posterior wall
Last reviewed 08/2021
The posterior wall of the inguinal canal is formed medially from the conjoint tendon and laterally by transversalis fascia and peritoneum. The transversalis fascia is supported by the interfoveolar ligament.
The inferior epigastric artery lies posterior to the posterior wall of the canal at the medial edge of the deep inguinal ring. Its pulsation is used as a landmark in surgery on the canal. The obliterated umbilical artery also lies posterior to the posterior wall but more medial than the inferior epigastric artery.
