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.

A novel implant for replacing a portion of an articulation surface of a joint is disclosed. The implant includes a bone-engaging surface, a hydrogel portion forming an articulation surface opposite from the first bone-engaging surface, and a bone plate portion configured for securing the implant to a bone that forms the joint.

The application discloses an artificial acetabular cup and a manufacturing method thereof. The artificial acetabular cup has an annular base and a dome extending from the annular base. At least a part of the inner layer of the dome is a solid layer, at least a part of the outer layer of the dome is a porous structure layer, and the thickness of the inner layer is less than that of the porous structure layer. The artificial acetabular cup of the present application has lower production cost and better performance.

Various embodiments disclosed herein relate to stemmed and stemless humeral anchors for use in shoulder arthroplasty procedures. For example, the humeral anchor can include a first end, a second end, and an interior surface extending between the first end and the second end. The interior surface can be disposed about a recess disposed between the first end and the second end. The recess can be configured to secure a coupling of a shoulder articular body directly to the interior surface.

Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment.

Intersomatic cage for vertebral stabilization, including a generally prismatic body having an outer rigid framework in the form of a truss within which at least one insert incorporating slow prolonged release substances selected from the classes of anti-inflammatory, anti-infection and bone regrowth promoter drugs is housed.

A humeral implant is provided. The implant includes a humeral stem including a plurality of fins. At least one fin comprises a serrated bottom edge. A radial distance between an inner bottom edge of the at least one fin and a centerline of the humeral implant increases along a distal length of extension of the at least one fin. At least the serrated bottom edge of the at least one fin is configured to cut into and compact bone of the metaphysis of a humerus toward relatively denser cancellous bone of a peripheral portion of the humerus when press-fit therein, thereby providing sufficient press-fitting for cementless fixation of the humeral stem into the humerus. Related kits and methods are also provided.

An implant includes a component for fixed attachment to a bone. An underpass layer of a porous material is disposed on a first side of the component for fixed attachment. At least one strut is provided on the underpass layer. The at least one strut has a first surface contacting the underpass layer and a second surface opposite the first surface. The at least one strut comprises a non-porous material. An additional layer of the porous material fills a respective volume adjacent the at least one strut. The additional layer extends from a first side of the underpass layer to a predetermined height at or above the second surface of the at least one strut.

A tibial baseplate for tibial component of a knee prosthesis including: a bulk solid portion including a proximally facing surface adapted to accommodate a bearing element for the articulation of a femoral component of the knee prosthesis; a plurality of porous portions integral with the bulk solid portion having a porous portion contacting surface opposite to the proximally facing surface adapted to contact a proximal tibia. Advantageously, the plurality of porous portions are seamlessly incorporated and embedded in the bulk solid portion.

An motion preserving intervertebral disc replacement/fusion prosthesis, including an inferior component, including a first top surface, a first bottom surface, a chamber arranged between the first top surface and the first bottom surface, and a plurality of apertures extending from the first bottom surface to the chamber, a superior component, including a second top surface, and a second bottom surface, and a spacing element arranged between the first top surface and the second bottom surface. The prosthesis is arranged to allow a fusion or similar stable union between the prosthetic surfaces and adjacent vertebra elements, while allowing for normal motion between adjacent vertebrae once stable union between the prosthesis and the juxtaposed vertebral endplate and the prosthesis occurs, such union being facilitated by bio absorbable struts that prevent motion until device/endplate union is solid, but permitting fully normal range of motion of the device once strut dissolution has occurred.
