Introduction: The sacroiliac joint causes pain in 10 to 25% of patients with mechanical low back pain or symptoms radiating to the lower limbs. In the absence of trauma, metabolic disease, and collagen disease, its role in the pathophysiology of low back pain is not yet fully understood. The objective is to study the sagittal pelvic anatomy through the measurement of pelvic incidence (PI) in patients with sacroiliac pain in the workplace compared to asymptomatic patients. Materials and Methods: A retrospective observational analytical study of adult patients with sacroiliac pain diagnosed with CT-guided block in an occupational pathology center during January 2015 and December 2018. The comparison group was a random sample of patients without pelvic or lumbo-sacral pathology studied with CT of the pelvis and spine during the same period. Results: The mean PI in patients with sacroiliac pain was 52.57 (SD 9) and 46.52 (SD 9) in the group of healthy patients. The difference was statistically significant with the higher PI values in patients with sacroiliac pain (p 0.042). Conclusion: Patients with sacroiliac pain had a higher pelvic incidence than healthy patients, with a statistically significant difference in our study.
