The plate member bisects the porous scaffolding. The plate member and the spaced support members define a unitary titanium body.

An intervertebral implant for being implanted between adjacent vertebrae is provided. The implant includes a generally elongate implant body having a length extending between opposite longitudinal ends thereof, a superior face and an inferior face. The superior face and inferior face include cortical teeth adjacent to the implant body longitudinal ends. Additionally, the superior and inferior faces include longitudinally central teeth intermediate the cortical teeth and have bone engaging ends. The central teeth have a sharper configuration than that of the cortical teeth bone engaging ends for biting into the softer central bone material of the vertebrae. The cortical teeth are arranged in a first density per unit area and the central teeth are arranged in a second density per unit area that is less than the first density.

An orthopedic implant can comprise a structural body, a plug and a frangible connection. The structural body can comprise a first surface, a second surface opposing the first surface, and a through-bore extending from the first surface to the second surface. The through-bore can have a bore surface. The structural body can be formed of a porous material. The plug can be disposed in the through-bore. The frangible connection can link the bore surface and the plug. A method of manufacturing an orthopedic implant can comprise producing a porous structural body having a port, producing a plug for positioning in the port, and producing a plurality of frangible crosspieces within the port to connect the plug to the structural body.

Cellulose-reinforced hydrogels may include a cellulose nanofiber network and an interstitial hydrogel portion within interstitial regions of the cellulose nanofiber network, the interstitial hydrogel portion comprising polyvinyl alcohol (PVA), wherein the hydrogel component has a crystallinity of 20% or greater.

In some implementations, the interbody implant may include an anterior side, a posterior side, a cephalad side, a caudal side, a right side, and a left side. In addition, the interbody implant may include a proximal end and a distal end. The interbody implant may include a mesh having a first set of pores having a first diameter based on a first relationship to a first locus and a second set of pores having a second diameter based on a second relationship to the first locus. Moreover, the interbody implant may include where at least one of the anterior side, posterior side, left side, right side, cephalad side, and caudal side may include the mesh.

A build-plate with integrally-formed spinal implant constructs and a method used in forming spinal implant constructs on the build-plate and machining the spinal implant constructs formed on the build-plate to manufacture spinal implants is provided. The spinal implant constructs can be formed via additive manufacturing processes by adding material to an upper surface of the build-plate, and then the spinal implant constructs can be subjected to subtractive manufacturing processes to form the spinal implants.

A medical implant for cartilage and/or bone repair at an articulating surface of a joint is provided. The implant includes a contoured implant body and at least one extending post. The implant body has an articulating surface configured to face the articulating part of the joint and a bone contact surface configured to face the bone structure of a joint, where the articulating and bone contact surfaces face mutually opposite directions and the bone contact surface is provided with the extending post. A cartilage contact surface connects the articulating and the bone contact surfaces and is configured to contact the cartilage surrounding the implant body in a joint. The articulating surface has a layer that is formed of titanium nitride (TiN) as the wear-resistant material. The cartilage contact surface has a coating that is formed of a material having chondrointegration properties.

A system and method for improving upon an ability of a surgeon to repair traumatic bone injury using new materials, components, and structures. A structure may be used as an implant or a component of an external fixator for a fractured long bone with that structure having anisotropic and viscoelastic properties, such as through additive manufacturing techniques.

An orthopaedic prosthetic component is provided. The orthopaedic prosthetic component comprises a porous three-dimensional structure shaped to be implanted in a patient's body. The porous three-dimensional structure comprises a plurality of unit cells. At least one unit cell comprises a first geometric structure having a first geometry and comprising a plurality of first struts, and a second geometric structure having a second geometry and comprising a plurality of second struts connected to a number of the plurality of first struts to form the second geometric structure.

An implant system for treating fractures of a curved bone structure is proposed which comprises the following: an implant body which is provided to be arranged on the bone structure and to be in contact with the latter at least in some regions, wherein the implant body has a rod-like longitudinal extent, wherein the implant body has at least one middle piece which, at both ends, has at least one respective holding piece, wherein the holding pieces are each designed to be flexurally and/or torsionally resistant in such a way as to allow the respective holding piece to rest substantially flat along a particular region of the bone structure assigned to it, and wherein the at least one middle piece is designed to be elastic in such a way that the at least two holding pieces are bendable relative to each other about at least one flexion or torsion axis.
