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.

A joint implant component () for administering a pharmaceutical product is disclosed, which comprises an implant shaft (), a joint section () arranged at the proximal end of the implant shaft, a flush supply opening () and a backflush opening (). At least one shaft flush channel () and one shaft backflush channel () extend along the implant shaft inside the implant shaft. The shaft flush channel is connected to the outside of the implant shaft via shaft flush holes () for discharging the pharmaceutical product, and the shaft backflush channel is connected to the outside of the implant shaft via at least one shaft backflush hole () for receiving the discharged pharmaceutical product. The flush supply opening is fluidically connected to the proximal end of the shaft flush channel and the backflush opening is fluidically connected to the proximal end of the shaft backflush channel. Also disclosed is a joint implant comprising two such joint implant components which are connected to one another by means of joint surface parts () and are pivotable relative to one another.

Hip joint implant for fastening to a pelvic bone (), with a support body which has a socket () and whose convex outer face is designed to bear on the pelvic bone () and which, on its concave inner face, has a receiving seat for a pelvis-side bearing that is designed to receive a joint head of a femoral component of a hip prosthesis, and with outwardly directed flat fastening brackets () which are arranged at the edge region of the socket () and are each provided with at least one receiving seat for a fastening means. The fastening brackets () are made of a reshapeable biocompatible material and are connected to the socket () via a non-releasable cohesive bond (), wherein the socket () is made of another, stiffer biocompatible material. A high degree of robustness of the socket () is thus combined with what is, by virtue of the reshapeability, an improved adaptation to the anatomical conditions of the respective pelvic bone. This improves reliability of fastening, stability and long-term behavior.

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.

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.

A coating for an implant component, in particular a component of a spinal implant, is provided. The coating is a ceramic titanium nitride coating comprising an at % content of 5 to 30 At % of Ag in addition to an at % content of Ti and an at % content of N.

Anti-microbial implant coating

The invention relates to a coating for an implant component, a method for producing an implant component having said coating, and a use of said coating on an implant component. The coating is intended for an implant component, in particular a spinal implant component, and is a TiNb coating which has, in addition to an atom % proportion of Ti and an atom % proportion of Nb, an atom % proportion of 5-30 atom % of Ag.

Ductile coating for an implant component

The present invention relates to an implant comprising an implant body having a first surface area configured for contact with soft connective tissue and a second surface area configured for contact with bone tissue, wherein the first surface area is covered with a coating comprising tantalum and the second surface area is formed by a material, which is different than the one forming the coating.

The present invention provides a method for treating a polymer workpiece for use in a joint implant. It comprises the steps of placing the polymer workpiece in an explosion chamber, introducing a combustible gas mixture into the explosion chamber and igniting the combustible gas mixture. Igniting the gas mixture in the explosion chamber produces a temperature that lies above the melting point of a polymer of the polymer workpiece.

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.
