Muğla Bölgesinde Sakral Dismorfizim Bulgularının Sıklığı

Abstract

ÖzThis 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.

Patterns of sacral dysmorphism in pelvic CT scans at a national referral hospital in Kenya

“…The most prevalent dysmorphic features were the presence of unfused sacral segments 67% and lack of recession of the s1 segments at 66%. This was similar to other studies where presence of unfused sacral segments was the most prevalent dysmorphic feature 70% in a German based study (4); 71% in the Iranian study(12) and 50% in the Mugla region in Turkey(13). As evidenced by these studies, un fused sacral segments may be used as a screening tool for sacral dysmorphism as it has been largely associated with the dysmorphic sacrum (sacral dysmorphism score >70) unlike other features which have been highly variable.…”

Mean S1 inlet and outlet view angles are not safe for all individuals according to three‐dimensional tomographic measurements

“…Complex three‐dimensional (3D) anatomy and the individual differences of the pelvic structures, which has a close relationship with the neurovascular structures, could complicate this surgical technique 2,6 . Therefore, it is important to understand the individual anatomical variations and the 3D structure of the pelvis during iliosacral screw application 7–10 …”
