慢性関節リウマチにみられた頸椎亜脱臼の種々相

抄録

Pain and stiffness of the neck are not uncommonly seen in the patient with rheumatoid arthritis. The x-ray of those patients shows various degree of subluxations of the cervical spine.
In our cases the subluxation is most often situated at the atlanto-axial level, but is also less often observed below the second cervical level. One patient reveals the vertical subluxation of odontoid and other shows the posterior displacement of the third cervical spine. Those two patients developed the tetraparesis due to the probable damage of the spinal cord.
The degree of the cervical subluxation are closely related to the duration of disease, rheumatoid involvement of the peripheral joint, and the adequacy of the glucocorticoid therapy.
