The shim-type implant for distraction and fusion of cervical facet joints is provided. The implant has a generally box-like shape with a blunt leading edge that may be centered or offset to the inferior face. The implant may include a graft window for enhanced osseous through-growth after implantation. The implant is coated with hydroxyapatite (HA) and/or tri-calcium phosphate (TCP) to allow for osteo-conduction, is porous, and has a roughened surface with serrations on the superior and inferior faces. The implant may be fabricated from a titanium or tantalum alloy. In an embodiment, a set of tools is provided with a chisel and one or tongs and one or more decorticators for inserting the implant.

A femoral prosthesis system for an orthopaedic hip implant and method of use is disclosed. The prosthesis system includes a femoral stem component that includes a core body and a casing that encases the core body. The casing can be additively manufactured such that the core body defines a predetermined orientation in the core body among a plurality of permissible predetermined orientations. The femoral stem component can further include a neck and a trunnion that extends from the neck. The neck can extend out with respect to the core body at a predetermined angle within a range of permissible predetermined angles.

In one embodiment, the present disclosure relates to a broach for use in a mammalian femur. The broach includes a body with a proximal portion and a distal portion extending from the proximal portion. The proximal portion has a first surface with a plurality of first teeth and the distal portion has a second surface with a plurality of second teeth. Each of the second teeth is different from each of the first teeth. And, each of the plurality of second teeth include pointed protrusions extending outward from the second surface.

A tissue fixation implant that includes leading fixation and trailing fixation members, each fixation member having a proximal head and an elongate shank with a distal tip, and each fixation member adapted to at least partially contact the other fixation member at one or more points along their respective lengths. The tissue fixation implant includes a proximal inter-engagement feature for fixedly engaging each of the two fixation members relative to one another when engaged within tissue, including bone tissue, soft tissue, and combinations of these, and has an interior chamber suitable for receiving osteogenic material to enhance new bone growth and fusion of the fixation implant within bone.

Augment element for knee prosthesis, comprising a metal body of a substantially truncated conical shape configured to be inserted into a bone extremity and having an outer surface comprising a metal trabecular surface. The metal body being hollow with an axial through-cavity defining a plurality of substantially annular transversal sections. The metal body is inclined in a direction of inclination, so as to define at least one eccentricity between a first transversal section at a first end of the axial through-cavity and a second transversal section at a second end of the axial through-cavity. The augment element further comprises a plurality of through-slits in the metal body, open from the first end up to an intermediate portion on the metal body, wherein the plurality of through-slits is configured for a radial compression of the metal body, locally reducing a circumference of the substantially annular transversal sections during insertion of the augment element, and increasing a press-fit towards a bone portion.

A device adapted to be positioned between two bone regions, the device comprising at least one wall defining at least one interior cavity, and, a load arrangement extending from the wall and comprising at least one interacting feature configured to load material positioned within the cavity by interacting with either a second interacting feature or the wall.

Implants, devices, and methods for maintaining, correcting and/or fusing joint deformities are disclosed. The implant a first member, a second member, and an insert with a top surface and a bottom surface. The top surface couples to the first member and the bottom surface engages the second member. Kits and methods of using the implants for maintaining, correcting and/or fusing joint deformities are also disclosed.

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.

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.

Methods of forming topographical features on an article, for example on a medical devices that has a surface configured to promote the migration of cells onto the surface of the medical device. In particular, the resulting surface of the medical device has a noncontiguous pattern of topographical features formed therein or thereon.
