William Thompson IV, MD Joins Arizona’s CORE Institute
Dr. Thompson will “focus on the diagnosis and treatment of complex spine and pain conditions, in addition to spinal cord stimulation trials and radiofrequency ablations.”
Dr. Thompson graduated from the Medical College of Wisconsin based in Milwaukee, Wisconsin and subsequently served as chief resident at UCLA Medical Center in Los Angeles, California. He then “completed his fellowship training in Pain Medicine at Harvard University’s Beth Israel Deaconess Medical Center” in Boston, Massachusetts.
Prior to The CORE Institute, Dr. Thompson was chief of Valley Anesthesiology and Pain Consultants’ pain division.
A leader in the medical community, Dr. Thompson is currently the vice president of the Arizona Medical Association, president of the Arizona Society of Anesthesiologists, and vice president of the Arizona Society of Interventional Pain Physicians. He has also engaged with task forces created to address the opioid epidemic.
Dr. Thompson told OTW, “As a physician coming from a single specialty group, this will provide me with more opportunities for patient care and professional growth. By integrating into a dynamic practice of board-certified orthopedic experts, I will be able to provide more efficient care to my patients at The CORE Institute and provide better outcomes for them.”
Founded as a three-physician practice in 2005, The CORE Institute now has more than 70 physicians serving patients across more than 20 locations in Arizona and Michigan. Its services and specialties include orthopedics, fractures and trauma, neurology, pain management, physical therapy, and spine care.

Discussion
This is a fascinating development. In my practice we've seen similar outcomes with the revised protocol. The key differentiator seems to be patient selection criteria. Has anyone else noticed the correlation with BMI thresholds?
Great point. I'd push back slightly on the conclusion, the sample size in the cited study is too small to draw population-level inferences. That said, the directional signal is compelling and worth a larger RCT.
We implemented a similar approach last year. Early results are promising but we're still gathering 12-month follow-up data. Happy to share our protocol if anyone is interested.
