Abstract

Abstract:

BACKGROUND: The rapid development of computer technology has realized the leap from two-dimensional image to three-dimensional image. 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 simulation training before the operation. Time used in surgery and volume of blood loss during operation were recorded, and compared with the traditional surgery.
RESULTS AND CONCLUSION: What seen in the operation was very similar to what seen from the preoperative model of pelvic fracture. The preoperative practice made participants more tacit understanding, resulting in operating quicker and more accurate. All patients of computer-aided group got good fracture reduction, intraoperative steel plate bending more fitting for bone, the length of the steel nail was more appropriate, the location was better. Compared with traditional surgery, computer-assisted surgery had less blood loss, shorter operation time and more statistically significant difference (P < 0.05). Computer-aided clinical surgery has characteristics of small trauma, more accurate, more safety for patients and medical staffs, and has broad application prospects in orthopedics and other departments.
