Characteristics of idiopathic atlanto-axial subluxation: a comparative radiographic study in patients with an idiopathic etiology and those with rheumatoid arthritis

Abstract

Objective Atlanto-axial subluxation (AAS) is caused by multiple conditions; however, idiopathic AAS patients without RA, upper-cervical spine anomalies or any other disorder are rarely encountered. This study retrospectively investigated the radiographic findings in idiopathic AAS patients, and clarified the differences between those AAS patients and those due to RA. Methods Fifty-three patients with AAS treated by transarticular screw fixation were reviewed. The subjects included 8 idiopathic patients (ID group) and 45 RA

Atlantoaxial Subluxation Associated With Chronic Motor Tics

“…The stability of the atlantoaxial joint is maintained by not only the transverse ligament but also the fibrous joint capsules, which work as a whole [ 7 ]. In our case, unilateral C1/2 facet joint osteoarthritis was already observed preoperatively.…”

Multimodal Management of Coexisting Atlantoaxial Subluxation and Spinal Stenosis in an Older Adult: A Case Report and Literature Review

“…Atlantoaxial subluxation, marked by a loss of stable articulation and unprovoked excessive movement at the C1-C2 junction, can cause neck pain, headache, movement restriction, weakness, numbness, and pyramidal signs in many patients [ 1 , 2 ]. This condition commonly coexists with conditions such as rheumatoid arthritis, abnormalities in the upper cervical spinal structures, Down syndrome, and infection [ 1 - 3 ]. However, it is rare and difficult to diagnose when unassociated with traumatic, congenital, or rheumatic disorders [ 2 ].…”
