The answer is B. Direct inguinal hernia, as it occurs above and medial to the pubic tubercle, specifically protruding through a weakness in the posterior wall of the inguinal canal at Hesselbach's triangle. This type of hernia develops directly through the abdominal wall rather than following the inguinal canal like an indirect hernia. Direct hernias typically occur in older adults due to weakening of the abdominal muscles over time. In contrast, indirect inguinal hernias emerge lateral to the inferior epigastric vessels and follow the path of the spermatic cord through the inguinal canal. Femoral hernias appear below and lateral to the pubic tubercle, passing through the femoral canal. Obturator hernias, as described in 1, 2, 3, 4, 5, occur through the obturator foramen in the pelvis, not near the pubic tubercle. The anatomical relationship to the pubic tubercle is a key diagnostic feature when differentiating between these hernia types during physical examination. Some key points to consider when evaluating hernias include:
- The location of the hernia in relation to the pubic tubercle
- The type of hernia and its typical presentation
- The importance of early diagnosis and treatment to prevent complications and reduce morbidity and mortality, as highlighted in 1 and 4. It's worth noting that while the provided evidence discusses various aspects of obturator hernias, the question specifically asks about the type of hernia located above and medial to the pubic tubercle, which is a direct inguinal hernia.
