摘要：
Devices and processes for use in computer aided or computer navigated surgeryinclude frame attachments and indicia which can by easily manufactured at relativelylow cost comprising a single piece of injection molded plastic, are disposable,and which are manufactured for single use are disclosed. A fault interface canbe interposed between the indicia and an item to be used during surgery such asa body part, tool, implant, trial or other structure or component. After the indiciahave been registered into the system and surgery begun, it is sometimes the casethat indicia can be inadvertently moved or dislodged in position and / or orientationrelative to the body part. Fault interfaces according to various embodimentsare designed to fail first, so that the indicia can be repositioned relative tothe item without the need to reregister the indicia into the system relative tothe item. The fault interfaces preferably include structure that allows theindicium to be repositioned relative to the item so that it does not need to be reregisteredinto the system.
