摘要: An intervertebral implant for positioning within an intervertebral space between adjacent first and second vertebral bodies. The intervertebral implant includes an implant body extending along a longitudinal axis of the intervertebral implant that is adapted to align with a vertical axis of the spine. The implant body includes a top plate and a bottom plate disposed longitudinally opposite and spaced apart from the top plate along the longitudinal axis. Further, the implant body includes at least one cross-arm obliquely extending between the top plate and the bottom plate. Furthermore, the implant body includes a lattice structure disposed at least between the at least one cross-arm and the top plate and between the at least one cross-arm and the bottom plate.

摘要: A laterally deflectable asymmetric implant for implanting into a body may comprise a deflectable piece having distal and proximal ends and assuming a straightened insertion state. The backbone may abut or interconnect with said deflectable piece at the distal end of the deflectable piece. In a fully deflected state the implant may define an asymmetric shape, e.g. a D-shaped loop, defining an at least partially enclosed volume. The deflectable piece may comprise a sequence of segments interconnected at effective hinges. Longitudinal pressure applied to the proximal end of the deflectable piece (or applied to the backbone in an opposite direction) may cause relative longitudinal movement between the backbone and the proximal end of the deflectable piece and may generate outward horizontal movement of the deflectable piece away from the backbone. In one embodiment, the implant is implanted using lateral access into an anterior zone of a vertebra and deployed posteriorly.

摘要: An intervertebral implant comprising a body formed as an open truss structure, the body having a generally annular shape with a superior surface, an inferior surface, and a perimeter surface extending around an outer periphery of the body. The body may have a central portion and a peripheral portion, the peripheral portion extending inward from the perimeter surface toward the central portion, the peripheral portion including a first set of trusses, and the central portion including a second set of trusses. The implant may further include a strut at least partially defining a boundary between the central portion and the peripheral portion, wherein the strut has an oblong cross-sectional shape oriented to facilitate flow of bone graft material in a substantially radial direction away from the central axis.

摘要: The present invention discloses a metal-ceramic composite joint prosthesis and applications and a manufacturing method thereof. The joint prosthesis comprises a metal body and a ceramic body, wherein the metal body is integrally formed and comprises a porous structure layer, a boundary layer and a root-like layer, the boundary layer is located between the porous structure layer and the root-like layer, the root-like layer comprises a plurality of root-like filament clusters connected to the boundary layer but not in contact with one another, each root-like filament cluster comprises a main root perpendicularly connected to the boundary layer and a plurality of fibrous roots connected to the lateral side of the main root, the fibrous roots extend obliquely towards the side away from the boundary layer, and the ceramic body covers the root-like filament clusters and is formed on the boundary layer. The joint prosthesis achieves the compositing of metal and ceramic, thereby achieving both a wear-resistant ceramic body required for a joint friction surface and a porous metal structure with a good bone ingrowth effect required for an osseointegration surface. The root-like filament clusters of the root-like layer are rooted in the ceramic body, to form a tight and stable connection between the ceramic body and the metal body, and the root-like clusters being not in contact with one another prevents the ceramic body from locally breaking or cracking.

摘要: The methods disclosed herein of generating three-dimensional lattice structures and reducing stress shielding have applications including use in medical implants. One method of generating a three-dimensional lattice structure can be used to generate a structure lattice and/or a lattice scaffold to support bone or tissue growth. One method of reducing stress shielding includes generating a structural lattice to provide sole mechanical spacing across an area for desired bone or tissue growth. Some examples can use a repeating modified rhombic dodecahedron or radial dodeca-rhombus unit cell. Some methods are also capable of providing a lattice structure with anisotropic properties to better suit the lattice for its intended purpose.

摘要: A medical implant for cartilage and/or bone repair at an articulating surface of a joint 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 a wear-resistant material. The cartilage contact surface has a coating that is a bioactive material.

摘要: Methods for altering the natural history of degenerative disc disease and osteoarthritis of the spine are proposed. The methods focus on the prevention, or delayed onset or progression of, subchondral defects such as bone marrow edema or bone marrow lesion, and subchondral treatment to prevent the progression of osteoarthritis or degenerative disc disease in the spine and thereby treat pain.

摘要: Low profile offset reamers include reamer heads with outer diameters that are substantially greater than the overall height of the working portion, which includes the reamer head, a reamer coupler, and a working tip that supports the reamer head and reamer coupler. The overall height is measured parallel to the rotational axis of the reamer head, and the outer diameter is measured perpendicular to the rotational axis.

摘要: At least one bone fixation device comprising a stem having a maximum outer diameter is inserted into the sacroiliac joint through a minimally invasive incision path sized approximately at or about the maximum outer diameter of the stem in soft tissue, into the iliac bone, across the sacroiliac joint and into the sacrum. The stem is inserted through the incision path to a position within the sacroiliac joint between the iliac bone and the sacrum, to fuse the sacroiliac joint, without invasive joint preparation, removal of cartilage, or scraping at or near the sacroiliac joint. Desirably, at least a portion of the stem includes a surface permitting bony in-growth.
