Dr. Khoi D. Than

I have more than 25 years of experience treating patients of all ages with spinal disorders. I have had an interest in the management of spinal disorders since starting my medical education. I performed residencies in both orthopaedic surgery and neurosurgery to gain a comprehensive understanding of the entire range of spinal disorders. My goal has been to find innovative ways to manage the range of spinal conditions, straightforward to complex. I have a focus on managing patients with complex spinal disorders. My patient evaluation and management philosophy is to provide engaged, compassionate care that focuses on providing the simplest and least aggressive treatment option for a particular condition. In many cases, non-operative treatment options exist to improve a patient’s symptoms. I have been actively engaged in clinical research to find the best ways to manage spinal disorders in order to achieve better results with fewer complications.

I specialize in the surgical management of all complex cervical, thoracic, lumbar, or sacral spinal diseases by using minimally invasive as well as standard approaches for arthritis or degenerative disease, deformity, tumors, and trauma. I have a special interest in the treatment of thoracolumbar deformities, occipital-cervical problems, and in helping patients with complex spinal issues from previously unsuccessful surgery or recurrent disease. I aim to improve surgical outcomes for my patients and care of all spine patients with active research evaluating clinical and radiological results after spine surgery with multiple prospective databases. I listen to my patients to understand their symptoms and experiences so I can provide them with the information and education they need to manage their disease. I make sure my patients understand their treatment options, and what will work best for their individual condition. I treat all my patients with care and concern – just as I would treat my family. I am available to address my patients' concerns before and after surgery. Dr. Gottfried is highly rated in 8 conditions, according to our data.
