| Abstract |
| Abstract This study demonstrated that frameless
stereotaxy can be applied safely to cervical disorders caused by
rheumatoid arthritis (RA). Sixteen patients with cervical instability
including atlantoaxial instability due to RA underwent instrumentation
surgery under an image-guidance system from February 2000 through
May 2001. Neural and vascular injuries were evaluated, and postoperative
computed tomography (CT) was used to determine the accuracy of
screw placement. There were no neurovascular complications, and
screw placement was highly accurate. Image-guidance systems are
useful tools for preoperative planning and application of transarticular
and pedicular screw placement in the cervical spine of patients
with RA. |
