Abstract :

Background: The present study was aimed to study and develop in-depth understanding of the effect of the length of sacral vestibule S1 and 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 length of vestibule of S1 and S2 ranged from 98.60 to 128.2 mm with a mean value of 112.08�6.21 mm and from 108.20 to 128.60 mm with a mean of 128.60�11.85 mm respectively. There was a weak relation between length of vestibule of S1 and age-groups 18-30 years (r=0.042; P=0.595), 31-40 years (r=0.016; P=0.885), 41-50 years (r=-0.128; P=0.140), 51-60 years (r=0.005; P=0.945), and >60 years (r=-0.107; P=0.740). There was a weak relation between length of vestibule of S2 and age-groups 18-30 years (r=0.025; P=0.758), 31-40 years (r=0.002; P=0.987), 41-50 years (r=-0.130; P=0.134), 51-60 years (r=-0.093; P=0.173), and >60 years (r=-0.406; P=0.190). There was significant difference in length of vestibule of S1 (P=0.001) and S2 (P=0.041) between males and females. There was a weak relation between interspinus distance with length of vestibule of S1 (r=0.501; P=0.001) and S2 (r=-0.012; P=0.759). 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.
