Abstract EN
Object.
This retrospective review was conducted to determine the surgical treatment principle for rheumatoid arthritis (RA) patients with atlantoaxial instability (AAI).
Methods.
Thirteen patients with AAI, including 5 RA patients, received preoperative computed tomography- (CT-) based image-guided navigation system (IGS) in C1 lateral mass-C2 pedicle screw-rod system fixation (LC1-PC2 fixation).
These 13 patients were analyzed for 52 screws inserted into C1 and C2.
We defined these patients as non-RA group (8 patients, 32 screws) and RA group (5 patients, 20 screws).
The neurological status for RA group was evaluated using the Ranawat classification.
The causes of AAI, surgical indications, complications, surgical method revolution, and CT-based navigation application are discussed.
Results.
None of the 13 patients expressed neurological function deterioration.
The non-RA group screw accuracy was 100%.
In the RA group, 1 RA patient developed left C2 screw loosening at 1+ months after operation due to screw malposition.
The screw accuracy for this group was 95%.
Conclusions.
Higher intraoperative surgical complication rate was described in RA patients.
Preoperative CT-based IGS in LC1-PC2 fixation can provide good neurological function and screw accuracy results.
However, for higher screw accuracy in RA patients, intraoperative CT-based IGS application may be considered.
