Fig. 3. Anatomy (A) and ultrasound image (B) of the femoral nerve (FN). The FN is found lateral to the common femoral artery (CFA) (B-left). The nerve is smaller than the CFA and the artery is smaller than the adjacent common femoral vein (CFV). Compression with the transducer occludes the CFV leaving the FN and CFA (B-right). Femoral nerve block is administered with ultrasound guidance, which is easy to perform and has a low risk of complications.
