Abnormal weakness of the cervix that can result in recurrent miscarriages. An incompetent cervix may gradually widen under the weight of the fetus from about the 12th week of pregnancy onwards, or may suddenly open during the second trimester. The condition is detected by an internal examination or by ultrasound scanning. Treatment is with a suture (stitch) applied like a purse string around the cervix during the 4th month of pregnancy. The suture is left in position until the pregnancy is at or near full term and is then cut to allow the mother to deliver the baby normally.
