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: &#x2014;determining the geometric shape of the joint socket, in particular the acetabulum, and the geometric shape of the cup which is to be placed; &#x2014;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; &#x2014;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; &#x2014;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: &#x2014;defining at least one requirement for the position and/or orientation of the cup; &#x2014;calculating an optimum position and/or orientation of the cup on the basis of all the defined requirements being fulfilled.

Method for planning positioning of a ball joint prosthesis

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: &#x2014;determining the position of at least one point lying on the rim of the joint socket, in particular the position of at least two points lying in an anterior region of the acetabulum; &#x2014;defining a requirement for the position and/or orientation of the cup on the basis of the determined positions of the at least one point. 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: &#x2014;defining at least one requirement for the position and/or orientation of the cup; &#x2014;calculating an optimum position and/or orientation of the cup on the basis of all the defined requirements being fulfilled.

A patient lateral positioning device for pelvic treatments suitable to support a patient in a defined lateral position includes a vacuum mattress. The vacuum mattress includes an upper body support attachable to an upper body portion of the patient, and a lower body support attachable to a lower body portion of the patient. A region between said upper and lower body support is formed such that when the vacuum mattress is attached to the patient, both a front pelvic side and an upper pelvic side of the patient are exposed.
