Abstract:
Objective:To study the the correlation between the diameter or angle of thoracic-lumber pedicle and vertebral number.Method:X-ray and CT scan were performed on 46 male spine specimens.The length of pediele screw path,the cress-section angle(e) and the sagittal angle(f) of the pedicle,the width of the inner diameter of the pediele and the distance between the two pedicles were measured.The ordinal number of T1-L5 vertebral segment was numbered by 1-17.SPSS 11.5 software was used for statistical analysis.Result:The data showed a positive linear correlation with the vertebral numbers including length of T1-L4 pedicle screw path (R2=0.716),T8-L5 pedicle width (R2=0.673),T4-L5 pedicle distances (R2=0.771),T1-T2 f-angle (R2=0.767) ,T2-T4 f-angle (R2=0.908),T12-L5 pediele e-angle (R2=0.710).The negative linear correlation with thevertebral numbers included T2-T3 pedicle width(R2=0.792),T1-T4 pedicle distances(R2=0.866),T7-L5 f-an-gle(R2=0.931),T1-T6 pedicle e-angle (R2=0.774).However,the T1-T2 and T4-T7 pediele width,the T4-T6 pediele f-angle,as well as the T6-T12 pedicle e-angle had no significant correlation with the vertebral num-bers.Conclusion:Apart from the T1-T2 and T4-T7 pedicle width,the T4-T6 pedicle f-angle and the T6-T12 pedicle e-angle,the diameter or angle of the thoracic-lumbar pedicle have correlation with the vertebral numbers with meaningful linear regression equation.
