  • Ankle-Joint Endoprosthesis
    Publication number: 20140081413
    Abstract: An endoprosthesis for replacing the ankle joint includes a lower component which is configured to be connected to the ankle bone, an upper component which is configured to be connected to the shin bone, and an intermediate part which forms a slide joint both with the lower and upper components. The intermediate part, which is wedge-shaped in sagittal section, is provided in order to compensate for anatomical or surgical irregularities. The upper component can also be wedge-shaped in frontal or sagittal section.

  • ENDOPROSTHESIS WITH INTERMEDIATE PART
    Publication number: 20100204799
    Abstract: An endoprosthesis for replacement of a joint includes two slide surfaces having different contours and correspondingly determining movement planes for a bearing formed by an intermediate part. The endoprosthesis includes a clamping bracket to enclose the slide surfaces of the intermediate part that is arranged thereon such that it is free from the movement planes defined by the slide surfaces having different contours. It is thus possible to strengthen endoprostheses which have complex biomechanics having a plurality of degrees of freedom.
