To compare stability and subsidence associated with 3 types of cervical spine stabilisation.
The C3 to C4 vertebrae of 28 Polish pigs were used. Pigs with intact vertebrae (group 1) underwent standard anterior cervical discectomy (group 2), followed by stabilisation using a cage alone (group 3), a cage with plate (group 4), or a plate-cage (group 5). Cervical spine stability and subsidence were compared in all 5 groups.
Stability was significantly increased after stabilisation by a cage with plate or a plate-cage, but not by a cage alone. The difference between stabilisation by a cage with plate and a plate-cage was not significant. Subsidence was maximal after the cage-alone stabilisation (3.1 mm), being 1.6 mm after the cage-with-plate and plate-cage stabilisations.
Additional plating as a supplement to anterior interbody cervical cage stabilisation significantly improves segmental stability and subsidence.
比较3种颈椎稳定术的稳定性和下沉情况。
使用28只波兰猪的C3至C4椎体。椎体完整的猪（第1组）接受标准的颈椎前路椎间盘切除术（第2组），随后分别单独使用椎间融合器进行稳定（第3组）、使用椎间融合器加钢板进行稳定（第4组）或使用钢板-椎间融合器进行稳定（第5组）。比较所有5组的颈椎稳定性和下沉情况。
使用椎间融合器加钢板或钢板-椎间融合器进行稳定后，稳定性显著提高，但单独使用椎间融合器则未提高。使用椎间融合器加钢板和钢板-椎间融合器进行稳定之间的差异不显著。单独使用椎间融合器稳定后的下沉最大（3.1毫米），使用椎间融合器加钢板和钢板-椎间融合器稳定后的下沉为1.6毫米。
额外使用钢板作为颈椎前路椎间融合器稳定术的补充可显著提高节段稳定性并减少下沉。
