 Therefore, inferior to the arcuate line, the rectus abdominis rests directly on the transversalis fascia.If one dissects the anterolateral abdominal wall, the arcuate line may be difficult to see, since all the aponeuroses are translucent.The arcuate line must be incised at its lateral-most point in order to enter the space of Retzius and space of Bogros from within the rectus sheath to carry out the caudal portion of dissection during retrorectus repair and transversus abdominis release.
