Background Trauma is a public health burden resulting in increased morbidity, mortality and disability for the survivors. Musculoskeletal injury results in dramatic, destructing and life-threatening injuries.Of these pelvic fracture accounts approximately to 3% of the overall injuries and is one of the major causes of morbidity and mortality.Classification of pelvic fracture is useful in describing injury and also helps in guiding both the initial treatment and definitive fixation. But pelvic fractures have presented a great challenge to orthopedic surgeons and radiologists over the years in that multiple classification system exists to attempt to standardize care and no consensus exists in the classification method of such fractures. The classification scheme of Young and Burgess and Tiles described the severity of injury by the mechanistic process involved and by grading the stability of the injury respectively. However, the most current classification method is that developed by the AO and OTA and is a composite of these two earlier methods. In addition, an understanding of the mechanism of injury that leads to pelvic fractures is useful to guide treatment and understand patterns of injury and cause of mortality. Objective The objective of the study is determining the CT and X-ray pattern of pelvic fracture in TASH. Method The study is a hospital based retrospective cross sectional study done on 80 patients who have pelvic ring fracture who have CT scan and Pelvic X-ray (AP, Inlet and outlet views) in the department of radiology. The CT scan was examined by senior radiology residents and revised by radiologist, with these finding the Tiles classification of pelvic ring fracture was assessed by the principal investigator initially by X-ray alone and later by CT scan alone blindly. vii Result A total of 80 patients with pelvic ring fracture were included in the study of which 58 (72.5%) were males and 22 (27.5%) were females. Road terrific accident was the major cause of pelvic fracture accounting for 76.3% of cases followed by fall from a height. Of those involved in RTA the most affected people were both passengers and pedestrians (30%) each followed by drivers(16.3%).The most commonly affected age group was those found in between 15-25 years of age (43.8%) and followed by those in between 26-35 years (35%). The most common pattern of pelvic ring fracture was Tiles B2 (25%) followed by C1 (22.5%) and B3 (20%). Over all Tiles B accounts 45% and Tiles C accounts 38.8%. Conclusion In this study trauma commonly affects males and RTA is the most common type of trauma causing pelvic ring fracture affecting males in the productive age groups between 15-35 years. Tiles B pattern of pelvic ring fracture is the most common pattern followed by Tiles C pattern. Further study is recommended in the value of CT and X-ray in the evaluation of pelvic fracture.
