Abstract: An anchoring unit is configured for anchoring a knee prosthesis component to a leg bone. The anchoring unit includes an anchoring sleeve having a sleeve wall. The sleeve wall defines a through-opening designed to receive a prosthesis stem. The sleeve wall has at least two wall sections that are formed separately from one another and made of a non-physiologically degradable material. The wall sections are connected to one another by at least one connecting section made of a physiologically degradable material. The anchoring unit can be part of a prosthesis kit.

Abstract: A method for producing a medical product includes the step of forming at least one functional element on a surface of a base body by additive construction or manufacture, followed by the step of connecting the at least one functional element to the base body.

Abstract: A medical system and method can be used to determine a treatment suggestion when treating a bone with an implant. In a memory device there are stored treatment data records for previous treatment interventions, containing parameter information, treatment information and success information. A data processing device determines, for an upcoming treatment intervention, at least one selected treatment kind with respect to a successful treatment intervention based on parameter information and depending on the linking of the success information with the parameter information of previous treatment interventions. A treatment proposal regarding the at least one selected treatment kind is output to the user.

Abstract: A tibial trial implant for use in a knee joint replacement operation includes an articulation component with an articulation surface for articulation with a femoral component, at least one support component having a bearing surface configured for bearing on a tibial plateau, a top side forming a ramp inclined relative to the bearing surface, and a guide device having a guide track parallel to the ramp. A bottom side of the articulation component has a support surface inclined parallel to the ramp. The articulation component is held on the guide device and supported with its support surface on the ramp in a manner linearly movable along the guide track relative to the support component. Relative movement between the articulation component and support component changes a proximodistal distance between the articulation surface of the articulation component and bearing surface of the support component.

Abstract: A bone implant system, a bone implant produced using such a bone implant system, and a method for producing such an implant. The bone implant system includes a plurality of different disc elements having different external diameters. The disc elements can be stacked axially above one another in different combinations to form different stack arrangements owing to the different external diameters of the disc elements. The different stack arrangements have different outer contours. The disc elements each have an interlocking portion situated on an upper face and a complementary interlocking portion situated on an axially opposite lower face, by which interlocking portions the disc elements can be interlockingly fixed to one another in the different stack arrangements in the radial direction and/or the circumferential direction.

Abstract: A medical product for use during the treatment of a bone defect, having a plurality of individual elements that are connected to one another such that individual elements adjacent to one another engage in one another/are chained to one another. The individual elements of the chain net are subdivided into main elements and connection elements that are designed differently from the main elements. The main elements and the connection elements form, when chained to one another, a grid structure that is flat in the x-y plane.

Abstract: A bone implant includes a main body in the form of a hollow body open on both sides in the axial direction. The main body includes a load-bearing material. An encasing body at least partially encases the main body on the outside and includes an in vivo degradable/in vivo resorbable material. Alternatively, the encasing body includes a multiplicity of shaped bodies protruding from the main body in the radial direction that include an in vivo degradable/in vivo resorbable material. A method for producing the bone implant includes an additive manufacturing process. The main body can be at least partially encased by the encasing body in the additive manufacturing process.

Abstract: A medical apparatus, medical method, data processing program and program storage medium. A piece of reference position information of a reference element arranged on a bone is checked for agreement with a position of the reference element in a reference coordinate system, which is defined by a marking device and can be monitored by a navigation device. The model data set can be registered in the reference coordinate system.

Abstract: An implant for treating a bone defect wherein the implant comprises osteoconductive supporting bodies and an insertion aid. The insertion aid is designed for insertion of the osteoconductive supporting bodies into a bone defect and for holding together the osteoconductive supporting bodies. Also disclosed is a kit comprised of an implant for treating a bone defect.

Abstract: An implant, in particular for the treatment and/or biological reconstruction of a bone defect, includes osteoconductive supporting bodies and a supporting sheath at least partially surrounding the osteoconductive supporting bodies. The sheath can be formed of a sheath material or can consist of a sheath material that is soluble in water or in water-containing liquids. A kit and method for the treatment and/or biological reconstruction of a bone defect can utilize a sheath for osteoconductive supporting bodies and a material for sheathing the osteoconductive supporting bodies.

Abstract: Medical-technical instrumentation and a medical-technical method that utilize a planning data set created for a surgeon on the basis of an actual state data set of a bone that is considered to be defective. The planning data set can be used intraoperatively for improving the surgery outcome.
