A subgluteal approach to the sciatic nerve in adults at 10 cm from the midline.

Background And Objectives: In 2003 we introduced the concept of a sciatic nerve block performed in the midgluteal area at a fixed distance from the midline in all adults regardless of gender and/or body size. The anatomic basis for that study suggested that a subgluteal block could also be accomplished in a similar fashion.

Methods: After informed consent, 20 patients were prospectively recruited.
