  • Publication number: 20140018930
    Abstract: A prosthesis for primary artrodhesis can be used for artroplasty and a prosthesis for artroplasty comprises members for artrodhesis. The prosthesis (1b) for primary artrodhesis comprises a locking member (33b) with an attachment portion (16b) which is insertable into a hole (8b) in a first attachment member (4b) of the prosthesis for location of the locking member therein, and a lockable member (34b) integral with a second attachment member (5b) of the prosthesis. The lockable member (34b) is configured for adjustable setting thereof relative to the locking member (33b) and for fixation thereof, in set position, to the locking member. Alternatively, the lockable member comprises an attachment portion which is insertable into a hole in the second attachment member for location of the lockable member therein.

  • Publication number: 20110112652
    Abstract: The present invention relates to a joint prosthesis (1) comprising two prosthesis components (2, 3) intended to be applied respectively to the trapezium (38) and the first metacarpal bone (39) of a thumb joint, each prosthesis component having a first or second screw-like part (4, 5) intended to be screwed firmly or be fastened to one of said bones (38 or 39) by means of bone cement, the one prosthesis component (2) having an articulating socket element (6) and the other prosthesis component (3) an articulating ball element (7). The fact that at least the prosthesis component (2) with the socket element (6) has an abutment portion (20) for abutment against the bone to which the screw-like part (4) of the prosthesis component is intended to be firmly screwed or be fastened by means of bone cement, normally the trapezium (38), prevents this prosthesis component from sinking into said bone.

  • Patent number: 7837738
    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 (30 and 33 respectively) 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).

  • Publication number: 20080065224
    Abstract: The present invention relates to a joint prosthesis, comprising two prosthesis members (2, 3) which are adapted to be positioned at different bones (39, 41, 42) at a joint (38), wherein each prosthesis member (2, 3) includes a first and a second screw-like member (4, 5) respectively, which are adapted to be screwed onto the 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, whereby the socket member (6) has a mounting pin (22) which is insertable into a first hole (10) in the first screw-like member (4) for positioning or locating the socket member (6) thereto and whereby the head member (7) has a mounting pin (27) which is insertable into a first hole (11) in the second screw-like member (5) for positioning or locating said head member (7) thereto.
