ABSTRACT:
A joint prosthesis has two prosthesis members (2, 3) and each prosthesis member (2, 3) includes a first and a second screw-like member (4, 5) adapted to be screwed onto a respective bone (39, 41, 42). One prosthesis member (2) includes a member (6) having a socket and the other prosthesis member (3) a member (7) having a head. The socket member (6) has a mounting pin (22) insertable into a first hole (10) in the first screw-like member (4) and the head member (7) has a mounting pin (27) insertable into a first hole (11) in the second screw-like member (5). In the first as well as in the second screw-like member (4, 5) there is provided at least one inner second hole (30and33respectively) designed to permit insertion thereinto of a rod (31) of a screw tool (32) in order to secure by screwing the first and second screw-like member (4, 5) respectively, at the respective bone (39, 41, 42). The second hole (30and33respectively) is provided in a bottom (17and19respectively) of the first hole (10and11respectively).
