Disclosed is a wrist prosthesis, and methods for implanting same, the prosthesis comprising an elongated radial component having two opposite sides, the first side comprising a stem and the second side comprising a concave dish; an elongated carpal component having two opposite sides, the first side comprising a stem, and the second side comprising a ball end; a lunate component having two opposite sides, the first side comprising a cavity adapted to receive said carpal component's ball end, and the second side comprising a convex surface adapted to engage said radial component's concave dish; wherein said lunate component freely rotates and swivels with respect to both of said carpal and radial components; wherein said stem of said carpal component is adapted for rigid engagement with one or more carpal and/or metatarsal bones; and wherein said stem of said radial component is adapted for rigid engagement with a radius bone.

A trapeziometacarpal joint implant includes a body defining a median plane, a metacarpal joint surface, and a trapezium joint surface. A first central region of the metacarpal joint surface is situated on an opposite side of the median plane from a second central region of the trapezium joint surface. The first and second central regions correspond to profiles of a first axial segment and a second axial segment, respectively. The first and second axial segments are one of a cylinder, a cone and a torus and are centered on a first axis and a second axis, respectively, where the first and second axes, as projected on the median plane, are substantially perpendicular to each other.

A device is provided including a distal nail portion and a proximal nail portion that can be connected to each other to attain a rigid configuration. The device is to be placed internally within the medullary cavities of bones. The device is placed intramedullarily in order to minimize incision size, excessive bone resection and post-operative tendon damage and tenderness. Additionally, one particular method for using the device is provided that includes placing and affixing the distal nail in bone, placing the proximal nail in bone, connecting the distal nail to the proximal nail, doing the desired geometrical adjustments, affixing the proximal nail to the distal nail by tightening the connection and affixing the proximal nail to attain a rigid configuration.

A bone joint repair and replacement assembly. A first portion comprising a bone plate is configured to attach to a distal or proximal end of a bone proximate the joint, generally coaxially with an axis defined by the bone. A second portion comprising an articular surface is configured to attach to the first portion, generally normal with respect to the axis, and inserted into the joint. Although versions of the assembly can be configured for use with several different pivotal joints, the invention is particularly suitable for full or partial replacement of an elbow, wherein the articular surface is pivotally attached to the first portion. Another embodiment of the invention is provided to repair a fractured bone head proximate the joint, and still another embodiment of the invention is provided to repair rotator cuff-related shoulder injuries.

A prosthesis for reconstruction of a distal radioulnar joint, after resection of a part of the ulna, includes a first prosthesis member, fixation members and a second prosthesis member. The first prosthesis member is configured for fixation to the distal end portion of the ulna. The fixation members are configured to extend into the radius via said distal end portion of the ulna for locking said distal end portion of the ulna to the radius. The second prosthesis member is configured for fixation to the ulna close to said distal end portion of the ulna. The second prosthesis member is also configured to extend into said space for being joined with the first prosthesis member in a manner which allows said first and second prosthesis members to at least pivot and rotate relative to each other.

An apparatus and method for the repair of disruptions between bones. The apparatus defines a combination of sleeves, strands and crimps are provided to secure the bones, using a dual sided drill guide to prepare the bones for installation of the apparatus, which is adjusted upon installation to suit the appropriate alignment and tension of the apparatus. The method includes the preparation of the bones, the installation of the apparatus and the adjustment of the apparatus to properly align and tension the apparatus for repair of the bone.

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 wrist endoprosthesis (2) for functional replacement of the human wrist, containing a radius component (4) that has a shaft (10) for anchoring in the radius, a head (12), and a first joint surface (16), which is implemented on a distal head face (14), and a carpal component (6) that has a proximal carpal face (22), a distal carpal face (20) and a second joint surface (24) which is formed on the proximal carpal face (22) and interacts with the first joint surface (169) of the radius component (4), characterized in that the carpal component (6) is substantially trough-shaped, in order to at least partially surround the carpal bones. Also, a wrist endoprosthesis (2) that has anti-luxation protection (8), a method for producing wrist endoprostheses (2) and a computer program product.
