 The tendon of the psoas minor attaches distally to the pelvis, proximal to the pectineal line, just medial to the iliopubic eminence. This tendon also forms the structural backbone of an extensive aponeurotic envelope, often referred to as iliac fascia. The primary purpose of this video is to show, through a cadaver dissection, how this aponeurotic envelope, when under tension governed by the psoas minor, helps stabilize the position of the underlining iliopsoas. This is the right hip region. There's the right anterior superior iliac spine. The right pubic tubercle. The inguinal ligament has been removed, and we have exposure to the pelvic abdominal cavity. Let's note the large psoas major. The iliac is just lateral to it. The lateral border of the quadratus lumborum. On top of the psoas major is the psoas minor, and we can follow its attachment, its tendinous attachment, into the iliac fascia as well as into bone. So this iliac fascia attaches laterally near the anterior superior iliac spine, is continuous distally into the fascialata of the proximal thigh, and then is continuous on the medial side with the aponeurosis over the obtrater internus. Note this wrong central tendon that actually bifurcates. Some of the tendon goes medial into bone, into the pelvis, and there's a lateral band that continues on as the backbone to this aponeurosis, or the so-called iliac fascia. If I were to simulate a contraction of the psoas minor, tension can be developed and transferred through the aponeurosis, not only medially over to the obtrater internus, but directly over the iliosoas, and that tension then continues into the thigh via the fascialata. The psoas minor can control tension on the iliac fascia, which may control the position of the psoas major, prevent it from bow stringing during flexion. The psoas minor can also control some tension in the more proximal region of the fascialata.
