2016, American Journal of Obstetrics and GynecologyCitation Excerpt :A short cervix is associated closely with subsequent spontaneous PTB2 and a reliable sign of its latency. The lack of success of a digital examination in the prediction of PTB because of its subjectivity, high interobserver variability,18 inaccuracy for evaluation of the internal os,19 and nonspecificity20 makes TVU CL far superior to manual examination of the cervix in PTB prediction. It is the internal os, which is visible only on ultrasound scanning, that first starts to open, and not the external os, which is the only cervical portion that is palpable by digital examination.

2011, Obstetrics and Gynecology Clinics of North AmericaCitation Excerpt :However, this method is a poor predictor of preterm delivery, because is not reliable, is subjective, and has greater than 50% interobserver variability.6 Manual cervical examination is also nonspecific, as 15% to 16% of primiparous women and 17% to 35% of multiparous women who are delivered at term have had a cervical dilation between 1 and 2 cm in the late second trimester.7 In the last 3 decades, measurement of CL using TVU has become an accurate screening tool for preterm delivery.
