直视下寰枢椎椎弓根钉固定技术在上颈椎的应用

The Application of C1-C2 Pedicle Screw Instrument by Direct Vision in Atlas

目的探讨直视下寰枢椎椎弓根技术在上颈椎应用的可行性.方法在全麻下对12例患者进行了寰枢椎椎弓根技术固定.术中在直视下行C1-C2置钉,复位固定.后路髂骨植骨.结果24枚置钉均获得成功,复位固定满意,随访3至15月(平均4.2月),螺钉无松动或断钉,无椎动脉和脊髓损伤,3至6月植骨融合.结论直视下寰枢椎椎弓根钉技术在上颈椎的应用是安全可靠的,临床效果良好.

objective：To explore the surgical feasibility of C1 - C2 pedicle screw instrument by direct vision in atlas. Method： 12 adult patients with atlantoaxial instability were treated with C1 - C2 pedicle screws instrument by direct vision under general anesthesia. Bone graft were administered in all patients. Result： A total of 24 screws were successfully placed in atlas. All patients were followed up from 3 to 15 months, averaged 4.2 months. No cases of implant failure were observed, and there were no neural or vascular injure. All patients had a bone fusion on radiographs after three or six months. Conclusion： The application of C1 - C2 pedicle screw instrument by direct vision in atlas is safe, and the clinical result is satisfactory.
