摘要:
An artificial bone template selection system includes a template data storage system in which template data representing a plurality of templates representing a plurality of artificial bones of different shapes is stored. A bone shape measuring system measures the shape of bone to be replaced by artificial bone on the basis of bone image data representing an image including the bone to be replaced by artificial bone. A prospective template selection system selects at least one template the shape of which substantially conforms to the shape of the bone to be replaced by artificial bone as measured by the bone shape measuring system out of the plurality of templates represented by the template data.
摘要:
The present invention provides a method and a device for producing an orthosis model for a patient. The method comprises the input of patients' data (104), the determination (106) of a curvature type of the patient's spine to be treated from a predefined number of curvature types in dependence on the patient's data, and the selection (110) of at least one orthosis model from a predefined number of models of orthoses in dependence on the specific curvature type. The device comprises a data input device (6) being designed for inputting patients' data, a data base (12) containing a number of curvature types and a number of orthoses models, a curvature determination device (8) designed to determine a curvature type from the data base in dependence on the patients' data, and an orthosis model selection device (10) designed to select at least one orthosis model from the data base in dependence on the determined curvature type.
摘要:
A method for constructive modelling of articles including prostheses and anatomical pathology wherein CT scan data is computed to construct a plurality of two dimensional cross sectional images along one axis and the two dimensional image data is computed to create three dimensional coordinate data sets for the articles to be modelled. The three dimensional data sets are then computed to obtained spaced parallel two dimensional image data sets in a second plane of the article and the reconstructed two dimensional image data sets are employed in a constructive modelling process to produce a three dimensional model of the article or part thereof.
摘要:
An improved orthopedic joint prosthesis (10) has a prosthesis body (14) having a first surface (17) for engaging a patient's joint and a second surface (16) for receiving a polymeric liner (15). The second surface (16) is highly polished or mirror-like, for retarding debris generating from the polymer liner (15) and also allows optical pattern inspection.

摘要:
A computer-implemented method of planning orthopaedic surgery comprises providing a library of templates representing orthopaedic prostheses, displaying and scaling one or more patient images such as X-ray images, allowing a user to reconfigure geometrical constructs displayed over the images to match the construct to anatomical features shown in the image; and selecting one or more templates from the library in accordance with parameters of the reconfigured constructs. The templates correspond to the orthopaedic prosthesis or prostheses which are most suitable for the patient. Hip replacement surgery can be planned using a single patient image. Knee surgery can be planned using two patient images showing different views of the anatomical features, in which case geometrical constructs for use with each view are provided. The library of templates is accessible via the Internet so as to be accessible by users in any location and readily updateable.
摘要:
A template for use in matching parts (6, 8) of a modular joint prosthesis component to an image of a bone in which the prosthesis component is to be implanted, the prosthesis component including first and second parts (6, 8) which are fitted together to assemble the prosthesis component for implantation. The template comprises a first template part which bears an image of the first part of the prosthesis component, and a second template part which bears images of a plurality of the second parts (23) of the prosthesis component, each of the second parts (23) being a sleeve having a through bore in which, in the assembled prosthesis component, the first part (6) of the prosthesis component can be received. The second template part is connected to the first template part but can be moved relative to it so that the images of the second parts (23) of the prosthesis component can be aligned sequentially in relation to the image of the first template part (6) to form a composite image of the prosthesis component.
