A closed submucous cervical suture for the incompetent cervix.

Twenty-five consecutive cases of cervical incompetence were treated by a closed submucous cervical suture that I developed. Twenty patients proceeded to term and delivered live babies. This was statistically significant when compared to their own reproductive performance before operation (P less than 0.001). The suture described is simple, easy, quick, bloodless, anchored to three points in the cervical musculature and is passed deep to the cervical blood vessels.
