Abstract

Background: The sacroiliac joint has a structure in which the direction of the load relative to the articular surface is irrational, as the joint surface is not perpendicular to the trunk load axis, it is likely to incur more degenerative changes than other weight-bearing joints.

Methods: This retroprospective study consisted of a total of 145 cases 104 (71.7%) men and 41 (28.3%) women who applied to Gaziantep University Medical Faculty Radiology Department Polyclinic with pelvic CT from 2013 to 2018. The mean age was 33.5 years (range: 18 to 60 years). Pelvis CT images were performed according to the exclusion criteria specified by the experienced orthopedic surgeon. Patients were excluded from the study if they were younger than the age of 18; had a condition involving the sacroiliac joint, had an endocrine disorder, or had a history of a trauma affecting the pelvis CT examination.

Results: In this current study, six types of anatomic variations were detected. Iliosacral complex variation has been determined as the most common type of variation. The incidence of variations of SJ in all cases was 28.9%. Degenerative changes were seen in 5.5% of patients fewer than 30 years of age. When it comes to the patients whose age range is 30-60, the percentage of the degenerative changes is 12.4%. In patients who were thirty years and older, the prevalence of degenerative changes increased progressively with increasing age.

Conclusions: In this study, it is thought that the knowledge of variations in normal population and degenerative changes will contribute to the better understanding of normal morphological structure of SJ and to the anatomical literature. It’s seen that there is not a statistically significant relationship between degenerative changes and anatomical variations.
