[Ultrasound-guided obturator nerve block].
We reviewed the technique and anatomy for the ultrasound-guided obturator nerve block, especially interadductor approach. Although it is sometimes difficult to observe obturator nerve in the ultrasound image, obturator nerve block is completed observing three muscle layers, adductor longus muscle, adductor blevis muscle and adductor magnus muscle, in the ultrasound image. Local anesthetics are injected between the muscle layers confirming the needle tip and spread of the solution. This technique will reduce incomplete effect or side effects of the obturator nerve block.
