Iliacus block

CHAPTER 28 Iliacus block

Clinical anatomy

The iliacus fascia covers the iliacus and psoas muscles in the pelvis and descends into the thigh with these muscles (Fig. 28.1). The femoral nerve lies anterior to the psoas muscle initially, with the lateral cutaneous nerve of the thigh lateral to the psoas muscle and obturator nerve medial. At the inguinal ligament, the femoral nerve lies in a gutter between the psoas and iliacus muscles. These nerves thus lie beneath the iliacus fascia (Fig. 28.1). Spread of local anesthetic (Figs 28.2 and 28.3) beneath the iliacus fascia produces a higher success rate of anesthesia of the femoral nerve, lateral cutaneous nerve of the thigh, and obturator nerves than the femoral nerve block technique.
