[Contribution of dynamic radiographs in atlantoaxial subluxation in rheumatoid arthritis].

Background: Cervical spine (CS) involvement is common during rheumatoid arthritis (RA) and it is distinguished by its potential gravity.

Aim: To determinate the occurrence of atlantoaxial subluxation (AAS) by dynamic incidences X-Ray and to assess its predictive factors.

Methods: Our study included a cohort of 40 patients carrying RA, who fulfilled the American College of Rheumatology criteria, for more than 2 years.

Compared imaging of the rheumatoid cervical spine: prevalence study and associated factors.

Introduction: Cervical spine involvement is common and potentially severe in patients with rheumatoid arthritis (RA). The objectives of this study were to compare the prevalences of cervical spine abnormalities detected by standard radiography, computed tomography (CT), and magnetic resonance imaging (MRI) in patients with RA; and to identify factors associated with cervical spine involvement.

Methods: We studied 40 patients who met American College of Rheumatology criteria for RA and had disease durations of 2 years or more.
