Board-certified orthopaedic surgeon and fellowship-trained spine specialist Dimitriy Kondrashov, MD provides experienced care for complex spinal disorders. He joined Southern California Orthopaedic Institute (SCOI-UCLA) in 2024 with over 20 years of experience in orthopaedic surgery.
Dr. Kondrashov earned his Bachelor of Arts degree, graduating magna cum laude, from the University of Pennsylvania. He then completed his Doctor of Medicine degree at Albert Einstein College of Medicine in the Bronx, New York and was awarded the Alumnae Scholar Award.. Following his graduation, Dr. Kondrashov pursued an orthopaedic surgery residency at Long Island Jewish Medical Center, affiliated with Albert Einstein College of Medicine, in New Hyde Park, New York. He then completed his orthopaedic spine surgery fellowship through the Stanford-San Francisco combined program at Stanford University Hospital in Palo Alto and St. Mary’s Hospital in San Francisco under the guidance of Dr. Eugene Carragee, the chief editor of the Spine Journal, and Drs. Zucherman and Hsu, co-inventors of the X-STOP interspinous process decompression. Dr. Kondrashov has been an Associate Program Director of the San Francisco Orthopaedic Residency Program and Director of Orthopaedic research for more than a decade, teaching multiple future orthopaedic surgeons. He was awarded Teacher of the Year Award twice by the residents.
Dedicated to advancing spine care, Dr. Kondrashov is actively involved in multiple academic spine associations. He is a member of the American Academy of Orthopaedic Surgeons, Cervical Spine Research Society, North American Spine Society, and Scoliosis Research Society. As a testament to Dr. Kondrashov’s commitment to furthering spine care, he has more than 40 peer-reviewed research publications in spine surgery and spine biomechanics.
