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.application/pdfeng© 2023 Vierstraete, Pereira Rodriguez, Renard and Muysoms.
