A computer-implemented bone-implant system evaluation method for application of mesh-free analysis of a bone-implant system for evaluation of performance of a bone-implant system for an implant implanted within the bone structure at an anatomical site, said method comprising: (i) receiving a set of bone structure data set , wherein set of bone structure data includes data indicative of the bone structure at an anatomical site; (ii) inputting an implant data set and inputting the position of the implant data set , wherein the implant is selected based upon the biomechanical requirements for the anatomical site and the position and of the implant data set is indicative of the position of the implant with respect to the anatomical site, wherein implant data set includes data representative of the geometry and materials properties of the implant; (iii) creating a bone-implant model , wherein said bone implant-model includes a mesh-free model of trabecular bone at the anatomical site wherein the bone-implant model is formed from the bone structure data set from step (i), wherein said mesh-free model includes a plurality of nodes which represents said trabecular bone at the anatomical site, and wherein said plurality of nodes are free to interact with any neighboring nodes they may come into contact with in the mesh-free model, and the implant data set from step (ii), and wherein the mesh-free model of trabecular bone is indicative of the trabecular bone structure of the bone structure at the anatomical site; and (iv) determining a biomechanical result based upon computer simulated loading of the bone-implant system based upon mesh-free analysis 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. (i) receiving a set of bone structure data set , wherein set of bone structure data includes data indicative of the bone structure at an anatomical site; (ii) inputting an implant data set and inputting the position of the implant data set , wherein the implant is selected based upon the biomechanical requirements for the anatomical site and the position and of the implant data set is indicative of the position of the implant with respect to the anatomical site, wherein implant data set includes data representative of the geometry and materials properties of the implant; (iii) creating a bone-implant model , wherein said bone implant-model includes a mesh-free model of trabecular bone at the anatomical site wherein the bone-implant model is formed from the bone structure data set from step (i), wherein said mesh-free model includes a plurality of nodes which represents said trabecular bone at the anatomical site, and wherein said plurality of nodes are free to interact with any neighboring nodes they may come into contact with in the mesh-free model, and the implant data set from step (ii), and wherein the mesh-free model of trabecular bone is indicative of the trabecular bone structure of the bone structure at the anatomical site; and (iv) determining a biomechanical result based upon computer simulated loading of the bone-implant system based upon mesh-free analysis 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. <EOS>
