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.

A novel hydraulic implant delivery system for introducing a hydrogel implant into a cartilage repair site is disclosed.

The present invention relates to a device and system for surgical fixation of small bones, small bone fragments, and osteotomies and more particularly to compression screw having an elongated and spiked tapered threaded leading portion which is joined to a section that is free from threads and a threaded trailing portion and more sharply tapered head which has threads that continue from the threads of the leading portion.

The present invention discloses a bionic artificial interphalangeal joint. The bionic artificial interphalangeal joint includes three sets of proximal prostheses and distal prostheses matched with the proximal prostheses and respectively corresponding to the three joints from the metacarpal bone to the distal phalanx. According to the specific position of the joint to be replaced, the corresponding artificial interphalangeal joint can be selected for replacement. Among them, the bionic artificial interphalangeal joint that can be installed between the metacarpal bone and the proximal phalanx has multiple degrees of freedom, which allows the proximal phalanx to bent in any direction like a real finger, and the bending angle of the proximal phalanx can be up to about 90 degrees when the proximal phalanx is bent toward the inner side of the finger.

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.

The present invention relates to a device and system for surgical fixation of small bones, small bone fragments, and osteotomies and more particularly to compression screw having a threaded leading portion which is joined to a section that is free from threads, and which includes an angle or from 12° to 25° in a plane through the longitudinal axis of the screw and a portion which is joined to a head having a configuration that is intended to provide anti-rotational stability and compression through the device.

The present disclosure provides a joint implant for replacing a finger joint. The joint implant includes a first component, wherein the first component includes a first joint section and a first anchoring section, the first joint section including a concave joint surface about a first axis and the first anchoring section extending transverse to the first axis. The joint implant also includes a second component, wherein the second component includes a second joint section and a second anchoring section, the second joint section including a circumferential surface about a second axis and the second anchoring section extending transverse to the second axis, wherein the circumferential surface includes a convex joint surface that is configured to act as a hinge joint with the concave joint surface of the first joint section.

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.

The disclosure provides a tool for implanting an interphalangeal implant, an implant retainer for an interphalangeal implant, and a method for preparing an implantation tool for an implantation of an interphalangeal implant. The tool for implanting an interphalangeal implant comprises a limb support for supporting a limb, a driving rod, wherein the driving rod is movable for moving an interphalangeal implant towards the limb support, and an actuation mechanism for actuating the implant driver.

An orthopaedic prosthesis is disclosed. The orthopaedic prosthesis includes a frame including a plurality of beams defining an open-cell structure and a shell applied to the frame. The frame includes a proximal arm, a distal arm, and a central body connecting the proximal arm to the distal arm. The shell extends over the proximal arm, the distal arm, and the central body of the frame. A method of implanting an orthopaedic prosthesis is also disclosed.
