Anatomy Origin: Superior lateral margin of the ischial tuberosity. Insertion: Quadrate tubercle on the intertrochanteric crest of the femur. Key Relations: Lies between the inferior gemellus and the upper margin of the adductor magnus muscle. Functions Laterally rotates and adducts the thigh at the hip joint. Supply Nerve Supply: Nerve to quadratus femoris (L5, S1).

Anatomy Attaches from just medial to the iliopubic eminence, adjacent bone and obturator membrane. It blends with the joint capsule and the iliofemoral ligament to attach to the femur. Functions Provides static support to the hip joint. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Small prominent forward-projecting bulge on medial part of upper surface of superior ramus of pubis, to which the inguinal ligament is attached. Clinical Pectineal line starts at tubercle. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Midline cartilaginous joint between superior pubic rami (left and right). Clinical In pregnancy, there is hormone-mediated laxity of the symphysis, assisting passage of baby during birth; the joint may disrupt (diastasis) leading to pelvic girdle pain. Ankylosing spondylitis causes bony union. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Large hole/aperture/foramen (round in male, oval in female) formed by pubis and ischium, most of which is closed off by a strong membrane emanating from its borders, leaving a gap – the obturator canal, through which the obturator vessels pass.

Anatomy Origin: Lateral surface of T12 and L1 and the intervening intervertebral disc. Insertion: Pectineal line of pelvic brim and iliopubic eminence and iliac fascia. Key Relations: -Found in only 60% of population. -When present it is found lying across the surface of the psoas major muscle. Functions Weakly flexes the trunk. Supply Nerve Supply:
