Upper Cervical Manipulation Combined with Mobilization for the Treatment of Atlantoaxial Osteoarthritis: A Report of 10 Cases

ObjectiveThis study presents the outcomes of patients with idiopathic degenerative and posttraumatic atlantoaxial osteoarthritis who were treated with upper cervical manipulation in combination with mobilization device therapy.Clinical FeaturesA retrospective case review of 10 patients who were diagnosed with either degenerative or posttraumatic atlantoaxial arthritis based on histories, clinical symptoms, physical examination, and radiographic presentations was conducted at a multidisciplinary integrated clinic that used both chiropractic and orthopedic services. All 10 patients selected for this series were treated with a combination of upper cervical manipulation and mechanical mobilization device therapy. Outcome measures were collected at baseline and at the end of the treatment period. Assessments were measured using patients' self-report of pain using a numeric pain scale (NPS), physical examination, and radiologic changes. Average premanipulative NPS was 8.6 (range, 7-10), which was improved to a mean NPS of 2.6 (range, 0-7) at posttreatment follow-up. Mean rotation of C1-C2 at the end of treatment was improved from 28° (±3.1) to 52° (±4.5). Restoration of joint space was observed in 6 patients. Overall clinical improvement was described as “good” or “excellent” in about 80% of patients. Clinical improvements in pain and range of motion were seen in 80% and 90% of patients, respectively.ConclusionChiropractic management of atlantoaxial osteoarthritis yielded favorable outcomes for these 10 patients.
