Abstract:
1. A method for (i) determining the orientation of a first joint prosthesis vis-à-vis a second, mating joint prosthesis, and (ii) adjusting the orientation of the first joint prosthesis vis-à-vis the second, mating joint prosthesis when appropriate, the method comprising the steps of: providing a database comprising a plurality of different pre-determined data sets, wherein each of the plurality of different pre-determined data sets correlates to a range of motion permitted between the first joint prosthesis and the second, mating joint prosthesis when the first joint prosthesis and the second, mating joint prosthesis have a particular spatial relationship vis-à-vis one another; moving the second, mating joint prosthesis while in engagement with the first joint prosthesis so as to generate an actual data set which correlates to a range of motion permitted between the first joint prosthesis and the second, mating joint prosthesis given the actual spatial relationship between the first joint prosthesis and the second joint prosthesis; comparing the actual data set with the plurality of different pre-determined data sets in the database so as to identify the actual orientation of the first joint prosthesis vis-à-vis the second, mating joint prosthesis; and adjusting the actual orientation of the first joint prosthesis vis-à-vis the second, mating joint prosthesis when appropriate using a device mounted to the second, mating joint prosthesis.
