Joint prosthesis and method of bone fixation

Abstract

The invention relates to a joint prosthesis (10), for example, a knee joint or shoulder joint prosthesis comprising a first, socket-holding prosthesis part (11) for attachment to a first bone (12) and a second, ball-holding prosthesis part (13) for attachment to a second bone (14) that intermates with the first prosthesis part, wherein the first bone and the second bone are situated at either side of a joint, and wherein the ball (2) of the second prosthesis part is rotatably received in the socket (5) of the first prosthesis part, wherein the first prosthesis part can be coupled with the first bone by applying tensile strain bearing rods (6), wherein when the mounted prosthesis is in a virtually unloaded condition, there is no significant tensile force in the rods.Aerospace Engineerin
