Description
Victoria Schouela and colleagues profile in 2026 patients whose upper neck pain may come from the small lateral joint between the first two vertebrae, the C1-C2 joint. This source is usually considered only after tests at the levels below come back negative. Fifty patients with persistent pain after such negative work-ups joined a prospective study at a specialty clinic between 2022 and 2025, receiving a guided injection of anesthetic and steroid into the joint.
At thirty minutes, 22 of 49 patients, 44.9 percent, gained at least half pain relief from the diagnostic block. Facial pain predicted a poorer response, while dominant neck pain or combined neck and head pain predicted a better one. Three months out, a third of patients still met the benefit criteria, and an immediate block response did not predict who they would be. Electric shock-like pain lowered the odds of lasting benefit, while pain on touch raised them.
