Figure 2: (a) Image shows the normal course of the femoral nerve emerging from the lateral border of psoas major muscle, running along the groove between the iliacus-psoas major muscle and entering the thigh below the inguinal ligament lateral to the femoral artery. The psoas major muscle has been faded to show the course of femoral nerve running posterior to it. The external iliac artery runs along the medial border of the psoas major muscle. (b) Image shows the intestines overlapping the upper aspect of the psoas muscle. The presence of intestine makes it difficult to trace the femoral nerve beyond the intestinal shadow on US scanning, (Image adapted from Essential Anatomy app version 5.0.5)
