ABSTRACT
Introduction: In the sacrococcygeal region anatomical variations are related with change in the number of sacral vertebra by union of first coccyx with sacrum. This study is carried to know the prevalence of sacralisation of coccygeal vertebra in Gujarat Method: The present study of sacralisation of coccygeal vertebra was carried out on 189 dry human sacra of gujarati population,115 male and 74 female. Result: Sacralisation of coccygeal vertebra was seen in 45(23.8 %)cases Conclusion:This study considers several issues pertaining to fusion of the coccyx to the sacrum,including prevalence,sexual differences,effect on pelvic size and obstetrical and evolutionary implications. Clinally,the sacralisation of coccygeal vertebra is of paramount importance to surgeons especially pediatric surgeons and obstetricians.as it is a less known variant.
