Abstract
A method for designing a patient specific orthopaedic device intended for an osteoarticular structure of a patient, based on at least two two-dimensional radiographic images of the osteoarticular structure taken respectively in two offset image-taking directions, comprising the following steps: b) locating anatomical points on the radiographic images; c) determining at least one three-dimensional geometrical feature of the patient by matching the anatomical points b) located at step b); d) determining at least one three-dimensional size parameter of the orthopaedic device based on the geometrical feature of the patient determined at step c).

A method for designing a patient specific orthopaedic device intended for an osteoarticular structure of a patient, based on at least two two-dimensional radiographic images of the osteoarticular structure taken respectively in two offset image-taking directions, comprising the following steps:
- b) locating anatomical points on the radiographic images;
- c) determining at least one three-dimensional geometrical feature of the patient by matching the anatomical points located at step b);
- d) determining at least one three-dimensional size parameter of the orthopaedic device based on the geometrical feature of the patient determined at step c).
An apparatus for designing a patient specific orthopaedic device intended for an osteoarticular structure of a patient, based on at least two two-dimensional radiographic images of the osteoarticular structure taken respectively in two offset image-taking directions, comprising:
- means for locating anatomical points on the radiographic images;
- means for determining at least one three-dimensional geometrical feature of the patient by matching the anatomical points located by the locating means;
- means for determining at least one three-dimensional size parameter of the orthopaedic device based on the geometrical feature of the patient determined by the determining means.
