Abstract

The aim of this study is the evaluation of coccyx morphology and morphometry with parameters obtained through multi-detector computed tomography (MDCT) images of Turkish population in terms of sex and age groups. This retrospective study was conducted on the MDCT pelvic images of 640 (320 female-320 male) individuals between the ages of 20 and 99. The parameters of number of coccyx, the number of coccyx segment, coccyx straight length, coccyx curvature length, coccyx thickness, coccyx area, sacrococcygeal joint angle, intercoccygeal joint angle, coccyx curvature index, coccyx width, coccyx deviation angle, coccyx deviation, sacrococcygeal-horn fusion and sacrococcygeal-lateral process fusion were measured. All morphometric parameters measured on coccyx except for sacrococcygeal joint angle were found to be statistically significantly higher in males when compared with females. Sacrococcygeal joint angle parameter was found to be statistically significantly higher in females (p
