Abstract: Objective　To measure the structural parameters of transverse process of lumbar spine and analyze the correlation between those parameters and individual height, which  providing anatomic basis for the design the improved spinal correction system.　Methods　CT images of lumbar spine in 60 patients (30 cases in male and 30 cases in female) with different height were collected, then  three dimensional models of vertebral for the 60 patients were reconstructed by Mimics software. By these models, the length, width, thickness, coronal angle and horizontal plane angle of vertebral transverse process were measured and recorded. Spearson correlation analysis was performed by SPSS22.0 to understand the correlation between transverse process parameters and height.　Results　The correlation coefficient r value of the length of L2, L5 and the thickness of L5 were between 0.2~0.4. The correlation coefficient r value of the width of L1, L3 ,L4 and the thickness of L1 were between 0.4~0.6. The correlation coefficient r value of the thickness of L2, L3 ,L4 and the width of L2 were between 0.6~0.8.　Conclusions　The width and thickness of L1~4 transverse process are positively correlated with height. The length of transverse process is weakly correlated with height. While the horizontal angle and coronal angle of transverse process has no significant correlation with height.
