AJOG Expert Review: Pelvic floor injury during va**nal birth is life-altering and preventable: what can we do about it? Interactions among levator, anterior wall, and apical ligaments
The red arrows represent the force created by gravity and abdominal pressure. With normal levator function (red band) (A), the hiatus is closed, and the va**nal walls are in apposition; the anterior and posterior pressures are equal and cancel (blue arrows). Levator damage (B) results in hiatal opening, and the va**na becomes exposed to a pressure differential between abdominal and atmospheric pressures. This pressure differential (C) makes the va**nal wall protrude and creates a traction force on the cardinal ligament and uterosacral ligament. https://ow.ly/t8PG50QQYL6
