摘要： The invention provides a prosthesis structure for anchorage to the joint end of an articulatory part of a joint in a human or animal body which comprises an engagement element which presents a flat or a substantially flat engagement surface for engaging with a complementary joint end surface provided at the joint end and an elongate fixture connected to and spaced from the engagement surface for insertion into a complementary bore provided at the joint end at a distance from the joint end surface. The invention further provides that the elongate fixture forms an acute angle with the engagement surface.

摘要： The invention relates to a cutting guide instrument and method for enabling high-precision resection of the head (caput femoris) (8) of the neck (5) of a human femur (collum femoris) at a predetermined cutting angle (&agr;c) to the femoral shaft (9) and on a predetermined cutting level (Lc) with respect to the proximal end of the caput (8). A support part (11) is fixed to the femur during the resection. A longitudinal guide carrier (12) is supported by the support part (11) and is aligned along the femoral collum (5) at said predetermined cutting angle (&agr;c) to the femoral shaft (9). A cutting guide (13) is supported by and movable along the axis (D—D) of the guide carrier (12) to a cutting position corresponding to the predetermined cutting level (Lc). The invention also relates to the use of the instrument for performing such resection.

摘要： The invention is directed to a reamer for shaping a bone socket such as an acetabular cavity. The reamer comprises a cutting head for removing material from the socket during rotation of the cutting head. The cutting head comprises a number of relatively long main cutting edges, each of which extends in a direction from a base to a top of the reamer, and a number, higher than the number of main cutting edges, of relatively short peripheral cutting edges, which are located at the base and distributed at angulary spaced intervals about a rotational axis. The invention also provides a method for implanting a prosthesis component into a bone socket. During shaping of the bone socket, a top portion of the reamer is completely received in the bone socket to such an extent, that a cylindrical entrance portion is formed in the socket. The invention also provides a kit including a reamer and a prosthesis.

摘要： The invention relates to a fixture for insertion into and permanent anchorage in a cavity (32) formed in bone tissue. The fixture is made of a fixture member (2), which has an insertion end surface (10) and a cylindrical peripheral surface (6) provided with screw threads, and a plurality of circumferentially-spaced cutting recesses (9), which are formed in a forward, self-tapping end portion (7) of the threaded peripheral surface (6) adjacent to the insertion end surface (10) and which open axially into the insertion end surface (10). A plurality of circumferentially-spaced tissue-collecting and tissue-distributing grooves (17) are formed in a rear, non-self-tapping portion (8) of the threaded peripheral surface (6). The grooves (17) open radially outwards and extend at least partially in the longitudinal direction of the fixture member (2), and each groove (17) is, at a forward end thereof, connected to one of the cutting recesses (9) for collecting cut-off bone material (B) circumferentially around the inner wall of the cavity (32) during the insertion of the fixture.
摘要翻译：本发明涉及一种用于插入并固定在形成于骨组织中的空腔（32）中的固定器。夹具由具有插入端面（10）和设置有螺纹的圆柱形周面（6）的固定构件（2）和多个周向间隔开的切割凹部（9）形成，在与所述插入端表面（10）相邻并且轴向地插入所述插入端表面（10）中的所述螺纹周边表面（6）的前进自攻端部（7）中。多个周向间隔开的组织收集和组织分配槽（17）形成在螺纹周边表面（6）的后非自攻螺纹部分（8）中。凹槽（17）径向向外开放并且至少部分地沿着固定构件（2）的纵向方向延伸，并且每个凹槽（17）在其前端处连接到一个切割凹槽（9），用于在插入固定装置期间周向地围绕空腔（32）的内壁收集切断骨材料（B）。
