A composite threaded interbody device includes (a) an outer surface that is cylindrical or conical, (b) a plastic core having two outer sections, each of the outer sections forming a respective portion of the outer surface and spanning a respective azimuthal range in an azimuthal dimension relative to a longitudinal axis of the outer surface, the outer sections being separated from each other in the azimuthal dimension by two recessed sections that are recessed from the outer surface, and (c) two threaded endplates coupled to the two recessed sections and spanning gaps between the outer sections, to complete the outer surface.

The three-dimensional lattice structures disclosed herein have applications including use in medical implants. Some examples of the lattice structure are structural in that they can be used to provide structural support or mechanical spacing. In some examples, the lattice can be configured as a scaffold to support bone or tissue growth. Some examples can use a repeating modified rhombic dodecahedron or radial dodeca-rhombus unit cell. The lattice structures are also capable of providing a lattice structure with anisotropic properties to better suit the lattice for its intended purpose.

A bone graft containment device includes a body extending longitudinally from a first end to a second end. The body includes a channel extending longitudinally therethrough. The device also includes a fluid delivery structure received within the channel. The fluid delivery structure includes a central tubular member extending along a length of the channel and a laterally extending tubular member extending laterally from the central tubular member to a fluid receiving opening. The central tubular member includes a plurality of openings extending laterally through a wall thereof, so that, when the fluid receiving opening is connected to an external fluid source, fluid is passed through the laterally extending tubular member and the central tubular member to be dispersed to a graft material packed within the channel via the plurality of openings.

Various embodiments of implant systems and related apparatus, and methods of operating the same are described herein. In various embodiments, an implant for interfacing with a bone structure includes a web structure, including a space truss, configured to interface with human bone tissue. The space truss includes two or more planar truss units having a plurality of struts joined at nodes. Implants are optimized for the expected stress applied at the bone structure site.

To provide a porous plate for medical use which can suppress bending along a row direction and, even if a local crack occurs, can inhibit the crack from growing and leading to a fracture. One aspect of the present invention is a porous plate for medical use which is a thin-plate substrate provided with a pore perforation section having a plurality of pores perforated therein and a frame section surrounding the pore perforation section. In this porous plate, the pore perforation section has crosspieces which extend lengthwise and crosswise in continuity with the frame section and partition the pore perforation section into a plurality of parts, and a plurality of pore perforation cells each surrounded by the crosspieces. The pores perforated in the pore perforation cells have a pore diameter calculated as an equivalent circular pore diameter of 1 to 50 m, and the center-to-center distance between the adjacent pores is 2 to 200 m.

A bone implant for enclosing bone material is provided. The bone implant comprises a mesh having an inner surface and an outer surface opposing the inner surface. The inner surface is configured to receive a bone material when the inner surface of the mesh is in an open configuration. A plurality of projections are disposed on or in at least a portion of the inner surface of the mesh. The plurality of projections extend from at least the portion of the inner surface of the mesh and are configured to engage a section of the inner surface of the mesh or a section of the outer surface of the mesh or both sections of the inner and outer surfaces of the mesh in a closed configuration so as to enclose the bone material. A tray, a kit and a method of making the bone implant are also provided.

A bone-repair composite includes a core and a sheath. The core is a first primary unit including a combination of a first set of yarns coated with a calcium phosphate mineral layer. The first set of yarns being made from a first group of one or more polymers. The sheath is a second primary unit a combination of a second set of yarns or one or more polymer coatings. The second set of yarns being made from a second group of one or more polymers, wherein the composite is made by covering the core with the sheath, and the composite is compression molded to allow the sheath to bond to the core. The bone-repair composite has a bending modulus comparable to that of a mammalian bone, such that the ratio of the core to the sheath is provided to maximize the mechanical strength of the bone-repair composite to mimic the mammalian bone.

Devices and methods for orthopedic support are disclosed. The device can have a first rigid section hingedly attached to a second rigid section. The device can be curved or rotated around obstructions along an access path to a target site. The device can be delivered to an intervertebral location in a patient.

An implantable prosthetic device for the repair of damaged cartilage including methods of implantation and repair. The prosthetic device is formed from a biocompatible pad having an open structure connected to a textile or non-woven sheet-like anchor. In one embodiment the anchor comprises legs that extend away from a perimeter region of the pad and spaced apart along their respective lengths such that an in unfolded orientation, the longitudinal edges of neighbouring legs are not in contact with one another and a spatial gap is provided between the anchoring legs. The anchor may also be provided in the form of strips to which anchorage sutures or other medical cords may be attached to fixate the device between connective tissue.

A bone implant including a wire mesh support frame (120A) having a plurality of interconnected wire members and at least two fastening points in the form of retention eyelets (140A) connected to the support frame by deformable retention arms (138A), and a biocompatible plate (112) formed about the support frame, the plate having at least two open cavities (116) therein, wherein each of the retention arms extends out of the plate from or into one of the open cavities. A method for correcting a bone defect in a patient, a mesh support frame for use in a bone implant, and a method of fabricating a bone implant are also provided.
