Systems, methods, and devices described herein relate an implant adapted to be placed in a bone in the metatarsophalangeal joint or a metacarpophalangeal joint. In some embodiments, the implant includes a head portion extending from a first surface to a second surface and having a plurality of layers located between the first surface and the second surface. In some embodiments, the first surface is lubricious. In some embodiments, the implant comprises a post portion extending from the second surface of the head portion to a bone facing surface.

Metatarsophalangeal joint implants and methods thereof

Provided herein are biomimetic osteochondral implants that are generally useful for the at least partial resurfacing of damaged cartilage within a joint. The implants are constructed to have a modular, layered structure in which the physical properties (e.g., stiffness and lubricity) or dimensions of each layer can be adjusted (e.g., by using the appropriate material and controlling the thickness thereof) based on the anatomy to be replaced. For example, the material and or thicknesses of the layers can be selected to approximate the physical properties and/or dimensions of cartilage (and, optionally, chondral and subchondral bone). Also provided herein are methods of treatment involving the use of said biomimetic osteochondral implants to repair an osteochondral defect in a joint.

Multi-layered biomimetic osteochondral implants and methods of using thereof

A method for attaching a porous metal layer to a dense metal substrate, wherein the method is particularly useful in forming orthopedic implants such as femoral knee components, femoral hip components, and/or acetabular cups. The method, in one embodiment thereof, comprises providing a solid metal substrate; providing a porous metal structure; contouring a surface of the porous metal structure; placing the porous structure against the substrate such that the contoured surface of the porous metal structure is disposed against the substrate, thereby forming an assembly; applying heat and pressure to the assembly in conjunction with thermal expansion of the substrate in order to metallurgically bond the porous structure and the substrate; and removing mass from the substrate after the porous structure is bonded to the substrate, thereby finish processing the assembly.

Method for attaching a porous metal layer to a metal substrate

A hip spacer mold forming a spacer with a spacer stem connected to a spacer head has a stem portion for forming a spacer stem. The hip spacer mold also has a plurality of interchangeable head modules configured for alternatively forming spacer heads of a plurality of different predetermined sizes. The head modules are configured to be disposed adjacent the stem portion.

Spacer mold and methods therefor

The present disclosure relates to an orthopedic implant that may be used to repair and/or replace focal defects in an individual's articular cartilage. In one exemplary embodiment, the present invention provides a unitary orthopedic implant that includes a bone contacting layer and an articulating layer. In exemplary embodiments, the bone contacting layer may have a thickness of between about 1 millimeter and 3 millimeters. In exemplary embodiments, the articulating layer may have a thickness of between about 1 millimeter and 2 millimeters. As a result, the orthopedic implant may have an overall thickness of between about 2 millimeters and about 5 millimeters.

Unitary orthopedic implant

The present invention relates to a spacer, such as a polymeric spacer, for use with an implant device, e.g., a bone plate, for splinting a fracture of a bone. The spacer includes a body defining a bone healing surface, wherein at least a portion of the bone healing surface has a coating which includes a therapeutic agent, a polymeric carrier, and a buffer medium to stimulate bone growth and/or promote fracture healing. A kit is also disclosed which includes one or more of the spacers, at least one bone plate, and optionally one or more bone screws for securing the bone plate to bone. A method for promoting fracture healing in bone is further disclosed which includes securely situating a coated portion of the spacer adjacent bone.

Method for attaching porous metal layer to a metal substrate

The present invention provides hydrogel coated, implantable medical devices and methods of coating hydrogels onto implantable medical devices. In one embodiment, a hydrogel coated medical device is formed by physically treating a surface of the medical device, chemically treating the surface, applying a hydrogel precursor and then crosslinking the hydrogel precursor to form a hydrogel coating on the surface of the medical device. The present invention may be particularly applicable for coating articulating surfaces on implantable medical devices such as artificial joints.

Methods of preparing hydrogel coatings

In one aspect of the invention, an implant includes first and second components to replace a portion of each of a pair of opposed articulating bone ends. The second component has means for low friction articulation with the first component and means for engaging the first component to constrain the motion between the components. The means for low friction articulation includes a first material exhibiting low wear and having a predetermined toughness value. The means for engaging includes a second material having a predetermined toughness value higher than the means for low friction articulation.

Multipart component for an orthopaedic implant

A method for producing a zirconia-layered orthopedic implant component includes depositing zirconium onto the orthopedic implant component, thereby forming a zirconium-layered component, and converting at least a portion of the zirconium into a substantially monoclinic zirconia surface layer unaccompanied by a substantial underlying &#x3b1;-phase. A method for producing a zirconia-layered orthopedic implant component includes depositing zirconium onto the orthopedic implant component by ion bombardment and deposition in a vacuum to form a zirconium-layered component including an intermix zone at least 1000 &#x212b; thick and a zirconium layer about 3-5 &#x3bc;m thick, and heat treating the zirconium-layered component at a temperature of about 500-600&#xb0; C. in an atmosphere containing oxygen.

Method for producing a zirconia-layered orthopedic implant component

A method is provided for annealing a polymer for an orthopaedic implant by immersing the polymer in a liquid bath.
