The aim of this study was to evaluate the demography and Computed Tomography scan findings in Chance fracture of the spine.  </p> <p><strong>Method</strong>: </p> <p>A retrospective study was conducted at the National Trauma Center, National Academy of Medical Sciences over a period of one year (December 2019 to December 2020). Demographic data, mechanism of injury, and computed tomographic findings of Chance fracture were recorded.  </p> <p><strong> </strong><strong>Result: </strong></p> <p>Computed tomography scans of 41 patients with Chance fracture were identified. Fall injury (76%) was the most common cause of Chance fracture followed by road traffic accidents. This fracture was most commonly seen in thoracolumbar junction TLJ (D10-L2); with L1 being the most affected vertebra (36.5%). Among posterior elements, facet distraction (84%) was the most common finding followed by lamina fracture (83%), and pedicle fracture (68%). Regarding vertebral body fracture, involvement of both superior and inferior endplates were common than isolated involvement of either one of them. CT revealed that a burst component was a common finding (68%) in Chance fracture.</p> <p><strong> </strong><strong>Conclusion</strong>:<strong> </strong></p> <p>Chance fracture was commonly caused by fall injury in our context which is higher in incidence than previously reported. More than half of patients with Chance fracture also had Burst-type components that could influence surgical management. Computed tomography scans is a useful imaging modality for the assessment of Chance fracture and burst component.<br /><br /><br /></p>}, number={1}, journal={Nepalese Journal of Radiology}, author={Bhattarai, Mamata and Thapa , Bikash Raj and Khadka, Sujan and Thapa, Govardhan}, year={2021}, month={Jun.}, pages={5–11} }
