[Pregnancy-related pelvic ring disease and its treatment].

ABSTRACT

Pregnancy-related pelvic ring disease brings great suffering to pregnant women, including the separation of the pubic symphysis and sacroiliac joint pain. Hormonal changes leading to ligamentous laxity is the main reason for Pregnancy-related pelvic ring disease. In normal pregnant cases, and the physiologic widening at the symphysis is about 3-7 mm. When the widening of the symphysis is more than 10 mm, it may lead to symptoms and need active treatment. Currently the diagnosis of the pubic symphysis separation is based on the clinical symptoms and signs. The treatment of acute pubic symphysis separation bases on conservative therapy, includes bed rest and physical therapy. But when the widening of the symphysis is more than 4 cm, the surgery intervention may be a good treatment. If the conservative treatment is not obviously effective, the surgery consists of plate fixation in the pubic symphysis and sacroiliac screw fixation. Other indications for the surgical intervention include inadequate reduction, recurrent diastasis, intractable symptoms, and open rupture.
