Orthopedic surgery planning system

A method of operating an orthopedic surgery planning system, the method comprising:

• importing at least one medical image into a memory of a computer system;
• generating an anatomical structure 3D model of at least one anatomical structure, based on the at least one medical image and on a parameter that comprises one of a value or a set of density values of the at least one anatomical structure, using an extraction of a polygonal mesh of an isosurface from a three-dimensional scalar field comprising a plurality of voxels, said 3D model being a matricial volumetric image comprising a plurality of arrays of voxels;
• segmenting the anatomical structure 3D model based on the parameter;
• accessing a 3D prosthetic material model database to select at least one prosthetic material 3D model, said prosthetic material 3D model being a vectorial image comprising a set of geometric representations;
• combining a plurality of models derived from a plurality of structurally different images, by intersecting the anatomical structure 3D model and the 3D prosthetic material model;
• allowing a user to interact via a user interface with the anatomical structure 3D model and the 3D prosthetic material model, in a 2D environment area and in a 3D environment area, the anatomical structure 3D model and the 3D prosthetic material model being updated in real time in the 2D and 3D environments areas, wherein the 2D environment area comprises an axial 2D plan, a coronal 2D plan, and a sagittal 2D plan;
• identifying a suitable prosthetic material by performing the following steps one or more times:
• inserting into the anatomical structure 3D model at least one second anatomical structure different from the at least one anatomical structure, by segmenting said anatomical structure 3D model based on the parameter;
• simulating an implantation of a prosthetic material into the anatomical structure 3D model;
• and
• evaluating a suitability of the prosthetic material based on a predicted impact that a current planning might have on one or more surrounding structures and one or more predicted complications resulting from a surgery;
• generating, by a processor, a report comprising information relating to the planning performed and the steps performed to identify a suitable prosthetic material;
• and
• saving the information in the memory.
