Dr. John W. Chatas is a board-certified anesthesiologist and fellowship-trained interventional pain specialist with more than 30 years of experience treating complex spine and nerve-related pain. He is a member of Michigan Pain Specialists in Ann Arbor, where he focuses on advanced, minimally invasive solutions for patients who have not responded to traditional therapies.

Dr. Chatas is widely recognized for his expertise in sacroiliac (SI) joint dysfunction and spinal cord stimulation (SCS)—two of the most rapidly evolving areas in modern pain medicine. His clinical approach emphasizes precise diagnosis, image-guided interventions, and the use of cutting-edge technologies to restore function and improve quality of life.

– Minimally Invasive SI Joint Fusion
– Spinal Cord Stimulation (SCS)
– Peripheral Nerve Stimulation (PNS)
– Chronic Low Back and Post-Surgical Spine Pain
– Fluoroscopic and Ultrasound-Guided Interventions

Dr. Chatas has contributed to clinical research advancing the treatment of chronic pain, particularly in the areas of SI joint fusion and neuromodulation.

Dr. Chatas is a co-author of a peer-reviewed study published in the Journal of Pain Research evaluating outcomes of a novel minimally invasive posterior SI joint fusion device, specifically in patients with prior implanted pain therapies. This work highlights his role in advancing treatment options for complex, treatment-resistant SI joint pain.

In addition, Dr. Chatas has participated in multicenter clinical research evaluating spinal cord stimulation technologies, including studies involving modern SCS systems used to treat chronic low back pain. His involvement reflects a commitment to bringing evidence-based, next-generation therapies into clinical practice.

Dr. Chatas believes that successful pain management requires more than symptom control—it requires restoring function, independence, and quality of life. He takes a comprehensive and individualized approach to care, combining the following:

– Careful diagnostic evaluation
– Minimally invasive procedures
– Thoughtful use of advanced technologies
– Dr. Chatas’s goal is to help patients return to the activities that matter most to them.
