About Tim Yoon, MD, PhD

Dr. Tim Yoon is a board-certified orthopaedic surgeon who joined The Emory Clinic in 2000. He received his BS from the Massachusetts Institute of Technology and his MD and PhD from Yale University. He was an orthopaedic resident at the University of California at San Francisco and then completed a spine surgery fellowship with Howard An, MD and Ronald DeWald, MD at RUSH Presbyterian St. Luke's Medical Center in Chicago. Dr. Yoon then became an Assistant Professor at Emory and the Chief of Orthopaedics at the Veterans Administration Medical Center at Atlanta.

Dr. Yoon has lectured and presented his research in numerous national and international meetings. He is an active member of the North American Spine Society and Orthopaedic Research Society. He has recently won the Prize for Outstanding Research from the International Society for the Study of Lumbar Spine for his work on gene therapy to stimulate intervertebral disc cell metabolism. He has authored and co-authored many research papers in leading spine journals on topics including lumbar spine mechanics, methods of spinal fixation, and biological methods of stimulating disc cells. He has written numerous book chapters and reviews on when and how to perform spinal surgery. He is on the review board of two leading spine journals.

Dr. Yoon's areas of interest include cervical spinal surgery, spinal fusion surgery, and minimally invasive techniques in spine surgery.

Case Studies Presented by Tim Yoon, MD, PhD

Thoracic Disc Herniation

Presented by: T. Yoon MD, PhD

The patient is a 58-year-old Caucasian male who presented with a chief complaint of gait disturbance. The gait disturbance had been present for one year, but it had significantly deteriorated in the previous 2 months.

Iatrogenic Facet Instability

Presented by: T. Yoon MD, PhD

The patient is a 45-year-old, Caucasian female, who presented with a chief complaint of low back pain. The patient’s history is notable for laminectomies at L3-L4 and L4-L5, performed for stenosis 2 years prior to presentation in our clinic. The outcome of this surgery was resolution of leg pain, but the patient complained of mechanical low back pain.
