ABSTRACT
The objective of this article is to explain the technique of C1-C2 arthrography as
a suitable treatment for pain due to C1-C2 abnormalities. The technique is consistent
with the puncture of the posterior aspect of the C1-C2 joint under fluoroscopic control.
Arthrography is performed with 1 mL of contrast media. After that, 1 mL of long-acting
steroid is injected. The articular cavity has an anterior recess and a posterior recess.
The posterior recess is large and easily punctured. In 5% of cases, the ipsilateral
joint is also opacified. This injection is indicated in cases of upper cervical pain
because of C1-C2 osteoarthritis, inflammatory arthritis of the upper spine (rheumatoid
disease, spondylarthritis), and cervico-occipital neuralgia (Arnold's neuralgia) of
the same causes or of unknown local origin. C1-C2 arthrography appears to be an efficient
and safe technique for the treatment of upper cervical pain due to C1-C2 abnormalities.
