Desh Sahni, MD, at Capital Brain & Spine is one of only a handful of Texas surgeons trained in both neurosurgery and spine surgery. He is also one of the few spine surgeons in Central Texas who specializes in minimally invasive spine surgery. Much of his work is done through incisions that are often one inch or less. Almost all his surgeries are done through a microscope with limited bleeding and tissue damage.
Most importantly, he is a highly skilled surgeon who aspires for perfection in patient outcomes. Dr. Sahni employs a scholarly, science-based approach to neurospine surgery and provides humane and compassionate patient-centric care.
Open-minded and non-judgmental, Dr. Sahni and his staff welcome all patients with warmth.
Brief Biosketch
Dr. Sahni was raised in New York and received his undergraduate degree in English literature from Columbia University and his Medical Degree from Columbia’s College of Physicians & Surgeons in Manhattan, NYC. He relocated to Texas to undergo neurosurgical training at the Baylor College of Medicine/MD Anderson in Houston. He then completed a fellowship in complex and minimally invasive spine surgery at the Texas Medical Center Spine Fellowship program where he trained at Houston Methodist Hospital, MD Anderson, and Texas Children’s Hospital. He is certified by the American Board of Clinical Neurosurgery.
Dr. Sahni has extensive experience and training in neurotrauma: both brain and spine. He is highly regarded as one of the most experienced and capable neurotrauma surgeons in central Texas. He had the privilege and honor of serving as the neurotrauma coordinator for the busiest ER in Central Texas: St. David’s South Austin Hospital, a level 2 trauma center, for 4 years and was trusted as the primary on-call neurosurgeon for their trauma center for more than 5 years. During this extremely demanding period of service to the people of Austin - where he was required to respond to emergencies in 30 minutes 24 hours a day, sometimes weeks at a time - Dr. Sahni saved the lives of and prevented paralysis in dozens of patients while relieving pain and disability in hundreds more.
Dr. Sahni believes in treating patients as he would himself and thinks compassion is a good guiding principle in one’s moral compass. He advocates for nontraditional, nonsurgical therapies for spinal health, including chiropractic care, yoga, meditation, Tai-chi, acupuncture, and strength training.
Dr. Sahni is married with three children and a 4 lb chihuahua. He is a beginner pianist who practices daily meditation, intermittent fasting, high-intensity interval training, and light resistance training.
