The fascia iliaca block is a regional anesthetic technique used in procedural medicine, particularly relevant to pain management and orthopedic ultrasound. This nerve block targets the femoral, lateral femoral cutaneous, and obturator nerves by injecting local anesthetic into the potential space beneath the fascia iliaca, superior to the iliacus muscle. Ultrasound guidance is increasingly utilized for this procedure, enhancing precision and minimizing complications.
Ultrasound allows for real-time visualization of the needle tip, local anesthetic spread, and surrounding anatomical structures like blood vessels, ensuring accurate placement and increasing the block’s success rate. It is commonly performed for femur fractures, hip surgeries, and other lower extremity procedures, offering effective analgesia and reducing the need for systemic opioids, making it a valuable tool in modern medical and ultrasound-guided procedural practice.
