Fascial Fascia Iliae Block - Anatomical Atlas

The iliac fascia originates from the upper and outer sides of the iliac crest, ends at the boundary of the lesser pelvis, fuses medially with the psoas fascia, and extends downward to the level of the lesser trochanter, covering the surface of the iliopsoas muscle
.

At the level of the lateral 1/3 of the inguinal ligament, the iliac fascia is reinforced by the aponeurosis of the transversus abdominis and internal oblique muscle to form a common aponeurosis; at the level of the middle 1/3 of the inguinal ligament, the iliac fascia fuses medially with the pubic fascia , fused laterally with the fascicular aponeurosis surrounding the rectus femoris muscle; at the level of the medial 1/3 of the inguinal ligament, the femoral nerve passes through the fascia iliacus reinforced by the joint aponeurosis, forming the inferior orifice iliac tendon of the fascia iliacus space The intermembranous space is a potential fatty space between the fascia iliacus and the iliopsoas epicardium, in the shape of a triangle, with the fascia iliacus anteriorly and the iliac pelvis posteriorly, connected laterally with the sartorius fascia in the inguinal area, and medially with the pubic bone Muscles are connected; it communicates with the anteromedial extraperitoneal space upward at about the level of L5, and communicates with the subfascia lata fat space through the FN outlet, and communicates with the paravertebral space posteriorly
