📢 New Research on Chiropractic Neck Adjustments & Artery Dissection
A large new 2026 study provides important information about a question we occasionally hear from patients: Do chiropractic neck adjustments increase the risk of a cervical artery dissection (a rare tear in an artery of the neck)?
Researchers studied 862,984 adults who sought care for a new episode of neck pain or headache.
They compared patients who received chiropractic cervical spinal manipulation with similar patients who received medical care and were prescribed ibuprofen.
The study found NO increased risk of cervical artery dissection following chiropractic cervical manipulation.
Within 30 days:
• Chiropractic group: 31 cases among 431,492 patients
• Medical/ibuprofen group: 58 cases among 431,492 patients
One of the most important points from this research is that a developing cervical artery dissection can itself cause neck pain or headache before it is diagnosed. In other words, some patients may seek treatment for symptoms that are actually being caused by an artery problem that has already begun.
This is why a thorough history and examination—and recognizing when symptoms require medical evaluation—is such an important part of caring for patients with neck pain and headaches.
The researchers appropriately caution that this was an observational study and does not prove that a cervical artery dissection could never occur following manipulation. However, in this very large group of patients, chiropractic cervical manipulation was not associated with an increased risk of cervical artery dissection compared with medical treatment.
It's encouraging to see large-scale research continue to help us better understand both the effectiveness and safety of the care we provide.
