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 method and apparatus for introducing a shank (5) of a prosthesis into a bone cavity is disclosed. A strap 1 having an loop portion 2 and an end portion 3 is wrapped around the shank. The end portion of the strap is then clamped by a clamping device 4 to secure the strap around the shank. The bone cavity is filled with bone cement and the lower end of the shank is introduced into the bone cavity thereby forming a gap between the shank and the outer wall of the bone cavity. A strap substantially seals this gap to minimize leakage of bone cement from the bone cavity. The clamping device 4 allows the end portion of the strap to slip relative to the clamping device when a threshold force is applied against the clamping device. In this manner, the strap will conform to the increasing cross-sectional area of the elongate body of the shank as the shank is introduced into the bone cavity.

摘要: A hipjoint socket has an outer cup and an inner cup disposed within and secured to the outer cup. The inner cup has a hemispherical bearing surface which is concentric with an axis and terminates at the end face, which is perpendicular to the axis. An open groove formed in the end face is concentric with the axis. A closed ring has axially relatively longer and shorter portions and a cylindrical guiding surface having a diameter about equal to a diameter of the hemispherical guiding surface. The ring includes tongues engaging the groove and thereby securing the ring to the inner cup when the ring abuts the end face. The tongues are able to slide along the groove and position the cylindrical guiding surface concentric with the axis and substantially contiguous with an end of the hemispherical bearing surface at the end face. The ring can be rotated relative to the inner cup upon the implantation of the socket to position the relatively longer ring portion on the socket where it prevents luxation of a femur head cooperating with the socket.

摘要: An artificial acetabulum is made with a metal inner shell, a thin outer shell which defines a cavity with the inner shell and an elastic force-transmitting member between the two shells to damp forces imposed on the shells. In addition, a metal gauze layer is disposed about the outer shell for the ingrowth of osseous tissue. The inner and outer shells are connected at the edges so as to impermeable to air so that no particles from the cavity between the shells can reach the surrounding environment. A beading is also provided on the outer shell and/or gauze so as to snap into an appropriate undercut in the osseous tissue during primary implantation.

摘要: With the invention blocking systems for the medullary canal (1) of a tubular bone (2) are shown which have a blocking element (5) in order to hold bone cement (3) back from cemented prosthesis shafts (4). Because a deformable plug (6) which can be decomposed in the body is placed on between the blocking element (15) and the shaft end (7), which prevents an advance of liquid bone cement (3) in the capacity of a fill-in and which permits a penetration of the end (7) of the prosthesis shaft (4), a cement socket without a base arises which permits settling movements of the shaft in the hardened bone cement.

摘要: The shank for a femur head prosthesis is provided with a cavity in the approximate region which is filled with a plastic or elastic filler. A covering is provided over the filler to avoid contact between the filler and the bone or the bone cement surrounding the shank. The covering reduces the area of contact between the bone the filler to a minimum and limits the "flow" of the filler under compressive loadings on the head of the prosthesis.

摘要: The external bowl of the hip joint endoprosthesis is provided with a plurality of circumferential rows of projections. In addition, each projection is provided with a flank in a plane perpendicular to the axis of symmetry of the bowl and a second flank which faces the equatorial plane of the bowl which defines an angle of from 15.degree. to 45.degree. with the other flank. Upon penetration into bone tissue, the flanks displace and condense the tissue to approximately the same extent so that the axial force components acting on the flanks are approximately equal. This reduces the tendency of the endoprosthesis to be expelled from the bone.

摘要: A bone rasp has an elongate body which tapers in the distal direction with first cutting ribs which extend transversely to the longitudinal axis of the body and are arranged in parallel graduations at a first spacing along the longitudinal axis and with second cutting ribs which are formed in parallel graduations at a second spacing at the body. The first and second cutting ribs have a different depth of cut in order to ablate different amounts.
