Abstract: The invention relates to a disc-shaped augmentation for filling bone defects, in particular at the end of long bones, such as the tibia, comprising a proximal side (12), a distal side (II), an outer casing (15) on lateral sides and an inner wall for a through-opening (2), running from the proximal to the distal side, for a stabilising keel (8) of an endoprosthesis (9) arranged on the proximal side. The augmentation is generally C-shaped with two sections (31, 32) flanking the through-opening. According to the invention, a connection part (30) is formed in an articulated manner between the flanking sections (31, 32) and elastically cooperating with the flanking sections (31, 32).

Abstract: An augment device for a joint endoprosthesis, the device comprising: a sleeve having a top and a bottom, a distance between said top and said bottom defining an entire height of said sleeve, wherein the sleeve surrounds a channel extending through the sleeve from the top to the bottom of the sleeve wherein the channel is configured to receive a stem of the joint endoprosthesis; the sleeve comprising an inner face and an outer face, the inner face defining the channel, and a distance between the inner face and the outer face defining a thickness; the sleeve further comprising a porous material configured for ingrowth of bony material.

Abstract: The invention relates to an endoprosthesis shaft system for elongate bones, comprising an anchoring part and a shaft, which is formed from module elements that can be coupled by means of a plug-in connection, wherein a mutual rotation of the elements along the shaft is adjustable and is blocked by means of an anti-rotation mechanism. In order to adjust the rotation, a rotation piece is provided as a further module element, which has a self-contained rotation adjustment device and a clamping device as a mechanism for blocking the rotation. The rotation piece comprises two end faces for the plug-in connection and a sleeve. The invention provides, with the rotation piece, a particular module element for the shaft, which as a structural unit allows both an adjustment of the rotation and a blocking against undesired rotation in a self-contained unit.

Abstract: The disclosure provides a tool for implanting an interphalangeal implant, an implant retainer for an interphalangeal implant, and a method for preparing an implantation tool for an implantation of an interphalangeal implant. The tool for implanting an interphalangeal implant comprises a limb support for supporting a limb, a driving rod, wherein the driving rod is movable for moving an interphalangeal implant towards the limb support, and an actuation mechanism for actuating the implant driver.

Abstract: Implantable drug-eluting device comprising a microporous structure having regularly arranged pores in at least two different uniform sizes, and manufacturing method. The pores are configured for receiving a drug and are being connected by interconnections. Interconnections originating from pores of a first size have a first elution area and interconnections originating from pores of a second size have a second elution area. The interconnections convey the drug 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: 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.

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