The invention relates to an augmentation device comprising an annular cone surrounding a channel which extends axially along a longitudinal axis of the augmentation device from a proximal cone end to a distal cone end, wherein an outer diameter of the cone decreases from the proximal cone end in the direction of the distal cone end.

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.

An orthopaedic prosthesis includes a femoral component configured to be attached to a distal end of a patient's femur. A tibial tray is configured to be attached to a proximal end of a patient's tibia. A tibial insert is configured to rotate relative to the tibial tray. A modular insert is received in a cavity defined in the tibial insert. The femoral component is rotatably coupled to the body of the modular insert.

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.

A tibial augment for use with a knee joint prosthesis, composed of annular members of different stock sizes, each size being configured to fit within a cavity formed in a human tibia. The augment may include a stepped distal surface. A provisional (temporary) tibial augment used to ensure a proper fit for the permanent augment is also provided. The provisional may include grooves configured to cooperate with a set of ribs on a tong-like holder used for removing the provisional from the cavity. A pusher for use implanting the tibial augment is also provided. In addition, a system for creating a cavity in a human tibia is also described. The system preferably includes a guide with a slot therein and a set of osteotomes that are inserted to within different portions of the slot. Methods for using the tools and/or implanting the prosthetic devices discussed above are also described.
