Abstract

The obturator nerve block has been shown to be a useful procedure in many clinical settings. The use of ultrasound has made this technique easier and safer to perform. It is important to know the anatomical landmarks and more espe- cially the expected motor endpoints when using a stimulating needle, so the ultrasound technique, where difficult, can augment a landmark technique. The operator should be careful of repeated attempts as the medial thigh is a highly vascular area. It is recommended where possible to use ultrasound-guided techniques.
