Separation of the paired rectus muscles that form the central abdominal wall is referred to divarication of the rectus abdominis muscles. This is not uncommon after pregnancies and can potentially result in a range of issues including abdominal laxity, herniation of abdominal contents, and back pain because of inadequate core strength.

Whilst the separated rectus muscles can be repaired through a direct incision, such an approach generally results in a readily visible scar. Indirect approaches via incisions with the underwear  line are often possible and result in a more acceptable scar.
