Abstract :Aims: The aim of this study was to investigate the effect of pelvis type on the trans-sacralinsert ignore into journalissuearticles values(TS); screw corridor diameter. Methods: Pelvis computed tomography insert ignore into journalissuearticles values(CT); scans between 2017 and 2020 were retrospectively reviewed. Age, gender, height, weight and body mass index insert ignore into journalissuearticles values(BMI); of the patients were determined during the CT examination. Pelvic CT scans were examined using the imaging system\`s multi-plane reconstruction insert ignore into journalissuearticles values(MPR); mode, and the TS screw corridor was measured for both the upper and second sacral segments. In addition, pelvic incidence insert ignore into journalissuearticles values(PI);, sacral tilt insert ignore into journalissuearticles values(SS);, and pelvic tilt insert ignore into journalissuearticles values(PT); values were measured. Pelvis typing was performed using the large transverse diameter, anteroposterior diameter, interspinous, intertuberocytosis, transverse outlet diameter, sagittal mid-pelvic diameter, and sagittal outlet values. Results: 81insert ignore into journalissuearticles values(38%); male and 132insert ignore into journalissuearticles values(62%); female patients were included in the study. Gynecoid pelvis type was more common in females and android pelvis in males insert ignore into journalissuearticles values(p < 0.001);. The largest diameters in the TS screw corridor at the S1 level belonged to the anthropoid pelvis type. However, in the TS corridor at the S2 level, there was a significant difference between the pelvis-type groups in the mean values of AP and CC insert ignore into journalissuearticles values(p < 0.001);. The effect of gender difference on the TS screw corridor width at the S1 and S2 levels was significant. An adequate corridor width for the TS screw corridor was detected in 50.8% of females and 67.9% of males at the S1 level, while in 21.2% of females and 70.4% of males at the S2 level. Conclusions: There is a significant difference in the dimensions of the trans-sacral screw corridor according to the pelvis type and gender, with the largest diameter observed in the anthropoid pelvis type and males. In critical situations, especially in males and individuals with android-anthropoid pelvis, the trans-sacral screw option should be considered primarily not only for the S1 trans-sacral corridor but also for the S2 trans-sacral corridor in pelvic posterior ring injuries
