A 30-year-old white man comes to his general practitioner complaining of progressive low back pain over the past four years. The pain is worse at night when he lies down and improves as he moves around during the day, but it does not go away with rest.

He sought treatment from an ophthalmologist, and the symptoms resolved with steroids and eye drops. X-rays reveal some inflammatory and arthritic changes in the sacroiliac joints. Despite treatment, the disease has continued to progress, and ten years later, x-rays show calcification of the anterior spinal ligament. What is the most likely positive finding in this patient?
