Abstract
The present disclosure relates to devices and methods for verifying compatibility between cooperating parts of a joint prosthesis. The compatibility between the cooperating parts is with respect to at least one articulation parameter.
Claims20
A method for verifying compatibility between a first part and a second part of a joint prosthesis, with respect to at least one articulation parameter, the method comprising:
- providing or receiving at least one two-dimensional reference template defining at least one verification plane and obtained on a basis of the first part, one or more constraints relating to the second part, and the at least one articulation parameter, the reference template comprising an alignment reference and one or more boundaries;
- providing or receiving a two-dimensional prosthesis template corresponding to a shape of the second part, as viewed in the at least one verification plane;
- aligning the prosthesis template with the at least one reference template by superimposing the two templates and aligning the prosthesis template to the reference template using the alignment reference;
- and
- considering the second part as compatible with the first part if the shape of the second part lies within the one or more boundaries of the at least one reference template, when the at least one reference template and the prosthesis template are aligned.
A device for verifying compatibility between a first part and a second part of a joint prosthesis, comprising:
- at least one two-dimensional reference template defining at least one verification plane and obtained on a basis of the first part, constraints relating to the second part, and the articulation parameter,
- the at least one reference template comprising a boundary and an alignment reference configured to align the at least one reference template with a two-dimensional prosthesis template having a shape of the second part, as viewed in the at least one verification plane.
A method for producing a device for verifying compatibility between a first part and a second part of a joint prosthesis, with respect to at least one articulation parameter, the method comprising:
- providing or obtaining a two-dimensional reference template defining a verification plane, the reference template obtained on a basis of the first part, constraints relating to the second part, and to the articulation parameter;
- and
- providing or obtaining the reference template with one or more reference boundaries and an alignment reference for aligning the reference template with a two-dimensional prosthesis template having the shape of the second part as viewed in the first verification plane.
