Abstract
|
|
|
Purpose : This study explores the application examples of 3D printing technology in clinical environment, specifically in bone fracture surgery. CT images stored in clinical PACS were processed to produce the fracture model by 3D printer, and simulate for surgery planning, through which more rapid and accurate operation was targeted.
Materials and Methods : The subjects were 13 patients who were hospitalized in the Chungbuk National University Hospital, with clavicle fracture by traffic accident or sports etc. Volume rendering technique was used to visualize the fracture and remove the surrounding tissues. 3D computer graphics fracture model was made and stored as STL file and transformed to G-code file at SD card, and used to make the facture model by 3D printer.
Results : 3D printed facture model enabled the clinical simulation and surgery planning, through which the size and fixation angle and location of metal plate could be decided.
Conclusion : As the additively manufactured fracture model has the same size and shape with the patients’ fracture, surgeons will be able to carry it into operating room to shorten the operation time and prevent secondary damage.
