Abstract:

BACKGROUND: During the prosthesis assembly, an absolutely matched three-dimensional model is required.
OBJECTIVE: Through the exploration of reverse engineering/forward design technique to find a fast and accurate method for reconstruction of a three-dimensional model of hip surface replacement prosthesis.
METHODS: Based on point cloud file from the three-dimensional laser scanner, proximal femur component, acetabular component were reconstructed by the Geomagic and 3ds max software.
RESULTS AND CONCLUSION: The three-dimensional reconstruction distinctly displayed the structures of acetabulum and proximal femur component. Geomagic and 3ds max software according to the original three-dimensional laser scanner point cloud file can accurately perform reconstruction of hip surface replacement prosthesis, and provide a technical support for virtual surgery and personalized prosthesis design.
