Abstract
Cervical spine injures is an important cause of morbidity worldwide, the common causes being fall from height and road traffic accidents. Different techniques are described for the management of severe sub axial spine trauma. For stabilization of two and three column injuries, traditionally surgical fixation is done. While anterior cervical fusion with plating and screwing/corpectomy and CAGE is done anteriorly to stabilize the ventral column, many methods for stabilizing posterior column has been described. In our institution we have regularly followed two methods: either a simple posterior interspinous wiring or lateral mass screw and rod fixation .
58 cases who underwent surgery during three year period were analyzed, 47 cases available for follow up. 23 cases had interspinous wiring and 19 cases lateral mass fixation as posterior procedure along with anterior fusion. Only anterior fixation was done in 16 cases. Comparison of the two procedures in terms of stability and fusion on serial x-rays, complications, surgical time, neurological recovery and cost factor was done.
While used in conjunction with anterior fusion, the role of both interspinous wiring and lateral mass fixation are same ie. to maintain the posterior construct and provide the stability till the anterior fusion is complete. Interspinous wiring is a relatively safe, simple technique even in inexperienced hands. The duration of surgery, blood loss and radiation exposure are less compared to lateral mass fixation
