Bipartite medial cuneiform: magnetic resonance imaging findings and prevalence of this rare anatomical variant.

Objective: To describe the imaging features of bipartite medial cuneiform and to determine the prevalence of this rare anatomical variant in a large group of patients that were evaluated by magnetic resonance imaging (MRI) of the foot.

Materials And Method: Seven hundred and fifty-one patients that underwent MRI of the foot from May 2016 to December 2018 were included in the study (mean age 49 years; 540 females; 211 males). All MRIs were retrospectively analyzed to identify bipartite medial cuneiform.

[Adequacy of the device intrauterine by ultrasound evaluation: postpartum and post-abortion insertion versus insertion during the menstrual cycle].

Purpose: To compare by transvaginal ultrasound the position of the intrauterine device (IUD) inside the uterine cavity, depending on the time of insertion, postpartum and post-abortion, and during the menstrual cycle.

Methods: Epidemiologic, observational and cross-sectional study carried out between February and July, 2013. A total of 290 women were included, 205 of them with insertion during the menstrual cycle and 85 during the postpartum and post-abortion periods.
