Abstract:
A template for use in matching parts of a modular joint prosthesis component to an image of a bone in which the prosthesis component is to be implanted, the prosthesis component comprising a first part and a second part which are fitted together to assemble the prosthesis component for implantation, which comprises:a. a first template part which bears an image of the first part of the prosthesis component, and b. a second template part which bears images of a plurality of the second parts of the prosthesis component, each of the second parts being a sleeve having a through bore in which, in the assembled prosthesis component, the first part of the prosthesis component can be received, in which 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 of the prosthesis component are aligned sequentially in relation to the image of the first template part to form a composite image of the prosthesis component, one of the template parts overlying the other of the template parts and being transparent so that the image on the said other template part is visible through the overlying template part when the images on the template parts are aligned.
