摘要：

目的：比较颈椎椎弓根标本与CT图像测量椎弓根相关径线的差异，为临床颈椎椎弓根置钉手术前CT图像对椎弓根相关径线测量结果的临床应用提供依据。方法：分别在27具中国成人干燥颈椎（C3～C7）标本和CT图像上测量椎弓根高度(PH、PH′)、宽度(PW、PW′)、椎弓根轴线的骨性通道全长(TL、TL′)、两种椎弓根长度（PL1、PL2，PL1′、PL2′）进行线性测量，比较标本测量结果与CT测量结果两组数据的差异。结果：在同侧颈椎标本或CT图像上，不同节PW(PW′):C3、C4＜C5、C6（P<0.05)，C5、C6＜C7（P<0.01)；PH(PH′):各节之间差异无统计学意义；TL、PL1和PL2(TL′、PL1′和PL2′):不同节间差异无统计学意义；在同一颈椎标本或CT图像上，相同节段PW(PW′)＜PH(PH′)(P<0.01﹚，PL1(PL1′)＜PL2(PL2′)(P<0.01)。CT图像上各径线的测量值与对应标本测量值差异无统计学意义（P>0.05）。结论：颈椎标本与CT图像测量椎弓根相关径线结果无明显差异，提示术前CT图像测量对颈椎成功置钉手术可提供可靠的参考依据。

Abstract:

Objective
To compare the difference between the measurement results of the cervical pedicle specimens and CT image，and provide the basis for clinical cervical screw internal fixation operation. Methods Twenty-seven Chinese adult cadaver cervical specimens including C3 to C7 vertebrae were measured by a digital calipers and CT image，containing pedicle height（PH,PH′）,pedicle width(PW,PW′),total pedicle length(TL,TL′)and two pedicle lengths（PL1,PL2;PL1′，PL2′）.The results of specimens and CT images were compared. Results Different cervical vertebra in the same side of specimens or CT images,PW(PW′):C3,C4＜C5，C6（P<0.05)，C5，C6＜C7（P<0.01) ； PH(PH′):there were no significant differences；TL,PL1，PL2 (TL′，PL1′,PL2′):there were no marked differences.In the same cervical vertebra of the specimens or CT images,PW(PW′)＜PH(PH′) (P<0.01﹚，PL1(PL1′)＜PL2(PL2′) (P<0.01).Conclusion The results of measurement by CT images are not markedly different from that of specimens. CT image measurement is available before cervical screw internal fixation operation.
