Recently, vajinal delivery rate with forceps or vacuum decreases despite the increasing rate of cesarean section. The incidence of using instrumental techinques differs in various countries. Inaccurate indications of operative delivery, skipping the evaluation of cephalopelvic disproportion, injury to the mother or baby due to improper use of instruments and over-traction, failure to achieve informed consent, failure of supervision during intervention as necessary may cause legal problems. To day, due to high rates of mortality and morbidity in operative deliveries, vacuum and forceps are only used in low pelvis or in pelvic outlet. Operative delivery must be done by experienced consultants in accurate indications and adequate training is obligatory. Copyright © 2010 by Türkiye Klinikleri.
