The cervical spine is frequently involved in patients who have rheumatoid arthritis. The prevalence of involvement of the cervical spine has varied among studies and according to the criteria used to define involvement. Garrod reported that 178 (35.6 per cent) of 500 patients had involvement of the cervical spine, whereas Pellicci et al. reported that forty-six (43 per cent) of 106 patients had such involvement. Conlon et al., using broader criteria for involvement, found a prevalence of 88.6 per cent (295 of 333 patients).
Neurological signs, including myelopathy, are less frequently associated with rheumatoid arthritis but have been found in a sizable number of patients. The most common site of involvement of the cervical spine is the atlanto-axial articulation9. Erosion of the atlanto-axial joints and supporting ligaments can lead to subluxation of the first cervical vertebra relative to the second cervical vertebra11. Subaxial instability also has been reported . . . [Full Text of this Article]
