In the Nyhus classification of groin hernias, which type describes a large direct hernia with disruption of the posterior inguinal wall?

• A Type IIIA ✓
• B Type IIA
• C Type IIB
• D Type IIIB

Explanation

Nyhus Type IIIA describes a direct hernia with posterior wall defect (transversalis fascia defect). Type IIIB is a large indirect hernia with posterior wall involvement or a pantaloon hernia. Type IIA is a small indirect hernia with normal internal ring; Type IIB is a larger indirect hernia with dilated ring but intact posterior wall. Nyhus classification is surgically relevant because Types III and IV require posterior wall repair (preperitoneal or mesh-based techniques) rather than simple high ligation.
