This retrospective study aims to reveal the prevalence of sacral dysmorphism, the proportion of its findings and signs and its clinical importance in pelvic surgeries. 1753 nontraumatic pelvic and lower abdominal CT images were analyzed to reveal the sacral abnormal anatomy and dysmorphic signs in nontraumatic patients. Of the patients included in the study; S1-S2 residual disc in 879 (50.60%), the presence of mammillary body or mammillary process in 209 (12%), acute ascending descent in 182 (10.47%), tongue-in-grove sign in 178 (10.25%), deformity in the neural foramen in 168 (9.67%), and collinearity in 121 patients (7%) were detected. The parameters of non-circular amorphous first sacral foramen and lumbosacral disc distance being close to the iliac wing (collinearity) parameters were statistically significantly higher in women than in men (p=0.027; p=0.005). There was no statistically significant correlation between non-circular amorphous first sacral foramen and collinearity parameters and gender (phi=0.149, p=0.027; phi=-0.188, p=0.005). Noncircular amorphous first sacral foramen and residual disc distance between S1 and S2 were found to be statistically significantly higher in the cases (p=0.039). Sacral dysmorphism is an abnormal anatomy that is seen much more common than it is thought in the population and plays an important role in clinical interventions. Keeping this anatomical difference in mind during surgical procedures involving sacrum reduces the possibility of encountering unwanted complications. |
