摘要：To facilitate the construction of intact model of fractured bone and satisfy the representation of fracture information, a novel approach of constructing a restored model of fractured femur (RMFF) based on anatomic feature is put forward. First, the fracture mesh model is divided into major segments by removing the comminuted part. Next, through the constraint-based deformation of parameterized template with a few valid parameters of fracture segments, the intact reference surface model is constructed to represent normal anatomy of individual fractured femur, and the feature points of the reference model are extracted. Then, based on the solution of matrix equations of rigid registration between available feature points of fracture segments and the ones of the reference model, major fracture segments are piecewise adjusted to original proper positions respectively. Finally, the internal part of the reference model cut with the boundary curves of major segments is employed to represent the surface of the comminuted part, and the surface of the comminuted part is merged with adjusted segments to acquire the intact model. Simulation experimental results show that RMFFs can be reconstructed rapidly and accurately according to available information of the fractured femur.
