<p>The invention relates to a joint prosthesis comprising a first part (1) with a cylindrical socket (6) and a second part (2) with a cylindrical head (8). The cylindrical head (8) and socket (6) are of complementary form, in such a manner that together they are able to form a linear hinge. The cylindrical socket (6) extends over at most 180° in the circumferential direction. The cylindrical head (8) is provided with a radial thickened section (9) which extends in the circumferential direction. The cylindrical socket (6) is provided with a radial recess (7) which extends in the circumferential direction and in which the radial thickened section (9) can be accommodated, with the cylindrical head (8) in bearing contact inside the cylindrical socket (6). The radial thickened section (9) and radial recess (7) are arranged centrally and are formed so as to be self-aligning with respect to one another. The cylindrical head (8) may be arranged on at least one support arm (10) and one or both longitudinal edges (21) of the cylindrical socket (6) may be provided, in the area of the at least one support arm (10), with a cutout (17) in which the support arm (10) can be completely or partially accommodated.</p> |
