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.

The invention relates to an attachment member (2) and a connecting member (16) for a carpometacarpal thumb joint prosthesis (1) as well as to said thumb joint prosthesis. The attachment member (2) comprises a screw-like part (4) for attachment by screwing into the second metacarpal bone and a locking device (8) for locking the screw-like part to the connecting member (16). The connecting member comprises an elongated, arcuate element (16) which at one end portion (16a) thereof is configured with a hole (14) for connection to the attachment member (2) for the second metacarpal bone and which at the opposite end portion (16b) thereof is configured with a hole (15) for connection to an attachment member (3) for the first metacarpal bone. The joint prosthesis (1) comprises said attachment member (2) for the second metacarpal bone, an attachment member (3) with a screw-like part (5) for attachment by screwing into the first metacarpal bone and with an articulating ball element (6) as well as a corresponding articulating socket element (7), and said connecting member (16).

This invention includes malleable, biodegradable, fibrous compositions for application to a tissue site in order to promote or facilitate new tissue growth. One aspect of this invention is a fibrous component that provides unique mechanical and physical properties. The invention may be created by providing a vessel containing a slurry, said slurry comprising a plurality of natural or synthetic polymer fibers and at least one suspension fluid, wherein the polymer fibers are substantially evenly dispersed and randomly oriented throughout the volume of the suspension fluid; applying a force, e.g., centrifugal, to said vessel containing said slurry, whereupon said force serves to cause said polymer fibers to migrate through the suspension fluid and amass at a furthest extent of the vessel, forming a polymer material, with said polymer material comprising polymer fibers of sufficient length and sufficiently viscous, interlaced, or interlocked to retard dissociation of said polymer fibers.

An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

Provided herein are methods, constructs, and kits for positioning a first bone segment relative to a second bone segment within a subject's body, for example, in order to establish a reduced position of the first and second bone segments. The present disclosure provides, among other things, alternatives to traditional ligament reconstruction and tendon interposition (LRTI) and suture suspension arthroplasty procedures.

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.

An implant that facilitates the fusion of a first bone part with a second bone part includes an implant body that extends between the first bone part and the second bone part. The implant body includes a first portion that fits within a first receiving aperture in the first bone part, and the implant body includes a second portion that fits within a second receiving aperture in the second bone part. At least one of the first portion and the second portion can be made of bone. Additionally, at least the second portion is formed to have a non-circular cross-sectional shape to inhibit relative motion between the bone parts and the implant body.

Devices, systems, and methods for bone stabilization, especially ulna head stabilization. The stabilization system may include a bone plate having an elongated portion extending along a longitudinal axis between a proximal end and a distal end. The bone plate defines a plurality of through holes extending through the elongated portion. A plurality of fasteners are configured to extend through one or more of the plurality of through holes in the bone plate and configured to secure the bone plate to the bone. The proximal end of the elongate portion has an arcuate configuration.

The invention relates to a resorptive intramedullary implant between two bones or two bone fragments. The implant includes a single-piece body (1) having a generally elongate shape and having, at each end, areas for anchoring to the bone portions in question, characterized in that one of said areas (A1) has a cylindrical cross-section while the other area (A2) has a flat cross-section.

An implant including a first segment at a first end, a second segment at a second end, and an intermediate segment coupled to the first segment on a first end and coupled to the second segment on a second end. The first segment may include an insertion tip at the first end of the implant and a body portion adjacent to the insertion tip, the insertion tip extending out from the body portion. The second segment may include an end member at the second end of the implant and a body portion adjacent to the end member, the end member extending out from the body portion. The second segment may include a plurality of tip portions spaced about a longitudinal axis of the second segment, and the tip portions each including at least one barb formed by a taper portion and an engagement portion extending radially into the tip portion.
