ABSTRACT
We compare the safety and efficacy of locked and non-locked plating systems with retrospective review of 51 consecutive acute cervical injury patients who underwent anterior cervical plating procedures. The two groups were comparable in demographic details, mean age(locked 40.8, non-locked 37.9), average fusion level(locked 1.53, non-locked 1.67) and fusion rate(locked 100%, non-locked 86.7%). Hardware related complication in locked plate group was seen in one patient(2.78%), but did not required the reoperation. In the non-locked plate group, 4 patients developed screw loosening and, in 1 patient, the inferior screw was found to be 2mm posterior to posterior cortex. Reoperation was needed for this case due to symptomatic myelopathy. In the non-locked plate group instrument related reoperations was done in 5 patients(33.4%) and longer operation time was required than locked system. In this study, anterior cervical fusion with plating was nessessory for stabilizing of acute cervical instability and improving neurological outcome and fusion rate. For this purpose, locked system was theoratically safter and technically easier than non-locked system.
