An implant that couples a first bone and a second bone includes a body that defines a first joint surface, a second joint surface, and a median plane. The first joint surface includes a first central region that articulates with the first bone. The second joint surface includes a second central region that articulates with the second bone, and the second central region is disposed on an opposite side of the median plane of the body relative to the first central region. The first and second central regions correspond to profiles of first and second axial segments, respectively, the first and second axial segments are each one of a cylinder, a cone, and a torus and are centered on first and second axes, respectively, and the first and second axes, as projected on the median plane, are substantially perpendicular to each other. The first joint surface further defines a first peripheral region adjacent the first central region and the first axial segment has a first cross section that has a smaller curvature in the first central region of the first joint surface than in the first peripheral region of the first joint surface.

Interposition implants for the hand

Methods of implanting a prosthesis to repair a joint include exposing a first bone of the joint; resecting an end portion of the first bone to form a resected end defining a resection plane; forming a concavity in the resected end portion of the first bone using a shaping tool, the concavity extending at least through a full hemispherical arc; selecting a diameter of the prosthesis to be implanted; and implanting a prosthesis having the selected diameter in the concavity.

Intra-articular joint replacement and method

The present invention relates to an in vitro method for creating a viable connective tissue and/or osseous tissue obtained by tribological solicitations of a biological culture. It further relates to a viable connective tissue and/or osseous tissue susceptible to be obtained by said method as well as to the use of said method or viable connective tissue and/or osseous tissue to prepare a biological implant.

In vitro method for creating a viable connective tissue and/or osseous tissue

Methods of implanting a prosthesis to repair a joint include displacing a first bone from the joint formed by an intersection between the first bone and a second bone. An end portion of the first bone is resected to define a resected end. A concavity is formed into the resected end using a shaping tool. The bone is compacted to form a support layer lining the concavity. The prosthesis is implanted in the concavity against the support layer without attaching the prosthesis to the support layer. The joint is reformed with the prosthesis such that the prosthesis remains unattached to the support layer and the first and second bones articulate about the prosthesis.

An implant couples a first bone of a hand to a second bone of the hand. The implant includes a body that defines a median plane. The body also defines a first joint surface having a first central region that articulates with the first bone. The body further defines a second joint surface having a second central region that articulates with the second bone, and the second central region is disposed on an opposite side of the median plane of the body relative to the first central region. The first and second central regions correspond to profiles of first and second axial segments, respectively, the first and second axial segments are each one of a cylinder, a cone and a torus and are centered on first and second axes, respectively, and the first and second axes, as projected on the median plane, are substantially perpendicular to each other.

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.

Trapeziometacarpal joint implant and associated methods

A prosthetic assembly and a method of assembling same. The prosthetic assembly includes a base component with at least one engagement surface. A pyrolytic carbon component includes at least one engagement surface. The pyrolytic carbon component is elastically deformed to mechanically interlock with the engagement surface on the base component. The pyrolytic carbon component retains at least a portion of the deformation stress created during coupling with the base component.

Method and assembly of a pyrolytic carbon component attached to another component

A method and apparatus for replacing an articular surface of a bone. The implant includes at least one head with a bore and a lateral articular surface generally perpendicular to an axis of the bore. A holding element includes a stem at a proximal end adapted to attach to the bone. A member at a distal end of the holding device is adapted to engage with the bore in the head so that the lateral articular surface is positioned to engage transverse loads. The bore permits limited lateral translation of the head in at least one direction generally perpendicular to a longitudinal axis of the member.
