摘要
目的:设计并运用下颈椎经关节螺钉导向配套器械,为临床提供帮助。方法:设计生产下颈椎经关节螺钉导向配套装置,运用2具带有头颅的颈椎标本检验,并应用于17例临床患者,植入下颈椎经关节螺钉68枚。结果:应用下颈椎经关节螺钉导向配套装置植入下颈椎经关节螺钉顺利,解剖后发现螺钉位置好,无关节突劈裂等,患者植入后经3～12个月随访,无神经受累症状,未发现螺钉松动。结论:运用下颈椎经关节螺钉导向配套器械植入下颈椎经关节螺钉,方便实用,有临床推广价值。
Objective：To design and apply the instruments for implantation of transarticular screws in low cervical spine and to evaluate the value. Methods ：Two cadavers were used to explore the value of the instruments. Seventeen patients who suffered from cervical diseases were also included in the group,sixty-eight transarticular screws inserted by use of the instruments. Results：All transarticular screws were implanted ease in the low cervical spine without split of facets, guided by the in- struments. All patients were followed up three to twelve months. Neither neurologic deficit nor failure of internal fixation was found due to implantation of transarticular screws. Conclusion ：Transarticular screws can be inserted safely and smoothly guid- ed by the instruments, which have values to be introduced widely.
