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.
