OBJECTIVE: To evaluate whether cervical spine changes are associated with the destruction of shoulder or peripheral joints and with bone mineral density (BMD) in patients with long-term RA. METHODS: An inception cohort of 67 patients with seropositive and erosive RA were followed up for 20 years. Cervical spine, shoulder, hand and foot radiographs, and the BMD of the lumbar spine and femoral neck were evaluated. RESULTS: A positive relationship was detected between the occurrence of atlantoaxial disorders and the destruction of both shoulder (p < 0.001) and peripheral (p = 0.001) joints. In addition, the severity of anterior atlantoaxial subluxation and atlantoaxial impaction positively correlated with the grade of destruction in the evaluated joints. Furthermore, patients with atlantoaxial disorders presented decreased BMD of the femoral neck (p = 0.019). The occurrences of subaxial subluxations (SAS) and subaxial disc space narrowings only associated with higher onset age of RA. CONCLUSIONS: Patients with severe RA and osteoporosis have an increased risk for atlantoaxial disorders. The co-existence of shoulder destruction and cervical spine disorders makes the differential diagnosis of shoulder and neck pain challenging.
