Interfoveolar ligament

The interfoveolar ligament (ligament of Hesselbach) is a fibrous band that forms the functional medial border of the deep inguinal ring. The interfoveolar ligament runs from the inferior and posterior aspect of transversus abdominis muscle to insert into the inguinal ligament anterior to the transversalis fascia.

• Arches down from lower border of transversus around the vas to the inguinal ligament
• Constitutes the functional medial edge of the deep ring
  • Posterior wall in medial part
    • Conjoint tendon reinforces posterior aspect of superficial inguinal ring
