Abstract:
1. A method for locating during a surgical procedure a mechanical axis of an uncut bone having an end with an external surface, comprising the steps of: (a) generating an image of the uncut bone including the external surface; (b) defining the mechanical axis of the uncut bone on the image of the uncut bone; (c) measuring an angle between the mechanical axis of the uncut bone as defined in step (b) and a reference axis on the image of the uncut bone, the reference axis containing at least two reference points located on the image of the external surface of the uncut bone; (d) during surgery, contacting at least two points on the external surface of the uncut bone with a first plate, the first plate being fastened to an angle indicator, the angle indicator being pivotably fastened to an axis indicator, at least one of the axis indicator and the angle indicator including a scale to indicate an angle between the angle indicator and the axis indicator; and (e) positioning the axis indicator relative to the angle indicator such that the angle indicated on the scale has a predetermined relationship with the angle measured in step (c).
