Most pelvic closures are for women after normal delivery, and they restore the pubic symphysis to its pre-pregnancy state. It also maintains the stability of the sacroiliac joint and prevents inflammation of the sacroiliac joint in later stages. Since there are many important organs in the pelvis, pelvic closure can maintain the stable anatomy of these organs and prevent the common clinical prolapse of the uterus. After the uterus is closed, it can also significantly improve the abnormalities of urination and defecation caused by the separation of the pubic symphysis, as well as the decrease in the quality of sexual life due to vaginal laxity. Some patients with severe separation of the pubic symphysis may also experience significant pain, limited hip abduction and external rotation, and even inability to bear weight and move the lower extremities, and some patients may be unable to turn over because of the pain. After pelvic closure, the above clinical symptoms can be significantly reduced.
