Dr. Zelenty has a specific interest in minimally invasive surgical techniques used for adult spinal deformity including laterally based interbody fusions. In addition, he works in conjunction with his colleagues in the Department of Anesthesiology, Critical Care & Pain Management to do clinical research on postoperative pain management strategies for spinal surgery including an ongoing randomized controlled trial involving continuously delivered local anesthesia.
