Abstract

INTRODUCTION

Ring fixation of C1 can be performed using pedicle screws and a rod in case of unstable Jefferson or lateral mass fractures of C1.

MATERIALS AND METHODS

In a case series of three patients, we stabilized C1 fractures surgically using a modified technique of C1 ring fixation by using monoaxial instead of polyaxial screws. Functional outcome and pain was recorded postoperatively.

RESULTS

In this very small case series, we observed good results concerning pain and functional outcome. All fractures were bony healed within 13 weeks. In one case, a screw penetrated the spinal canal and had to be repositioned. A mild irritation of C2 nerve root occurred in two cases postoperatively.

CONCLUSION

C1 Ring fusion with monoaxial screws provides a good ability to reduce the fracture indirectly by the screws and the rod itself.

摘要

引言

对于不稳定的Jefferson骨折或C1侧块骨折，可使用椎弓根螺钉和棒进行C1环固定。

材料与方法

在一个包含3例患者的病例系列中，我们采用改良的C1环固定技术，使用单轴而非多轴螺钉对C1骨折进行手术稳定。术后记录功能结果和疼痛情况。

结果

在这个非常小的病例系列中，我们观察到疼痛和功能结果方面的良好效果。所有骨折均在13周内骨性愈合。1例中，一枚螺钉穿透椎管，不得不重新定位。术后2例出现C2神经根轻度刺激。

结论

单轴螺钉C1环融合通过螺钉和棒本身具有良好的间接复位骨折能力。
