A method of planning a procedure to fasten an implant (10) to a bone (70) includes displaying a model of the bone (70) and a model of the implant (10) on a display device (110). The model implant (10) is positioned on the model bone (70) in a desired implant position. A first boundary volume (52A-C) of a first fastener (50) configured to fasten the prosthesis (10) to the bone (70) is also displayed on the display device (110). The first boundary volume (52A-C) represents a range of possible positions that the first fastener (50) may have with respect to the prosthesis (10) when fastened to the bone (70). The boundary volume (52A-C) may be used to determine a desired size, shape, and/or positioning of the fastener (50) with respect to the bone (70).
