Official Title: Evaluation of Ultrasound-Guided Popliteal Sciatic Nerve Blockade in the Severely and Morbidly Obese Populations
Brief Summary: One technique for the nerve block involves injecting the numbing medicine where the nerve is together (higher up in the back of the thigh). The other technique involves injecting the numbing medicine where the nerve splits into two parts. By injecting numbing medication around the nerve(s), there will be less pain after the procedure. It is thought that the numbing medicine will be easier to inject in the group that the nerves are split. It is expected that subjects may need less pain medication and have lower pain ratings in this group too.
