Background
Long bone fractures are a type of physical damage with high incidence rates that have serious impacts on the normal lives of humans.
Aims
How to obtain a preoperative internal fixation plate model before cutting muscle has become a critical issue.
Materials and Methods
In this paper, we present a new personalized modeling system for internal fixation plates in long bone fracture surgery. This system can achieve straight semi‐automatic processing from CT images to 3D models. First, broken bones are separated in CT images. Second, the axes of long broken bones are extracted using 3D models. Third, the vertices on the broken bone cross‐sections are segmented. Fourth, rough alignment and fine registration are implemented.
Results
An internal fixation plate is reconstructed for a long bone fracture.
Discussion
Three validations indicate that this method framework is reasonable and feasible.
Conclusion
This system can provide technical support for the personalized, minimally invasive and accurate operation on long bone fractures.
