摘要
目的:测量T4椎弓根-肋骨复合体的横纵径相关数据并探讨其意义。方法:12例随机成人胸椎,男7例,女5例;平均年龄23岁(19～28岁)。采用病例自身对照分组,即同一病例、同侧T4椎弓根与椎弓根-肋骨复合体对照。所用设备为GE公司Lightspeed16排螺旋CT,自T3至T5行CT扫描及三维重建。测量参数:椎弓根横径、椎弓根-肋骨复合体横径、椎弓根纵径、椎弓根-肋骨复合体纵径、椎弓根-肋骨复合体重叠纵径。结果:T4椎弓根-肋骨复合体中的椎弓根与肋骨部分重叠,椎弓根横径与椎弓根-肋骨复合体的横径比较差异有统计学意义(P<0.05);椎弓根纵径与椎弓根-肋骨复合体纵径间比较差异无统计学意义(P>0.05),椎弓根-肋骨复合体重叠纵径与椎弓根纵径或复合体纵径间差异均有统计学意义(P<0.05)。结论:T4椎弓根-肋骨复合体中椎弓根与肋骨是部分而非完全重叠,且椎弓根或复合体的纵径均不能等同于重叠纵径。
Objective：To measure the diameter of T4 pedicle-rib compomers in normal human spines and discuss the importance of related dates.
Methods：T4 computerized tomography（CT） images,including two-dimensional,three-dimensional reconstruction,of 12 random adult patients were harvested. There were 7 males and 5 females with a mean age of 23 years（ranged,19 to 28 years）. The patients were divided into groups by self control,which means the diameter of pedicle compared with that of pedicle-rib unit in the same side of each T4. The facility was GE light speed 16. Measurement of the body specimens from T3 to T5. The parameter included the width of pedicle-rib unit compared with pedicle,the longitudinal diameter of pedicle-rib unit compared with pedicle,especially for the pedicle-rib overlap.
Results：The relationship of T4 pedicle and rib were not on the same level but overlapping. The width of pedicle-rib unit was significantly larger than that of pedicle（P〈0.05）. The longitudinal diameters of pedicle-rib unit or pedicle were significantly larger than those of pedicle-rib overlap（P〈0.05）; while there was no significantly difference between the pedicle-rib unit and pedicle（P〉0.05）.
Conclusion：The overlapping relationship of T4 pedicle and rib is partly but not whole,which means the longitudinal diameter of T4 pedicle-rib overlap should not be considered as the same of unit or pedicle.
