Dr. Patel serves as the chief of orthopedic spine surgery at the University of Colorado. He earned a bachelor's degree in mechanical engineering and worked as an engineer before earning both a master's of arts and a doctor of medicine degree at Washington University in St. Louis. Dr. Patel has trained in orthopedic spine surgery at the Univesity of California, San Fransicso and at St. John’s Hospital in Santa Moncia with respected orthopedic surgeons, including Drs. Michael Kropf, Hyun Bae, Rick Delamarter, Ed Dawson, Serena Hu, and David Bradford.

Dr. Patel's work has been widely published, and he presents it frequently at national and international conferences. He currently focuses on spinal non-fusion technologies, cervical and lumbar disc replacement, dynamic stabilization, alternative bone graft materials for fusion, minimally invasive surgical techniques and computer-assisted surgery.

He has extensive clinical and surgical experience with cervical, thoracic and lumbar spinal disorders.

As an academic spine surgeon, it is my responsibility to stay involved in the latest spine care research findings, techniques, and technologies.  I then look to my training and experience to judge which might be the best for each individual patient without increasing the risk of complications.  I can thus choose the best technology for my patients based on their condition and expectation from surgical treatment. Surgery, is however, a last resort to be chosen only if conservative measures fail to provide sufficient relief. 

Dr. Patel currently focuses on spinal non-fusion technologies, cervical and lumbar disc replacement, dynamic stabilization, alternative bone graft materials for fusion, minimally invasive surgical techniques and computer-assisted surgery.  His basic science research includes the study of stem cell therapies, spinal biologics, spinal biomechanics, and the evaluation of pain.

Bachelors: University of Illinois, Urbana, IL
Medical Degree: Washington University in St. Louis
Residency: University of California, San Francisco
Fellowship: Spine Institute in Santa Monica
