Application of virtual reality technology in the foot fracture-assisted surgery / 中国组织工程研究

ABSTRACT

BACKGROUND:The application of virtual reality technology in preoperative simulation can reduce the risk in operation effectively and improve the quality of surgery. Virtual reality technology has very important practical significance in the application of surgery. OBJECTIVE:The reverse engineering and virtual reality technology were used to achieve the preoperative simulation of a case of Pilon fracture. METHODS:The affected bones were reconstructed according to the CT data using the patient’s ankle portion in MIMICS software, and the separated bone fractures were restored. According to the characteristics of virtual reality technology, further processing on bone model was carried out using Geomagic software;the models of the fractured bones were exported with STL format. The restored bone fragments were checked up to determine integrity in the virtual reality operation platform. These models were used to do simulated operations in the virtual reality operation platform. RESULTS AND CONCLUSION:A case of Pilon fracture was simulated by using reverse engineering and virtual reality technology preoperatively. The processed 3D model was introduced into the virtual reality system to simulate the operation and help doctors choose the type, position and direction of the surgical approach and plate;the effect is good.
