目的探讨颈椎弓根钉内固定技术在下颈椎骨折中的临床应用方法及效果。方法对24例下颈椎骨折患者,通过术前X线、CT及三维重建检查了解椎弓根的直径、走行方向,并确定进钉点。术中凭手感及C臂斜位透视逐步扩孔,扩孔过程中探查骨孔四壁,确定为骨性,然后置入螺钉。结果经4～20个月的随访,除1例患者术后2.5个月因高位截瘫并发症死亡,1例A级患者无恢复外,其余22例均有1～3级脊髓功能恢复,无内固定失效者。结论下颈椎椎弓根内固定技术是相对安全、可靠的内固定方法,是下颈椎骨折治疗的较理想方法。
Objective Study the clinical effects of cervical transpedicular screws fixation in the treatment of lower cervical spine fractures. Methods 24 patients of lower cervical spine fractures were treated by using cervical transpedicular screws. Three dimensional reconstruction, CT and X-ray examination were used to determine the point of entering pedicle before operation. The hole of the pedicle was reamed under the oblique perspective of C-arm. The hole walls should be identified as bone, and then the screws we...
