An orthopaedic hip prosthesis system is disclosed. The orthopaedic hip prosthesis system comprises a femoral head component configured to articulate with a natural or prosthetic acetabulum of a patient, the femoral head component having a tapered bore formed therein, a femoral stem component having a tapered trunnion configured to be received in the tapered bore of the femoral head component, and a shell positioned over the tapered trunnion of the femoral stem component. The shell includes a frame extending over the tapered trunnion, and a protective coating applied to the frame and the tapered trunnion. A method of performing an orthopaedic surgery is also disclosed.

The invention primarily relates to fastening and stabilizing tissues, implants, and/or bondable materials, such as the fastening of a tissue and/or implant to a bondable material, the fastening of an implant to tissue, and/or the fastening of an implant to another implant. This may involve using an energy source to bond and/or mechanically to stabilize a tissue, an implant, a bondable material, and/or other biocompatible material. The invention may also relate to the use of an energy source to remove and/or install an implant and/or bondable material or to facilitate solidification and/or polymerization of bondable material.

A human or animal joint is treated by introduction of a device between the suitably prepared articulating surfaces of the joint, and the device is anchored in both these articular surfaces with a material having thermoplastic properties. For allowing at least limited articulation of the joint after implantation, the device includes two articulating portions, wherein one of the articulating portions is anchored in each articulating surfaces of the joint. On implantation a proximal face of the device is contacted with a vibrating tool and the vibration is transmitted through parts of the device to locations in which the material having thermoplastic properties is near the bone tissue of the articulating surfaces of the joint and in which liquefaction is desired. The liquefied material penetrates the bone tissue and, on re-solidification forms a positive fit connection between the device and the bone tissue

A method for locating a material having thermoplastic properties in pores of bone tissue includes providing a pin having the material having thermoplastic properties and a core, wherein the material having thermoplastic properties is arranged on the circumferential surface of the core constituting an outer region of the pin. An opening is provided in the bone tissue, and the pin is positioned at least partly in the opening. The outer region of the pin is then impinged with mechanical vibration energy for a time sufficient for liquefying at least part of the material having thermoplastic properties, and, in a liquefied state, pressing it into the pores of the bone tissue surrounding the opening. The vibration energy is stopped for a time sufficient for re-solidification of the liquefied material, and then the core is removed.

The invention discloses a glenoid prosthesis baseplate, having a surface (1) for an artificial socket insert, an opposite fitting surface (2), and holes (2f) passing through the surfaces (1, 2), and feet (3) on the surface (1) for the artificial socket insert for fixing the artificial socket insert. The baseplate has at least two mounting tabs (4) connected to the edge (P) of the baseplate, and holes (4a) passing through each mounting tab (4), and the prosthesis baseplate is provided with at least two through holes (2f) passing through both the surface (1) for the artificial socket insert and the fitting surface (2), and each hole (2f) being in alignment with the axis of a through hole (4a) of the mounting tab (4).

The invention is directed to a meniscus prosthesis comprising an arc-shaped meniscus prosthesis body having a main portion (1) comprising a reinforcing part (2) and two end portions (1A, 1B) comprising fixation parts (2A, 2B), wherein the main portion (1) comprises a part made of a first biocompatible, non-resorbable material extending between the two end portions (1A, 1B), wherein the reinforcing part (2) and the fixation parts (2A, 2B) are made of a second biocompatible, non-resorbable material and wherein the reinforcing part (2) extends between the fixation parts (2A, 2B) and wherein the fixation parts (2A, 2B) have a through hole (3A, 3B), the first biocompatible, non-resorbable material has a tensile modulus of at most 100 MPa as determined by ISO 527-1 and the second biocompatible, non-resorbable material has a tensile modulus of at least 101 MPa as determined by ISO 527-1.

A hemi-prosthesis implant comprises a replacement-joint part with an articulation surface for tribological pairing with a joint surface of a natural joint counterpart. The articulation surface is embodied with a coating applied on a substrate. The substrate provides a relief for the adhesion of the coating. The relief may comprise one or more of a plurality of grooves, a plurality of teeth, a ribbing, and a roughened surface. The relief may be embodied entirely or partially outside the articulation surface. The replacement joint part may optionally comprise a ventilation feature, and the articulation surface may be formed by injection molding on the substrate. The hemi-prosthesis implant may be part of an implant set that includes both a hemi-prosthesis implant and a total prosthesis implant, either of which can be chosen intraoperatively.
