Summary
Frameless stereotaxy is safe for treating rheumatoid arthritis (RA) cervical instability. This image-guided technique accurately placed screws, preventing neurovascular complications in patients with RA-related cervical disorders.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Rheumatology
Background:
- Rheumatoid arthritis (RA) frequently causes cervical spine instability.
- Cervical instability in RA can lead to severe neurological deficits.
- Surgical intervention is often necessary for RA-related cervical instability.
Purpose of the Study:
- To evaluate the safety and accuracy of frameless stereotaxy for cervical spine surgery in patients with RA.
- To assess the incidence of neurovascular complications associated with this technique.
- To determine the precision of screw placement using image-guidance systems.
Main Methods:
- Sixteen patients with RA-induced cervical instability underwent surgery using an image-guidance system.
- Procedures included instrumentation surgery with transarticular and pedicular screw placement.
- Postoperative computed tomography (CT) scans were used to evaluate screw placement accuracy.
- Neurovascular complications were closely monitored.
Main Results:
- No neurovascular injuries or complications were reported in any patient.
- Screw placement accuracy was found to be highly precise.
- The image-guidance system facilitated accurate surgical navigation.
Conclusions:
- Frameless stereotaxy is a safe and effective method for surgical management of cervical instability in RA patients.
- Image-guidance systems enhance precision and safety in cervical spine instrumentation surgery for RA.
- This technique minimizes the risk of complications in complex RA-related spinal procedures.
