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.
