ABSTRACT
DEFINITION OF CERVICAL INSUFFICIENCY (CI) e concept of the cervix being “so slack that it cannot rightly … keep in the seed” was rst hypothesized in the 1658 text Practice of Physick by Rivière et al.1 In the 1940s and 1950s, the term “cervical incompetence” came into vogue, and surgical interventions were described to treat the “weak” cervix. Only recently have properly controlled scientic studies on the subject been performed.
