Earthquake-related crush fractures and non-earthquake-related fractures of the extremities: A comparative radiological study

OBJECTIVE: To determine the features that differentiate earthquake-related crush extremity fractures from non-earthquake-related extremity fractures by using digital radiography (DR) and multidetector row computed tomography (MDCT). METHODS: Six hundred and twenty-three consecutive victims with crush extremity fractures arising from the 2008 Sichuan earthquake, including 611 undergoing DR and 12 undergoing MDCT, entered the test group, and 316 consecutive victims with non-earthquake-related extremity fractures, including 301 undergoing DR and 15 undergoing MDCT, were enrolled in the control group. Image data were reviewed retrospectively and statistically between groups focusing on the anatomic distributions, numbers and types of extremity fractures. RESULTS: Fractures involving multiple extremities were more likely in the test group than the control group (88/623 vs 27/316 victims, P Language: en
