摘要： A custom arthroplasty guide and a method of manufacturing such a guide are disclosed herein. The guide manufactured includes a mating region configured to matingly receive a portion of a patient bone associated with an arthroplasty procedure for which the custom arthroplasty guide is to be employed. The mating region includes a surface contour that is generally a negative of a surface contour of the portion of the patient bone. The surface contour of the mating region is configured to mate with the surface contour of the portion of the patient bone in a generally matching or interdigitating manner when the portion of the patient bone is matingly received by the mating region. The method of manufacturing the custom arthroplasty guide includes: a) generating medical imaging slices of the portion of the patient bone; b) identifying landmarks on bone boundaries in the medical imaging slices; c) providing model data including image data associated with a bone other than the patient bone; d) adjusting the model data to match the landmarks; e) using the adjusted model data to generate a three dimensional computer model of the portion of the patient bone; f) using the three dimensional computer model to generate design data associated with the custom arthroplasty guide; and g) using the design data in manufacturing the custom arthroplasty guide.

摘要： Methods are provided for transmitting and navigating interlinked data using an interactive programming system. Pages of interlinked data are encoded at a network node, and data navigation information is generated for each page of the interlinked data. This data is then stored at the node. A user at a subscriber location, connected to the node by a television signal distribution network, is able to view a first page of the interlinked data, provided by the interactive programming system to the user's settop for display on a display device. The interactive programming system also provides the data navigation information to the user's settop. The interpreter within the user's settop creates a chaser, which is displayed at one of the links of the interlinked data and allows the user to navigate those links. The user may use the chaser to select a link, which is interpreted within the settop to provide a command signal identifying an action, such as sending another page of the data to the user's settop.
