Abstract:
A modular system including a mounting apparatus for the mounting of shaft prostheses, the modular system comprising:shaft prostheses that are assembled from stems of different sizes and prosthesis heads of different sizes, wherein each shaft prosthesis includes a fixable coupling between its respective stem and its respective prosthesis head, the fixable coupling allowing for different positions and angular orientations between the prosthesis head and the stem; andtest prostheses that are assembled in different sizes analogously to the shaft prostheses, each test prosthesis including a releasably fixable coupling that is fixed in the test prosthesis, wherein a test prosthesis that is inserted in a bone holds an ideal position and angular orientation of a head of the test prosthesis with respect to a stem of the test prosthesis;wherein after removal of a test prosthesis, the ideal position and angular orientation of the head of the test prosthesis with respect to the stem is transmitted with the test prosthesis to the mounting apparatus in order to mutually fix a stem and prosthesis head corresponding to the test prosthesis in the position and angular orientation in the test prosthesis in the mounting apparatus.
