【摘要】 目的:研究经皮椎弓根基底穿刺途径的影像学特点,探讨在影像监视下经椎弓根基底部穿刺的安全操作范围。方法:12具成人防腐（T₄～L₅）脊柱标本,螺旋CT扫描后测量经椎弓根基底穿刺角度、基底部大小。运用统计软件系统比较各参数的变化。结果:椎弓根基底夹角T₄～T₈逐渐减小,T₉～L₅逐渐增大。椎弓根基底大小T₄～L₅逐渐增大。左右两侧无显著性差异。男女间对比无显著性差异。结论:T₄～L₅行椎体成形术时,T₄～T₈可经椎弓根基底入路,T₉～L₃根据实际情况可选择经椎弓根或经椎弓根基底入路。L₄、L₅经椎弓根途径。更多还原

【Abstract】 Objective:To explore the characteristic of percutaneous transpedicular basilar part puncture on dimensional images and its safe procedure under image guidance.Methods:12 human spines（T₄～L₅）were gathered from preservative cadavers.Com- puterized Tomography（CT）was used for scanning.In the transverse section of the pedicle,the angles and the width of the pedicle basilar part were measured and the statistical analyses were made.Results:The angles of the pedicle basilar part diminished from T₄ to T₈ and enlarged from T₉ to L₅.The width of the pedicle basilar part enlarged from T₄～L₅.There was no significant difference in these parameters between male and female groups or between left and right sides.Conclusion:Transpedicular basi- lar part approach could be used in T₄ to T₈ but transpedicular basilar part and trans-pedicular approach can be chosen in T₉ to L₃ and transpedicular could be used in L₄～L₅ when percutaneous vertrbroplasty is done in T₄ to L₅.更多还原
