With the perfect combination of the rapid prototyping technique, the clinician can accurately judge the fracture location and draw up a plan of operation. Preoperative fracture reduction and simulation obviously improve the safety and quality of the operation.?OBJECTIVE:?To evaluate the clinical value of computer-aided technology in diagnosis and treatment of pelvic fracture.?METHODS:?We collected 20 patients with pelvic fractures, who were randomly divided into the computer-aided group and the traditional surgery group. Traditional surgical method only needed X-ray and two-dimensional CT scanning of pelvis. Computer-aided group needed to extract original CT data, used MIMICS software for three-dimensional reconstruction. The models of pelvic and steel plate were made using rapid prototyping technique according to the proportion of 1:1. Performers and participants completed surgical si
