摘要： Provided is a joint replacement with a joint socket (10) having a concave joint surface (11), and with a joint insert (20) having a concave joint surface (21) and a convex joint surface (22) which are each delimited by a peripheral edge (23, 24). The convex joint surface (22) of the joint insert (20) is designed, in the assembled state, to form a first partial joint with the concave joint surface (11) of the joint socket (10). Moreover, the concave joint surface (21) of the joint insert (20) is designed, in the assembled state, to form a second partial joint with the convex joint surface (32) of a joint head (30). The joint socket (10) and the joint insert (20) each have a securing means (12, 25, 26) for preventing dislocation of the joint replacement.

摘要： An acetabular component anteversion and abduction measurement system, comprising: an acetabular component; one or more radiopaque guide lines disposed on or adjacent to a posterior surface of the acetabular component; and one or more radiopaque guide lines disposed on or adjacent to an anterior surface of the acetabular component; wherein predetermined alignment of selected of the one or more anterior guide lines with selected of the one or more posterior guide lines under intra-operative fluoroscopy or radiography indicates proper surgical alignment of the acetabular component within the anatomy of a patient. Proper surgical alignment means that the acetabular component is not retroverted or overly anteverted or abducted within the anatomy of the patient.

摘要： An acetabular hip implant includes an acetabular shell component having a first feature and a first insert having a second feature that cooperates with the first feature of the acetabular shell component and further includes a third feature. The implant further includes a second insert having a fourth feature that cooperates with the third feature of the first insert and further includes a fifth feature. A femoral head component includes a sixth feature that cooperates with the fifth feature. Interaction between the first and second features, between the third and fourth features, and between the fifth and sixth features mechanically constrains the acetabular hip implant to prevent dislocation of the femoral head during rotation.

摘要： A method for placing a prosthetic acetabular cup within an acetabulum comprises implanting an acetabular cup with an eccentric socket. The acetabular cup may be substantially hemispherical with a cup rim and a portion of the cup rim removed defining a relief. The cup may accommodate a concentric liner in an eccentric position. Screw apertures may be present on the periphery of the cup and the screw trajectories may converge toward the dome of the cup. The cup is attached to a tool which is offset relative to the cup because of the substantially eccentric socket. The relief, when the cup is secured to the acetabulum, is positioned substantially anterior and the socket is positioned more posterior to provide a more natural center of rotation of a femoral head within the socket. The first relief reduces impingement of the acetabular cup on soft tissue.

摘要： A prosthetic hip joint replacement system has a femoral component with a tapered trunion thereon. A modular head with a part-spherical outer surface terminating in a planar surface, engages the trunion. An acetabular cup member is provided for receiving the part-spherical head of a femoral implant, the cup member has a cavity having a part-spherical inner surface for receiving the modular head. The part-spherical inner surface of the cup defines a polar axis and an equator centered about a pole of the cavity. The cavity has a part-circular opening spaced from the pole a greater distance than the equator. Thus the inner part-spherical bearing surface extends beyond the 180° which the equator extends. The configuration of the part-spherical inner bearing surface causes a movement of translation of the head during rotation so that there is a crescent shaped retention area on each opposed side thereof. The opening has a non-circular or planar portion alignable with the planar head surface during insertion of the head in the cavity and a plane parallel to the non-circular portion through the center of the portion of the opening being offset from a parallel plane containing the polar axis of the cavity.

摘要： The socket (2) comprises a metallic outer shell (4), an intermediate shell (5) of plastics and a metallic inner shell (6), which may be inserted into the latter using a connection by shape. The outer shell (4) is divided into segments (4a, 4b, 4c, 4d, 4e) by recesses (9) open towards its equatorial marginal region. The outer shell (4) and the inner shell (6) are rigidly supported against each other in the direction of a common main axis (A) by a contact portion (8), and are non-rotatably connected by an attachment element (15) eccentrically offset with respect to the main axis (A). The intermediate shell (5) has an aperture (20), which receives the contact portion (8), and an outer surface (21), which has a supporting portion (21a) for bearing onto a portion of the inner surface (18) of the outer shell (4), and outside this supporting portion (21a) delimits with the remaining portion of the inner surface (18) a spacing (S), which allows corresponding relative movement of the intermediate shell (5), which contains the inner shell (6), and at least one of the segments (4a, 4b, 4c, 4d, 4e) of the outer shell (4) transversely to the main axis (A). The implanted outer shell (4) may, under load, elastically deform with the part of the bone by which it is surrounded, while the spherical shape of the inner shell (6) remains undisturbed.

摘要： A multi-component hip joint prosthesis is provided comprising an acetabular cup and a plastic bearing liner, each of which defines a segmented open shell with an inferior segment thereof removed to provide enhanced flexibility. The enhanced flexibility substantially facilitates the assembly and disassembly of the components. The liner and the cup are retained in their assembled condition by interengagement between a plurality of ridges and at least one groove on the respective components. The plurality of independent ridges enhances the flexibility of the ridges, thereby further minimizing the assembly forces required. Interengageable keys and keyways on the respective components may be provided to prevent relative rotation therebetween. The cup may comprise a removable tab to facilitate the insertion of a tool between the cup and the liner for prying the liner from the cup if necessary.
