摘要： Disk-shaped augmentation for filling bone defects, in particular at the end of long bones, such as the tibia, including a first side, a second side, an outer sheath on lateral sides and an inner wall for a through-opening, running from the first to the second side, for a anchoring keel of an endoprosthesis arranged on the second side. The augment is generally C-shaped with two legs flanking the through-opening. According to the invention, a connecting piece between the legs is designed in an articulated manner and cooperates resiliently with the legs such that a frame is formed, and an outwardly directed restoring force is generated when the legs are compressed.

摘要： Modular endoprosthesis for at least partial replacement of a tubular bone, comprising, as module components, a stem for insertion into a bone cavity of the tubular bone, and an end piece comprising a support body with a neck part arranged on the medial aspect thereof. Said module components being able to be coupled to each other and released from each other along a longitudinal axis of the shaft. The end piece has at least two different surface configurations on its support body, namely a closed surface (6′) on a medial aspect, and a porous configuration of the surface on the opposite, lateral aspect. The latter permits and positions the adhesion of muscle tissue, specifically without suturing. The muscle trauma caused by suturing, and the peak loads that occur at the respective suture points, can thus be avoided by virtue of the invention, by means of the location-specific direct adhesion of the muscle. It is thus possible to achieve quicker and reliable mobilization of the patient, and this with a reduced risk of complications.

摘要： The invention relates to a bone implant, comprising a main body, which has, in its outer region, an open-cell porous lattice structure, which is formed from a plurality of regularly arranged elementary cells, the elementary cells being in the form of an assembled structure and each being composed of an interior and of a plurality of interconnected bars surrounding the interior. The porous lattice structure is provided with a bone-growth-promoting coating comprising calcium phosphate, the calcium phosphate coating having a hydroxylapatite proportion forming a pore inner coating extending into the depth of the porous lattice structure.

摘要： An augment device includes a hollow sleeve surrounding a channel extending through the hollow sleeve from a top to a bottom of the hollow sleeve, the hollow sleeve comprising a wall having an inner face and an outer face. The hollow sleeve includes at least one bending joint, the bending joint being configured for compressing the channel. Thereby the hollow sleeve may be compressed under an external force, leading to a decreased circumference and width of the hollow sleeve. This leads to a gap between the perimeter of the augment device and surrounding bone material, breaking any connections. By virtue of this, a much facilitated removal of the augment device can be achieved. Further, an extraction tool includes grippers for engaging and compressing the augment device, and further instruments, particularly a jig, for achieving an effective removal.

摘要： A prosthesis or implant device for use in joint or bone repair, or restoration of function. The prosthesis or implant device comprises a stem, in which a portion of the stem comprises non-overlapping lamellas around part or all of the circumference of the stem. Each lamella is connected to the external surface of the stem via a bending joint, which permits the space between the rest of the inner surface of the lamella and the external surface of the stem to decrease upon application of a force to the outer surface of the lamella. In addition, methods of treating a subject in need of joint replacement or bone repair using the prosthesis or implant device.

摘要： An augment device for a joint endoprosthesis, the device including a sleeve surrounding a channel extending through the sleeve. The sleeve is formed of porous material for ingrowth of bony material, the sleeve comprising an inner face and an outer face. The sleeve further comprises a wall surrounding the channel, the wall being made of solid material and forming a sandwich structure with the porous material, wherein the wall forms a bulkhead between the inner face and the outer face. Thereby, the bulkhead wall will stop inflow of any cement across the sleeve from its inner to its outer face. The porous material on the outer face will be kept free from cement and its capability to promote bone ingrowth is reliably preserved. The augment devices are preferably provided as a set having different sizes and straight or stepped bottoms for improved versatility and maximum preservation of natural bone matter.
