A screw suitable for use specifically in the field of oral dental surgery consists of a bioresorbable material and comprises a drive that can be broken off by means of a predetermined breaking point and/or has a thickened shaft below the contact surface of a cap of the head of the screw.

A femoral head arthroplasty system can comprise a femoral prosthesis comprising a mounting plate having a first side and an opposed second side. An adapter can extend from the second side of the mounting plate. An implant body can extend from the first side of the mounting plate. The implant body can extend from the mounting plate by a distance no greater than 90 mm. The femoral head arthroplasty system can further comprise a femoral head replacement having a generally spherical surface and comprising a recess that is shaped to complementarily receive the adapter of the femoral prosthesis.

The present invention relates to orthopaedic implants having a fenestrated hollow shell and a biologic core. These design features provide an improved interface between the implant and the surrounding tissue, aiding fixation, and provide a vehicle for applying new bone healing and enhancing modalities, such as gene therapy, tissue engineering, and growth factors.

Methods and apparatus for coating bone particles are provided. The methods and apparatus comprise providing a first mesh having a first set of openings to allow coating liquid and bone particles of a select size therethrough and bone particles larger than the select size to remain on the first mesh, the first mesh having a bottom portion; adding bone particles to the first mesh; and contacting the bone particles with coating liquid so as to allow bone particles larger than the first set of openings to remain on the first mesh so as to coat the bone particles.

A prosthesis for a synovial joint arthroplasty within a human body is provided. The prosthesis includes a first prosthetic component, the first prosthetic component including a first surface and the first prosthetic component being formed of a copolymer elastomer compound, the copolymer elastomer compound including a thermoplastic elastomer, a plurality of long glass fibers, the long glass fibers being randomly dispersed throughout the thermoplastic elastomer to improve surface fatigue life and inhibit surface crack propagation to the prosthesis and improve wear resistance of the prosthesis, a number of the plurality of long glass fibers protruding outward from the first surface of the first prosthetic component; a second prosthetic component, the second prosthetic component including a second surface, the second surface of the second prosthetic component positioned proximate the first surface of the first prosthetic component to engage the plurality of long glass fibers protruding from the first surface of the first prosthetic component allowing the second surface of the second prosthetic component to slide relative to the first surface of first prosthetic component while contacting the plurality of long glass fibers protruding outward from the first surface of the first prosthetic component, a gap, the gap created by the voids between the second surface of the second prosthetic component, the first surface of the first prosthetic component and the plurality of long glass fibers that protrude outward from the first surface of the first prosthetic component, the gap further disposed between the first surface of the first prosthetic component and the second surface of the second prosthetic component to allow the passage of fluid between the first surface of the first prosthetic component and the second surface of the second prosthetic component, a first trough, the first trough formed as the plurality of long glass fibers protruding outward from the first surface are forced into the thermoplastic elastomer as the prosthesis is loaded, the first trough positioned proximate each of the plurality of long glass fibers and encasing a perimeter of each of the plurality of long glass fibers.

The invention describes an implant for wear couples in endoprosthetics, the implant having an outer side, with an outer face, and an inner side, and a hemispherical wear region for accommodating a spherical wear partner being formed on the inner side. The aim of the invention is to reduce the height of the implant as much as possible and to ensure that, e.g., the pelvic bone does not have to be milled down as much. According to the invention, the implant is therefore designed in the form of a ring or annular structure and the outer face permits direct implantation in the body. In order to reduce friction between the spherical wear partner and the implant to a minimum, the implant has a specially designed inner geometry.

A device adapted to be positioned between two bone regions, the device comprising a body having a stabilising arrangement configured such that bone growing from one bone region toward the other engages the stabilising arrangement of the device.

Devices, systems, and methods for applying a bioactive coating to an exterior surface of an implant are disclosed. In some embodiments, the bioactive coating may be applied to the surfaces of the implant within the operating room at the time of implantation. In one embodiment, the implant may be a temporary spacer used to temporary replace an implant in a patient suffering from an infection. The temporary spacer being, for example, an antibacterial material for fighting the infection. In some embodiments, the method includes providing a mold of the implant, and providing the bioactive coating within the mold. The method may further include inserting the implant into the mold so that the exterior surface of the implant contacts the bioactive coating, and then removing the implant from the mold.

Devices and methods for orthopedic support are disclosed. The device can have a first rigid section hingedly attached to a second rigid section. The device can be curved or rotated around obstructions along an access path to a target site. The device can be delivered to an intervertebral location in a patient.

A method of preparing an interpositional implant suitable for a knee. The method includes determining a three-dimensional shape of a tibial surface of the knee. An implant is produced having a superior surface and an inferior surface, with the superior surface adapted to be positioned against a femoral condyle of the knee, and the inferior surface adapted to be positioned upon the tibial surface of the knee. The inferior surface conforms to the three-dimensional shape of the tibial surface. The implant may be inserted into the knee without making surgical cuts on the tibial surface. The tibial surface may include cartilage, or cartilage and bone.
