Calcaneal osteotomy preoperative planning system with 3D full-sized computer-assisted technology

In this study, we developed a CT-based computer-assisted pre-operative planning and simulating system for the calcaneal osteotomy by integrating different software's function. This system uses the full-scaled 3D reverse engineering technique in designing and developing preoperative planning modules for the calcaneal osteotomy surgery. The planning system presents a real-sized three-dimensional image of the calcaneus, and provides detailed interior measurements of the calcaneus from various cutting planes. This study applied computer-assisted technology to integrate different software's function to a surgical planning system. These functions include 3-D image model capturing, cutting, moving, rotating and measurement for relevant foot anatomy, and can be integrated as the user's function. Furthermore, the system is computer-based and computer-assisted technology. Surgeons can utilize it as part of preoperative planning to develop efficient operative procedures. This system also has a database that can be updated and extended and will provide the clinical cases to different users for experienced based learning.
