Background rnTrauma is a public health burden resulting in increased morbidity, mortality and disability for thernsurvivors. Musculoskeletal injury results in dramatic, destructing and life-threatening injuries.Ofrnthese pelvic fracture accounts approximately to 3% of the overall injuries and is one of the majorrncauses of morbidity and mortality.Classification of pelvic fracture is useful in describing injuryrnand also helps in guiding both the initial treatment and definitive fixation. But pelvic fracturesrnhave presented a great challenge to orthopedic surgeons and radiologists over the years in thatrnmultiple classification system exists to attempt to standardize care and no consensus exists in thernclassification method of such fractures. The classification scheme of Young and Burgess andrnTiles described the severity of injury by the mechanistic process involved and by grading thernstability of the injury respectively. However, the most current classification method is thatrndeveloped by the AO and OTA and is a composite of these two earlier methods. In addition, anrnunderstanding of the mechanism of injury that leads to pelvic fractures is useful to guiderntreatment and understand patterns of injury and cause of mortality. rnObjective rnThe objective of the study is determining the CT and X-ray pattern of pelvic fracture in TASH. rnMethod rnThe study is a hospital based retrospective cross sectional study done on 80 patients who havernpelvic ring fracture who have CT scan and Pelvic X-ray (AP, Inlet and outlet views) in therndepartment of radiology. The CT scan was examined by senior radiology residents and revisedrnby radiologist, with these finding the Tiles classification of pelvic ring fracture was assessed byrnthe principal investigator initially by X-ray alone and later by CT scan alone blindly. rn rnviirn rnResult rnA total of 80 patients with pelvic ring fracture were included in the study of which 58 (72.5%)rnwere males and 22 (27.5%) were females. Road terrific accident was the major cause of pelvicrnfracture accounting for 76.3% of cases followed by fall from a height. Of those involved in RTArnthe most affected people were both passengers and pedestrians (30%) each followed byrndrivers(16.3%).The most commonly affected age group was those found in between 15-25rnyears of age (43.8%) and followed by those in between 26-35 years (35%). The most commonrnpattern of pelvic ring fracture was Tiles B2 (25%) followed by C1 (22.5%) and B3 (20%). Over allrnTiles B accounts 45% and Tiles C accounts 38.8%. rnConclusion rnIn this study trauma commonly affects males and RTA is the most common type of traumarncausing pelvic ring fracture affecting males in the productive age groups between 15-35 years.rnTiles B pattern of pelvic ring fracture is the most common pattern followed by Tiles C pattern.rnFurther study is recommended in the value of CT and X-ray in the evaluation of pelvic fracture.
