PROBLEM TO BE SOLVED: To provide surgical navigation system component fault interfaces and related processes.SOLUTION: Disclosed are devices and processes for use in computer-aided or computer-navigated surgery including a frame attachment and indicium which include a single plastic component, can be easily manufactured at relatively low cost, are disposable, and which are manufactured for single used. Fault interfaces can be interposed between an indicium and an item to be used during surgery such as a body part, tool, implant, trial or other structure or component. After the indicia have been registered into the system and surgery begun, it is sometimes the case that indicia can be inadvertently moved or dislodged in position and/or orientation relative to the body part. Fault interfaces are designed to fail first, so that the indicia can be repositioned relative to the item without the need to reregister the indicia into the system relative to the item. |
