Background: The present study was aimed to study and develop in-depth understanding of the effect of the coronal angulation of sacral vestibule S2 on morphometry of sacral vestibule in North-West Indian population presenting to our institution, which will go a long way in planning to treat the posterior pelvic injuries with percutaneous screws, thereby reducing the morbidity associated with open fixation. Methods: This study was conducted in the Department of Orthopaedics and Radiodiagnosis at Dr. Rajendra Prasad Govt. Medical College, Kangra at Tanda over a period of one year. All the patients of the age >18 years and above submitting for either abdominal, lower spinal or non-orthopaedic pathology of pelvic region, presenting for computed tomography to the Department of Radiodiagnosis were included in the study. Results: The coronal angulation of S2 vestibule ranged from 1° to 10° with a mean of 5.06°±2.77°. There was a weak relation between coronal angulation of S2 and age-groups 18-30 years (r=0.105; P=0.186), 31-40 years (r=0.040; P=0.715), 41-50 years (r=-0.085; P=0.330), 51-60 years (r=0.119; P=0.079), and >60 years (r=-0.166; P=0.605). There was non-significant difference in coronal angulation of S2 (P=0.913) between males and females. There was a weak relation between interspinus distance with coronal angulation of S2 (r=0.069; P=0.090). There was no relation between height with coronal angulation of S2 (r=0.019; P=0.631). Conclusion: The present study, the first of its kind in North Western part of India arrived to help us anthropometric measurements of sacral vestibule, thereby, helping in development of local protocols for percutaneous fixation in sacral fracture.
