Recent technical advances, especially the evolution of ultrasound technology, have helped to some extent in circumventing some of the limitations of epidural anesthesia. The efficacy of an epidural depends mainly on accurate placement of the catheter in the epidural space. Therefore, identification of the epidural space is the most vital part of the procedure. Obese patients represent are the most challenging group for the identification of anatomical landmarks, it is important to determine if ultrasound imaging is a useful technique in this population.
