3d Render of the Border of the Uterus, Surface Anatomy

Description

Centered in the female pelvis, the uterus is presented with attention to its lateral borders (margo lateralis uteri), tracing the contour from the fundus superiorly toward the junction with the cervix inferiorly. Along the superolateral margin, the uterine tubes enter at the uterine cornua, a paired landmark that anchors the broad ligament and frames the fundal contour. Ligamentous insertions align along this border, with the round ligament of the uterus arising anteroinferior to the tube and the utero-ovarian (proper ovarian) ligament attaching posteroinferiorly. Spatial relationships matter here. Focusing on the uterine border is practical for both pelvic examination and operative anatomy because the lateral margin corresponds to the mesometrial attachment and sits in close proximity to the uterine vessels as they course within the base of the broad ligament toward the cervix. During hysterectomy or salpingectomy, orientation at the cornu helps prevent misidentification of the tubal ostium, round ligament, or utero-ovarian ligament when developing windows in the broad ligament and controlling the utero-ovarian or uterine pedicles. This is also the region where adnexal torsion and ectopic pregnancy are localized in relation to the uterine cornua, and where congenital müllerian anomalies can alter the symmetry of the fundal margins. Gynecology and reproductive anatomy courses use this type of surface anatomy rendering to teach uterine orientation, cornual landmarks, and ligament attachments without the distraction of deep pelvic compartments. Publishers can pair it with procedural chapters on laparoscopic hysterectomy, salpingectomy, or cornual ectopic management to clarify where the uterine tube meets the uterine wall and how the lateral uterine margin relates to the broad ligament.
