%X background: intrauterine devices (luds) are reversible birth control methods that are widely used throug-hout the world. it is estimated that 120 million women use an iud in the world as a contraceptive. aim: to assess the risk factors that may relate to incorrect insertion of the iud. methods: the sample included 93 patients of a family health center, talca, chile. using contingency tables, various measures of association were calculated, and the cases of incorrectly positioned iud were compared with the cases where one or more risk factors were identified. results: we found an incidence of 15.8% of incorrectly positioned iud, of which 2.1% presented with uterine perforation, 2.1% with embedment of the iud and 11.8% with a descended iud. we identified the following risk factors for incorrectly positioned iud: cesarean section (rr: 2.31), difficulty on insertion (rr: 3.31) and practitioner's opini¨®n of an uncertain result (rr: 3.64), with a sensitivity of 73.3%. conclusions: transvaginal ultrasound is a crucial tool for confirmation of proper insertion of an iud and should be considered a routine examination when any of the identified risk factors are present.
