This new case series, managed by the Department of Orthopedics, in the General Military Hospital of Beijing, China, involved 10 patients with idiopathic degenerative and posttraumatic atlantoaxial osteoarthritis. They were treated with upper cervical chiropractic adjusting, in combination with mobilization device therapy.

Outcome measures included self-reported pain using a numeric pain scale (NPS) (1-10, with 0 is no pain and 10 is the worst possible pain), physical examination findings, and radiologic changes.

The reported results were quite impressive:

  • Pre to post pain findings included a reduction of pain from 8.6 to 2.6
  • Rotation of C1 upon C2 increased from 28° to 52°, effectively doubling upper cervical range of motion.
  • Restoration of joint space was observed in 6 patients
  • Clinical improvement was rated as “good” to “excellent” by 80% of these patients!
