Abstract
A method of designing an orthopedic implant comprising: (a) iteratively evaluating possible shapes of a dynamic orthopedic implant using actual anatomical shape considerations and kinematic shape considerations; and, (b) selecting a dynamic orthopedic implant shape from one of the possible shapes, where the dynamic orthopedic implant shape selected satisfies predetermined kinematic and anatomical constraints.
Claims22
A method of preparing a joint for a joint replacement implant, the method comprising:
- fixing a first bone tracker to a first bone, the first bone tracker providing data associated with at least one of a position of the first bone and an orientation of the first bone from a first bone tracker inertial measurement unit;
- registering the first tracker to the first bone;
- fixing a second bone tracker to a second bone, the second bone tracker providing data associated with at least one of a position of the second bone and an orientation of the second bone from a second bone tracker inertial measurement unit;
- registering the second bone tracker to the second bone;
- attaching a first cutting guide to at least one of the first bone and the second bone;
- cutting one of the first bone and second bone using the first cutting guide;
- attaching a second cutting guide to at least one of the first bone and the second bone;
- and
- cutting the other of the first bone and the second bone using the second cutting guide;
- wherein the first bone and the second bone are associated with a joint;
- wherein attaching the first cutting guide comprises attaching the first cutting guide to the first bone;
- wherein cutting the one of the first bone and the second bone using the first cutting guide comprises cutting the second bone;
- wherein attaching the second cutting guide comprises attaching the second cutting guide to the first bone;
- and
- wherein cutting the other of the first bone and the second bone using the second cutting guide comprises cutting the first bone.
