Abstract
The present invention relates to a method for planning the positioning of a ball joint prosthesis, in particular a hip joint prosthesis, wherein the prosthesis includes a stem and a cup and the method comprises the following steps: —determining the geometric shape of the joint socket, in particular the acetabulum, and the geometric shape of the cup which is to be placed; —defining target areas where the cup has to abut the bony structure of the joint socket, in particular the acetabulum, in order for the cup to be sufficiently fixed; —determining actual areas of the cup which will abut the bony structure of the joint socket, in particular the acetabulum, when the cup is placed; —defining a requirement for the position and/or orientation of the cup on the basis of the position and/or size of the target areas and/or actual areas. The present invention also relates to a method for optimizing the positioning of a ball joint prosthesis, in particular a hip joint prosthesis, wherein the prosthesis includes a stem and a cup and the method comprises the following steps: —defining at least one requirement for the position and/or orientation of the cup; —calculating an optimum position and/or orientation of the cup on the basis of all the defined requirements being fulfilled.
