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(T_4～L_5)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 T_4 to T_8 and enlarged from T_9 to L_5.The width of the pedicle basilar part enlarged from T_4～L_5.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 T_4 to T_8 but transpedicular basilar part and trans-pedicular approach can be chosen in T_9 to L_3 and transpedicular could be used in L_4～L_5 when percutaneous vertrbroplasty is done in T_4 to L_5.
