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。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,C4C5,C6（P0.05）,C5,C6C7（P0.01）;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′）（P0.01﹚,PL1（PL1′）PL2（PL2′）（P0.01）.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.
