Abstract
Computer implemented systems and methods for removing bone cement or other material to replace a bone prosthesis is provided. A computer aided method of replacing a bone prosthesis according to the present invention comprises the steps of: receiving as input image data of a bone; identifying bounding contours of material in the image data surrounding a first bone prosthesis for removal; and generating system contours from the bounding contours, the system contours specifying a cavity to be cut in the bone to accommodate a second bone prosthesis.
Claims12
A method for producing a cut file useful for controlling a robotic system for replacing a bone prosthesis, said method comprising the steps of:
- receiving image data comprising an image of a bone;
- identifying bounding contours of a non-bone material surrounding a first bone prosthesis to be removed in the image data;
- generating system contours from the bounding contours, the system contours specifying a cavity to be cut in the bone to accommodate a second bone prosthesis;
- generating a cut file from the system contours for use by the robotic system;
- and
- storing the cut file in a tangible medium.
A computer program product for replacing a bone prosthesis, comprising:
- computer readable code for receiving image data of a bone;
- computer readable code for identifying bounding contours of a non-bone material in the image data, wherein said material surrounding a first bone prosthesis for removal;
- computer readable code for generating system contours from the bounding contours, the system contours specifying a cavity to be cut in the bone to accommodate a second bone prosthesis;
- computer readable code for generating a cut file from the system contours;
- and
- a tangible medium for storing the computer readable codes.
