2-26. SHIRODKAR OPERATION (POSTCONCEPTIONAL)
a. General. This operation involves the placement of a collar-type ligature or
other material at the level of the internal os to close it. It is made necessary by
incompetence of the cervix, a condition characterized by habitual midtrimester
spontaneous abortions. The operation is designed to prevent the cervical dilatation that
results in release of uterine contents.
