Abstract

Background: The sacrum is a large triangular bone formed by fusion of five sacral vertebrae and wedged between two hip bones. Dimension of sacrum varies from region to region therefore morphometric study of sacrum in population of Bihar is important for proper fixation during orthopedic procedure in trauma patients.
Objective : The objectives of this study was to evaluate the morphometric parameters of sacrum so that a data can be generated from local population.
Materials and Methods: The present study was done on 110 human sacra of known sex (62 male and 48 female) collected from department of Anatomy, IGIMS, Patna and also from other medical colleges of Bihar. Maximum length of sacrum, curved length of sacrum, maximum breadth of sacrum, antero-posterior diameter of the body of first sacral vertebra, transverse diameter of the body of first sacral vertebra and maximum length of articular surface of sacrum were measured.
Result: Mean value of sacral straight length were 104.55 cm in male and 94.66 cm in female, Curve length 112.03 cm in male and 103.98 cm in female, Width of sacrum 101.53 cm in male and 105.67 cm in female. Transverse diameter of body of 1st sacral vertebra were 46.53 cm and 40.85 cm in male and female respectively, antero-posterior diameter of body of 1st sacral vertebra were 29.89 cm and 27.73 cm in male and female respectively, Length of auricular surface were 56.08 cm and 54.77 cm respectively. Sacral index, curvature index, index of body of first sacral vertebra, corpora-basal index and auricular index were calculated.
Conclusion: Morphometric study of sacrum in population of Bihar is important because dimension of sacrum varies from region to region and this is important for proper fixation during orthopedic procedure in trauma patients.
