Clinical Media Index

The video demonstrates how to perform an adductor canal block using a high-frequency linear ultrasound transducer with a nerve exam setting. The patient is positioned supine with their leg slightly externally rotated, and the transducer is placed medially at the mid-thigh in a transverse orientation. Key anatomical structures, including the femur, femoral artery, and vein, and surrounding muscles (sartorius, vastus medialis, and adductor longus), are identified. The saphenous nerve, appearing as a small, round hyperechoic structure, is targeted, or if not visible, injections are directed lateral to the femoral artery below the sartorius. The needle is inserted in-plane from lateral to medial, and once positioned, local anaesthetic is injected, creating a hypoechoic spread around the femoral artery to achieve effective anaesthesia. This technique can help you achieve successful pain management for the thigh region.
