Comparative anatomy of the pelvic cavity of rat strains in a translational aspect

The anatomy of the pelvic cavity has significant importance in daily clinical applications and surgical interventions such as determining dystocia, surgery of rectal cancers and mesorectal excision, treatment of twisted pouch syndrome and percutaneous sacroiliac screw fixation, and pelvic floor disorders. This study aims to determine the diameters and area calculations of the pelvic cavity in mostly preferred rat strains (Wistar Albino, Brown Norway, Sprague Dawley, and Lewis) and investigate the suitability of rats in translational studies in which anatomical conditions are not a cause of dystocia. In this study, pelvis bones were used. Each group consisted of six rats. They were examined morphologically and morphometrically. According to the Kruskal-Wallis analysis to determine whether there is any difference between strains, significant differences were observed between the strains for the length of the symphysis, oblique diameter, true conjugate, anatomical conjugate, and diagonal conjugate parameters (p
