Morphologic Characteristics of Atlantoaxial Complex in Rheumatoid Arthritis and Surgical Consideration Among Chinese

Abstract

The work provides detailed bony data on the rheumatoid C2 isthmus and C1 structure. Anatomic variation in either side or both sides of the C2 isthmus is severe during erosion in patients with RA. Unilateral C1-C2 transarticular screw, modification of screw diameter, or alternative techniques for C1-C2 arthrodesis should be considered in most Chinese rheumatoid cases.
