DETERMINING A POSITION FOR AN IMPLANT RELATIVE TO A BONE BASED ON BONE REMODELING DATA
A computer-assisted method is provided for determining a placement position for an implant relative to a bone. According to the method, a force profile exerted on a bone is calculated from bone density data and bone architecture data. A position and orientation (POSE) for an implant in relation to the bone based is then determined, at least in part, on the calculated force profile. A computing system is provided that includes a computer having a processor and non-transient memory programmed with operating planning software that when executed by the processor is configured to: calculate a force profile exerted on a bone from bone density data and bone architecture data and determine a position and orientation (POSE) for an implant in relation to the bone based, at least in part, on the calculated force profile.
1 . A computer-assisted method for determining a placement position for an implant relative to a bone, said method comprising:
calculating a force profile exerted on a bone from bone density data and bone architecture data; and
determining a position and orientation (POSE) for an implant in relation to the bone based, at least in part, on the calculated force profile.
2 . The method of claim 1 wherein the bone density data and bone architecture data is obtained from computed tomography (CT) or magnetic resonance imaging (MRI).
3 . The method of claim 1 wherein the force profile is calculated using at least one of finite element analysis or machine learning.
4 . The method of claim 1 wherein the force profile is displayed via a graphical user interface (GUI).
5 . The method of claim 4 wherein the force profile is displayed as one of a series of lines, a heat map, a matrix of values, or other graphical technique on a bone model.
6 . The method of claim 1 wherein the force profile is viewed in two-dimensions (2-D) or three-dimensions (3-D) on a bone model.
7 . The method of claim 1 wherein the force profile indicates how the bone remodeled under loading conditions for a joint and is indicative of a natural motion of the joint.
8 . The method of claim 1 wherein the joint is one of a hip, knee, shoulder, or elbow.
9 . The method of claim 1 wherein the determining of the position and orientation for the implant in relation to the bone comprises receiving computer input from a user to adjust a position or orientation of the implant in relation to the bone.
10 . The method of claim 1 wherein the determining of the position and orientation for the implant in relation to the bone comprises determining a POSE for implant image data in relation to bone data.

calculate a force profile exerted on a bone from bone density data and bone architecture data; and
determine a position and orientation (POSE) for an implant in relation to the bone based, at least in part, on the calculated force profile.
12 . The system of claim 11 further comprising a graphical user interface (GUI).
13 . The system of claim 12 wherein the GUI displays the calculated force profile with respect to bone data of the bone.
14 . The system of claim 11 wherein the non-transient memory further stores implant image data for a plurality of different implants.
