This article describes the use of minimally invasive posterior cervical arthrodesis and internal fixation for the subaxial cervical spine. Such systems vary by the angulation of their screws and in the degree of the constraint placed at the screw-rod interface. The polyaxial tulip or islet connectors of the screws are able to angle medially, laterally, and straight, with varying degrees of rotational freedom in each direction, thus making segmental fixation more easily achievable from a top-loading approach and allowing for the possibility of minimally invasive posterior cervical fixation.
本文描述了微创后路颈椎关节融合术及内固定术在颈椎下颈椎节段的应用。此类系统因螺钉角度及其在螺钉-棒界面处的约束程度而异。螺钉的多轴郁金香形或小岛形连接件能够向内侧、外侧及直线方向成角,在每个方向上具有不同程度的旋转自由度,从而使经顶部加载入路更易于实现节段固定,并使得微创后路颈椎固定成为可能。
