Aim. The aim of this study was the quantitative evaluation of anatomical variations of the sacroiliac joint in normal Turkish people according to age, gender, body mass index and childbirth in women.
Methods. This study was performed on 400 consecutive patients referred to the Radiology department of the Gaziantep University Faculty of Medicine, for pelvic computed tomography (CT) scanning for various reasons. They did not present any complaint or evidence of disease that could involve the sacroiliac joint. Patient age was equal to or higher than 15 years.
Results. Anatomical variants that we observed were accessory sacroiliac joint (70 patients, 17.5%), iliosacral complex (38 patients, 9.5%), bipartide iliac bony plate (22 patients, 5.5%), semicircular defects on iliac/sacral side (19 patients, 4.8%), crescent like iliac bony plate (14 patients, 3.5%) and ossification centers (4 patients, 1.0%). Older patients demonstrated a higher incidence of accessory sacroiliac joint (P=0.006), iliosacral complex (P=0.000), bipartide iliac bony plate (P=0.012), semicircular defects (P=0.006) and crescent like iliac bony plate (P=0.041). Obese patients had a higher prevalence of accessory sacroiliac joint (P=0.041), iliosacral complex (P=0.021) and semicircular defects (P=0.018). Semicircular defects (P=0.000) and crescent like iliac bony plate (P=0.000) were more common in women. Whereas, bipartide iliac bony plate was more observed in men (P=0.036).
Conclusion. This study has demonstrated that anatomical variations are indepentently related to age, gender, body mass ›ndex and childbirth in normal Turkish people.
