    Study Notes

    Landmarks of the Pelvis

    • Nine key landmarks are identified on the pelvis.
    • These include the sacral promontory, ala or wings of the sacrum, sacroiliac joint, iliopectineal line, iliopubic eminence, pectineal line, pubic tubercle, pubic crest, and symphysis pubis.

    Pelvic Ligaments

    • Various ligaments support and stabilize the pelvic structures.
    • These include the sacrotuberous ligament, anterior longitudinal ligament, iliolumbar ligament, anterior sacroiliac ligament, inguinal ligament, and sacrospinous ligament.

    Types of Pelvis

    • Four common types of female pelvis are identified based on shape.
    • These are gynecoid, android, anthropoid, and platypelloid.
    • Gynecoid is the most common type, favorable for vaginal birth.

    Diameters of Pelvis

    • Measurements of the pelvic diameters are crucial for evaluating the possibility of vaginal delivery.
    • These include the true/anatomical conjugate (11 cm), obstetric conjugate (10cm), diagonal conjugate (12 cm) , right oblique diameter (12cm), left oblique diameter (13cm), transverse diameter (12cm), and anteroposterior diameters (12cm) .
