Abstract
A method for planning a bone implant ascertains a condition of a bone to be treated, and identifies a dysfunctional part of the bone. A free-form area then can be ascertained and registered, wherein the free-form area lies below the dysfunctional part. A control data set then is produced that forms the basis for ablating the bone on the ascertained free-form area.
Claims21
A method for planning a bone implant, comprising:
- obtaining image data corresponding to a bone to be treated;
- identifying in the image data a dysfunctional part of the bone and a functional part of the bone;
- ascertaining a contour of an interface between the dysfunctional part of the bone and the functional part of the bone;
- registering the ascertained contour in a medical navigation system, wherein registering the contour includes registering the contour a predetermined distance below the interface;
- using a processor to produce a control data set based on the registered contour of the interface, said control data set forming the basis for ablating the bone;
- and
- outputting the control data set.
4 more elements
A system for modifying a bone and/or bone implant, comprising:
- a processor and memory;
- logic stored in memory and executable by the processor, said logic comprising
- logic that receives information corresponding to a contour of an interface between a dysfunctional part of the bone and a functional part of the bone;
- logic that registers the contour in a medical workspace, wherein the logic that registers the contour includes logic that registers the contour a predetermined distance below the interface;
- logic that produces instructions for directing the ablation of a bone based on the registered contour;
- and
- a navigation-assisted bone ablating device operative to implement the instructions to ablate the bone.
