Two Cases of with Cutout of Wire or Looseness Behind Cervical Fixation for RA

Abstract

In RA cases requiring fixation, wire cannot be passed if the bone is weak.
We experienced two cases of cutout and looseness of wire with the occipital after occipito-cervical posterior fusion for RA.
We performed re-fixation using the Tekmilon cable system instead of wire. By positioning the bar hole of the occipital at the caudal of the inion, good fixability was obtained.
These results suggest that the Tekmilon cable system applies stress dispersively, and that cutout of wire does not occur easily. This allows operations to be carried out comparatively safely.
