Abstract
An artificial joint designed in particular to replace human joints, consisting of at least two joint sections (21, 22) with mutually movable spherical functional surfaces. The ratios of curvature of the functional surfaces (23, 24) with a circular cutting contour are convex-convex, convex-concave or concave-concave and the joint geometry is determined by a joint chain with two joint axes which run through the centres of rotation M1? and M2? of the functional surfaces with the radii R1? and R2?. R1? is the radius of the circular cutting contour of the functional surface with the centre point M1? and R2? is that of the circular cutting contour of the functional surface with the centre point M2?. Between the two functional surfaces (23, 24) of the joint sections (21, 22) there is a compression distribution component (25) whose sliding surfaces (26, 27) bearing on the functional surfaces have a curvature matched to one of the functional surfaces, the sliding surfaces (26, 27) of the compression distribution component (25) being of approximately the same size.
