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.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
