cervical incompetence

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.
