Question

What are the landmarks for fascia iliaca block?

1) Femoral nerve
2) Lateral femoral cutaneous nerve
3) Obturator nerve
4) Ilioinguinal nerve

Answer 1

A fascia iliaca block targets the femoral nerve, lateral femoral cutaneous nerve, and obturator nerve for anesthesia of the anterior thigh; it does not typically involve the ilioinguinal nerve.

Step-by-step explanation:

The landmarks for a fascia iliaca block, which targets the nerves supplying the anterior thigh and sometimes the medial aspect of the leg, include the femoral nerve, lateral femoral cutaneous nerve, and obturator nerve. The iliopsoas compartment, situated posterior to the inguinal ligament, is the area where the block is usually performed. During the block, these nerves are targeted as they pass under the fascia iliaca, which stretches from the iliac crest to the inguinal ligament. It does not typically involve the ilioinguinal nerve, which is targeted with an ilioinguinal nerve block.
