Patient Testimonials

Dr. Spiker treats conditions of the neck and back such as disk herniations, spinal stenosis, cervical myelopathy and deformities of the spine. He believes in the thoughtful use of new technologies, including minimally invasive surgery and image-guided techniques. As an Associate Professor in the Department of Orthopaedic Surgery at the University of Utah, he enjoys the benefits of working closely with non operative spine specialists and physical therapists to provide comprehensive care to his patients.

Dr. Spiker’s research interests include the treatment of cervical spine disorders, spine imaging techniques and the genetics of common spinal conditions. He has authored many peer-reviewed publications and book chapters on these and other related topics.

Dr. Spiker studied Biochemistry and History and The University of California at Santa Barbara and earned his medical degree from the University of Southern California. He completed his residency in Orthopaedic Surgery at the University of Utah and a dual Orthopaedic Spine and Neurosurgical Spine Fellowship at the Rothman Institute at Jefferson Medical Center in Philadelphia, PA.
