the posterior boundary of the ring.
