Abstract
A prosthetic device includes one or more components configured to be disposed in a joint. The component includes at least one feature configured to provide information about the component. The information can be used to determine or create the relationship between the component and the joint and/or other components. This relationship may be used to evaluate and/or modify the expected performance of the prosthetic device and assist in determining the optimal relationship between one or more components and a patient's anatomy.
Claims13
A method comprising the steps of:
- identifying a positioning feature on a first implant implanted in a joint relative to a bone of the joint, wherein the positioning feature is a geometrical feature on the first implant configured to be contacted by a trackable probe and is configured to provide information representative of a positioning of the first implant;
- providing a trackable probe independent from the first implant;
- identifying at least one correspondence point on the bone;
- determining a desired geometric relationship between the first implant and the at least one correspondence point on the bone;
- determining an actual geometric relationship between the first implant implanted in the joint and the at least one correspondence point on the bone, wherein the actual geometric relationship is determined by:
- after the first implant is implanted in the joint, contacting the positioning feature on the first implant implanted in the joint with the trackable probe;
- acquiring, using a computing device, first information representative of the positioning of the first implant from the positioning feature on the first implant by tracking the trackable probe and second information about the bone from the at least one correspondence point on the bone,
- wherein the actual geometric relationship is based at least in part on the first information acquired about the first implant and the second information acquired about the bone;
- and
- adjusting a position and orientation of the first implant in the joint to achieve the desired geometric relationship.
