Abstract

C1–C2 fixation still poses many problems. We studied a series of odontoid process fractures [5] and post-traumatic C1/C2 dislocations. In our acute dens fractures series (59 cases), we used posterior wiring (with or without graft) in 30 cases. With this technique we obtained a complete reduction in 22 cases (73%) but on the follow-up X-rays we noted 12 secondary displacements of the dens (40%) and 4 pseudarthroses. We used the same operation with 10 C1/C2 dislocations, and we observed 5 postoperative slips (50%) and 2 pseudarthroses of the graft. In 1987, Perrin [4] published a short series of C1/C2 fixations of rheumatoid dislocation treated with CD instrumentation. We thought this idea was useful and before applying it, we made a biomechanical comparaison between wiring and CD instrumentation. This paper reports our results.
