An orthopedic assembly includes a tibial prosthesis that includes a body that defines an anterior side and a posterior side. The body further includes a recess in the anterior side of the joint prosthesis and a plurality of openings that extend through the body from the anterior side to the posterior side thereof. At least a first and second opening of the openings are positioned at respective lateral and medial sides of a longitudinal axis of the tibial prosthesis. A modular insert is positioned within the recess of the body such that at least a portion of the modular insert is positioned between the openings of the body. The modular insert is formed separately from the tibial prosthesis and has a porous outer surface to promote tissue ingrowth.

A modular instrument system for use in a knee joint replacement operation includes a tibial component, a first femoral component, a second femoral component and at least one spacer element. The different components of the modular instrument system are releasably connectable to one another to form different instrument configurations.

A humeral head assembly is provided that includes an articular body and a coupler. The articular body includes a coupling portion disposed on a side of the articular body opposite an articular surface. The coupling portion includes a continuous zone of eccentricity adjustment. The coupler portion optionally includes one or more than one discrete position site. The coupler includes a first portion and a second portion opposite the first portion. The first portion is configured to mate with the coupling portion and the second portion is configured to mate with another member of a joint prosthesis. A coupling portion with the continuous range of eccentricity adjustment can be provided on a bone anchor and the eccentricity of another component can be selected by motion of a coupler, such as a tray for reverse humeral assemblies, along the coupling portion of the anchor.

An orthopedic assembly includes a tibial prosthesis that includes a body that defines an anterior side and a posterior side. The body further incudes a recess in the anterior side of the joint prosthesis and a plurality of openings that extend through the body from the anterior side to the posterior side thereof. At least a first and second opening of the openings are positioned at respective lateral and medial sides of a longitudinal axis of the tibial prosthesis. A modular insert is positioned within the recess of the body such that at least a portion of the modular insert is positioned between the openings of the body. The modular insert is formed separately from the tibial prosthesis and has a porous outer surface to promote tissue ingrowth.

An expandable implant device for implantation at a surgical site is provided. The implant device is made of cortical bone and includes a top and bottom piece, both pieces configured to couple with each other. The top piece has superior and inferior surfaces, and at least a tapered leading end configured to distract open an intervertebral disc space so that the top piece can be slidably inserted over the bottom piece until a desired overlap is achieved. A composite interbody bone implant device is also provided including a body skeleton having a non-bone composition, such as a polymer, formed into a shape and including one or more cavities which can be filled with other material, for example, allograft material. A method of placing an expandable device into a disc space is also provided.

A partial ankle prosthesis includes a tibial component including a superior surface configured to be attached to a lower end of a patient's tibia; a poly component that is fixedly attached to the tibial component and includes a concave inferior surface of an anti-friction material; and a talar component including an inferior surface configured to be attached to a patient's talus and a single convex superior surface configured to mate with the inferior surface of the poly component; and the partial ankle prosthesis is configured to be implanted in a single compartment of a patient's ankle.

Intervertebral implants for implanting into an intervertebral space are provided. The implants can comprise one or more layers that are operably attached to one another. An implant can comprise a first layer having a first mating surface that mates with a second mating surface of a second layer. The first mating surface and the second mating surface can have features that allow them to complement each other. The implants can include one or more bore holes for receiving a fixation member. The bore holes can be horizontal, vertical or diagonal. In some cases, the bore holes will be blind bore holes.

An apparatus and method is provided for interbody fusion including distracting, in a given direction, and supporting opposing vertebral bodies. A plurality of wafers are consecutively inserted between the vertebral bodies to create a column of wafers. The column of wafers is oriented between the vertebral bodies so as to expand in the given direction as the wafers are consecutively added to the column.

A shoulder implant system comprising a glenoid implant; a baseplate comprising an implant facing surface to face the glenoid implant; wherein the glenoid implant comprises at least one fixation element configured to engage with at least one fixation element of the baseplate; wherein the at least one fixation element of the glenoid implant comprises a center post having a distal end; wherein the at least one fixation element of the baseplate comprises a center post receptacle; wherein the baseplate comprises an outer periphery; wherein the implant facing surface of the baseplate comprises a channel which extends from the outer periphery of the baseplate to the center post receptacle of the baseplate; and wherein the channel is configured such that, during an assembly of the glenoid implant and the baseplate, the distal end of the post is movable in the channel from the outer periphery of the baseplate to the center post receptacle of the baseplate.
