A flexible bone implant includes a proximal stem having a proximal end, a distal end, and a proximal conduit extending from the proximal end to the distal end of the proximal stem, whereby the proximal conduit is open at both the proximal and distal ends of the proximal stem. The implant includes a distal stem having a proximal end, a distal end, and a distal conduit extending from the proximal end to the distal end of the distal stem, whereby the distal conduit is open at both the proximal and distal ends of the distal stem. The implant includes a flexible hinge interconnecting the distal end of the proximal stem with the proximal end of the distal stem for allowing the proximal and distal stems to flex relative to one another. A proximal stem protective tube is disposed within the proximal conduit of the proximal stem and has a length that matches the length of the proximal conduit, and a distal stem protective tube is disposed within the distal conduit of the distal stem and has a length that matches the length of the distal conduit. The proximal stem, the distal stem and the flexible hinge comprise a unitary structure made of a polymer material.

An arthrodesis implant (1) for promoting the osseous fusion of a first bone (2) with a second bone (3), the implant (1) comprising a primary component (4) including a primary anchoring body (5) and a male connector (6), and a secondary component (7) including a secondary anchoring body (8) and a female connector (9), the female connector (9) comprising: a main body (10) which extends longitudinally between a rear end (11) linked to the secondary anchoring body (8) and an opposite front face (12), and which has a lateral wall (14) linking the rear end (11) to the front face (12), a housing (15) formed within the main body (10) and configured to receive the male connector (6) in order to link together the primary (4) and secondary (7) components, the female connector (9) further comprising an opening (18) which is formed in the main body (10), in communication with the housing (15), and which extends continuously on both the front face (12) and the lateral wall (14), and which is sized and configured to enable a lateral introduction of the male connector (6) into the housing (15) via the opening (18), each of the primary (4) and secondary (6) components forming an integral part made in one piece, and the primary (5) and secondary (8) anchoring bodies being respectively designed to ensure the insertion and anchoring of the primary component (4) into the first bone (2), and of the secondary component (7) into the second bone (3), by impaction or by forced wedging.

An arthrodesis implant (1) allowing promoting the bone fusion of two bones is provided, the implant (1) comprising: a rigid and non-deformable anchoring body (4), designed to ensure the anchoring of the implant (1) in a first bone (2), and a deformable portion (5) designed to ensure the anchoring of the implant (1) in a second bone. The deformable portion (5) comprises at least two anchoring arms (9, 10) which protrude beyond the anchoring body (4) from the base end (7) of the anchoring body (4), the anchoring arms (9, 10) being separated from each other by a free space (E) so as to be able to be brought closer to each other by deformation of the anchoring arms under the action of the second bone. At least one of the anchoring arms (9, 10) is provided with a longitudinal reinforcing fin protruding beyond the anchoring arm (9, 10) from a lateral side (20) of the anchoring arm (9, 10).

The present invention involves orthopedic implants of small joints in human, in particular a truly patient-specific bone implanting system comprising the implant and surgical tools fabricated by additive manufacturing techniques based on the inputs conforming to each patient's anatomy and obtainable from a wide range of existing 3-dimensional imaging and image processing technologies, which offers a substantial progress in logistics, efficiency of surgical operation, and functionality of treated bones.

Medical implants, specifically small to large orthopedic implant joint replacements. Systems and methods for manufacturing orthopedic implant joint replacements and their instrumentation.

The invention relates to an arthrodesis plate for the stiffening of joints, in particular finger joints, comprising a proximal and distal anchoring region which are connected to one another in a mechanically rigid manner, characterised in that at least one outer contour of one of the two anchoring regions has a cross-section which is undulating, for example roof-shaped, or is provided with alternating crests and troughs by means of coating, and/or has a transversal-sagittal cross-section.

A medical grade thermoplastic or polymer implant with an osteoconductive coating is provided, specifically for corrections of the distal and proximal interphalangeal toe joints of the foot. The implant can be either straight or angled, and can be either solid or cannulated for insertion. The implant is sized and shaped depending on the specific anatomy and desired correction. End portions of the implant may be coated with an osteoconductive coating that promotes bone growth, but may reduce radiolucency. Thus, a central portion of the implant may remain uncoated to increase radiolucency of the implant at the region where two bones come together.

In one embodiment, the present invention is a method of arthrodesis or osteosyntheses of a first bone part and a second bone part, including the steps of positioning a first fixation zone of an implant in the first bone part and a second fixation zone of the implant in the second bone part, both the first and second zones made of shape-memory material and, prior to positioning the bone parts, are in an inner position; and while the first fixation zone is within the first bone part and the second fixation zone is within the second bone part, fixating the respective first and second fixation zones within the respective bone parts through shape-memory action at body temperature.

An orthopaedic implant can replace a joint in a patient. The orthopaedic implant includes a first component having a first component surface and a second component having a second component surface. The first component surface and the second component surface mate at an interface. The first component surface includes a metal substrate, a nanotextured surface, a ceramic coating, and a transition zone. The nanotextured surface is disposed directly upon the metal substrate and has surface features in a size of 10.sup.9 meters. The ceramic coating conforms to the nanotextured surface and includes a plurality of bio-active sites configured to attract and retain calcium and phosphorous cations. The transition zone is disposed between the metal substrate and the ceramic coating. The transition zone includes a concentration gradient transitioning from the metal substrate to the ceramic coating and there is no distinct interface between the metal substrate and the ceramic coating.
