    Abstract: The invention relates to an augment device, in particular a tibial augment for a knee joint endoprosthesis, comprising a hollow sleeve (10) surrounding a channel (11) extending through the hollow sleeve (10) from a top (12) to a bottom (14) of the hollow sleeve (10), the hollow sleeve (10) comprising a wall (17) having an inner face (14) and an outer face (15). According to the invention the hollow sleeve (10) comprises at least one bending joint (3´), the bending joint (3, 3´) being configured for compressing the channel (10). Thereby the hollow sleeve (10) may be compressed under an external force, leading to a decreased circumference and width of the hollow sleeve (10). This leads to a gap between the perimeter of the augment device (1) and surrounding bone material, breaking any connections. By virtue of this, a much facilitated removal of the augment device (1) can be achieved. Further, the invention provides an extraction tool (5) having grippers (6) for engaging and compressing the augment device (1), and further instruments, particularly a jig (8), for achieving an effective removal. The invention further relates to a corresponding method of handling the augment device (1).

    Abstract: Implantable drug-eluting device (1) comprising a microporous structure (2) having regularly arranged pores (4, 5) in at least two different uniform sizes, and manufacturing method. The pores are configured for receiving a drug (9) and are being connected by interconnections (6, 7). Interconnections (6) originating from pores (4) of a first size have a first elution area and interconnections (7) originating from pores (5) of a second size have a second elution area. The interconnections convey the drug (9) to a surface of the device for elution to surrounding tissue. The ratio between the first and the second elution areas is predefined and selectable. The differently sized elution areas provide for different outflow rates. This allows for simple but reliable dispensing of drugs at positively controlled and well determined rates. Particularly, this enables a single implantable device to dispense drugs over preselectable durations of time, like short-term or long-term.

    Abstract: The invention relates to an augment device for a joint endoprosthesis, in particular a tibial augment for a knee joint endoprosthesis, comprising a sleeve (10) surrounding a channel (11) extending through the sleeve (10). The sleeve (10) is formed of porous material (2) for ingrowth of bony material, the sleeve (10) comprising an inner face (14) and an outer face (15). The sleeve (10) further comprises a wall (3) surrounding the channel (11), the wall (3) being made of solid material and forming a sandwich structure with the porous material (2), wherein the wall (3) forms a bulkhead between the inner face (14) and the outer face (15). Thereby, the bulkhead wall (3) will stop inflow of any cement across the sleeve (10) from its inner (14) to its outer face (15). The porous material (3) on the outer face (15) 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.

    Abstract: A tibial component of a knee joint endoprosthesis comprises a laterally extending tibial plate (91), a distally projecting anchoring stem (8) with a shaft piece (82), and at least one laterally extending wing-like extension (83). In an implantation state, the tibial plate (91) and the anchoring stem (8) are connected to one another by means of detachable fastening elements. The tibial plate (91) is removable from the anchoring stem (8) for an explantation state. At least one spacer (7) that can be removed proximally is provided on the tibial plate (91), the end face (72) of which forms a stop for the extension (83) and is designed to form a stop between the extension (83) and the tibial plate (91) to create space (6) with a defined minimum width as a saw slot space.

    Abstract: 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.
