EIT Ambivium, Linea Semilunaris, and Fulcrum Abdominalis.

Building upon the recent advancements in posterior component separation techniques for complex abdominal wall hernia repair, highlights the critical importance of a thorough understanding of the abdominal wall anatomy. To address anatomical concepts with a pivotal role in hernia repair, we propose two new terminologies: "EIT Ambivium" referring to the lateral border of the rectus sheath, and "Fulcrum Abdominalis" demarcating the point where the Linea Arcuata intersects with the EIT Ambivium.
