On April 20, 2013, a 7.0-magnitude earthquake hit Lushan County, Ya’an City, Sichuan Province in southwest China. West China Hospital of Sichuan University, the largest and best hospital in Sichuan Province, is located in the city of Chengdu—about 100 km from the epicenter—and provided medical treatment to a total of 400 seismic patients. In this article, we retrospectively investigated 199 patients with musculoskeletal injuries who were treated in the Department of Orthopedics. Based on the seismic intensity distribution map, injury-occurring locations were divided into 5 grade-related areas: IX, VIII, VII, VI, and ≤V grade-area. The characteristics of seismic injuries were analyzed according to the geographic distribution of victims. We found that the constituent ratio of injury causes significantly differed in different earthquake areas according to the seismic intensity.
