In this short video we review the anatomy and approach to a fascia iliaca compartment block, which aims to block the femoral nerve, obturator nerve, and lateral femoral cutaneous nerve (also called a 3 in 1 block). This is a great block for patients with fractures of the femoral neck, intertrochanteric fractures, or proximal femur fractures. Pain is better controlled with nerve blocks and less opiates are required when this approach is used for hip fractures. This can be done with ultrasound guidance, or with a blind technique. Once the needle is through the fascia lata and fascia iliaca, the anesthetic is injected to dissect the iliacus muscle off the fascia iliaca, and the anesthetic tracks proximally up the fascial plane to anesthetize all 3 nerves (at least in theory!).
