Claim 11:
12. A system for computer-implemented bone-implant system evaluation for evaluation of performance of a bone-implant system for an implant implanted within the bone structure of a subject at an anatomical site using mesh-free analysis of trabecular bone of a bone-implant system, the system comprising:
an implant data set input interface,
a bone structure data input module,
a processor in communication with the bone structure data input module and in communication with the implant data set input interface, and
a data output module in communication with the processor, wherein
the system is configured to use a bone-implant model including a mesh-free trabecular bone model which comprises a plurality of bone data nodes which represents trabecular bone and comprises material properties of trabecular bone wherein bone data nodes of plurality of bone data nodes are free to interact with any neighboring bone data nodes of said plurality of bone data nodes upon contact with said neighboring bone data nodes and wherein said bone data nodes are broken off, moved, and redistributed from neighboring bone data nodes within the mesh-free trabecular bone model upon computer simulated loading of the bone-implant system, wherein the redistribution of bone data nodes is representative of fragmentation and redistribution of trabecular bone;
the bone structure data input module is configured to receive at least one set of bone structure data, wherein set of subject data comprises data indicative of the bone structure and wherein the bone structure comprises trabecular bone, of the subject at an anatomical site;
the implant data module is configured to receive at least one implant data set and receives data indicative of the position of the implant with respect to the anatomical site, wherein the implant is based upon the biomechanical requirements for the anatomical site, and wherein implant data set comprises data representative of the geometry and materials properties of the implant;
the processor is configured to receive bone structure data from the bone structure data input module and receives implant data from the implant data input interface, and
wherein the processor is configured to create a bone-implant model wherein said bone implant-model comprises a mesh-free trabecular bone model representative of said trabecular bone at the anatomical site, wherein the bone-implant model is formed from the at least one bone structure data set from and from the at least one implant data set, and wherein the mesh-free trabecular bone model of trabecular bone is indicative of the trabecular bone structure of the bone structure at the anatomical site and which comprises material properties of said trabecular bone, wherein said mesh-free trabecular bone model is an analytical model which comprises a plurality of bone data nodes which represents said trabecular bone at the anatomical site, and wherein bone data nodes of said plurality of bone data nodes of said mesh-free trabecular model are free to interact with any neighboring bone data nodes of said plurality of bone data nodes upon contact with said neighboring bone data nodes, wherein said bone data nodes are broken off, moved, and redistributed from neighboring bone data nodes within the mesh-free trabecular bone model upon simulated physiological loading of the bone-implant system, wherein the redistribution of bone data nodes is representative of fragmentation and redistribution of trabecular bone;
wherein the processor is configured to provide output data to the output module, wherein the output data comprises a biomechanical result based upon said simulated physiological loading of the bone-implant system based upon mesh-free analysis by utilization of a mesh free analytical method, of the bone-implant model, wherein the biomechanical result includes data based on the displacement of the implant relative to the bone of bone-implant model; and
wherein the processor is configured to repeat automatically, i) receipt of the at least one implant data set and data indicative of the position of the implant with respect to the anatomical site by the implant data module, ii) creation of the bone implant model, and iii) determination of the biomechanical result, until a requisite implant data set is determined and a preferable implant positioning is obtained which provides said biomechanical requirements based on redefined parameters, and wherein upon the requisite implant data set being determined, an implant recommendation report is provided, wherein said implant recommendation report includes one or more of implant type, implant size, implant configuration, implant positioning, and combinations thereof.
