Structural inability of the cervical os to remain closed and support a growing fetus. This problem has commonly been associated with recurrent spontaneous second-trimester abortions. A higher incidence of this structural abnormality is noted after cervical trauma, e.g., previous vaginal or cesarean births, cervical laceration, conization of the cervix. It also has been reported among daughters whose mothers were treated with diethylstilbestrol (DES) during their pregnancies. Traditionally, cerclage has been used for treatment even though controlled trials of its effectiveness have not been uniformly successful.See: cerclage; Shirodkar operation

cervical incompetenceThe inability of the inner opening of the neck of the womb to remain properly closed. This is a cause of repeated, painless, spontaneous abortions around the fourth or fifth month of pregnancy and affects about one pregnancy in 100. This can be prevented with a temporary encircling stitch (a Shirodkar suture), but the difficulty is to know which women are likely to be affected. Women with a history of mid-term miscarriage are obvious candidates for cerclage. The procedure can be done as an emergency if threatened miscarriage is detected in time.
