Intervertebral fusion device comprising a superior component, an inferior component, and a core component. The superior component comprises first and second superior parts which are coupled to each other to allow the first and second superior parts to move apart to thereby increase a perimeter of the superior component top side. The inferior component comprises first and second inferior parts which are coupled to each other to allow the first and second inferior parts to move apart to thereby increase a perimeter of the inferior component bottom side. The core component is configured for insertion between the superior and inferior components whereby separation between the superior and inferior components is determined. The core component interengages with each of the superior and inferior components upon insertion. The superior and inferior components are unattached to each other before the core component is inserted between the superior and inferior components. As the core component is progressively inserted between the superior and inferior components, the core component: bears against the first and second superior parts to push the first and second superior parts progressively apart; and bears against the first and second inferior parts to push the first and second inferior parts progressively apart.

A pedicle insulator implant is designed to protect the nerves and surrounding tissue from injury by pedicle screws or other surgical devices and instruments. The implant is configured to shield a fixture, reduce nerve root irritation, and diminish loosening of the fixture, when the fixture is implanted into the void of a target site. The implant includes features for stabilizing and securing the implant within the void at the target site. For example, in one embodiment, the implant includes one or more ridges and one or more teeth sections that stabilize the implant against rotational and extractive forces that could disturb the implant.

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.

In various embodiments, an implant for interfacing with a bone structure includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue. In some embodiments, a method is provided that includes accessing an intersomatic space and inserting an implant into the intersomatic space. The implant includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue.

A joint implant adapted for use in joint surgeries. Among other things, the joint implant has an anterior cutting edge and a rotatable cutter supported by a rotatable shaft. When surgical parameters require, the shaft can be detached from the implant. The present implant can include a rotatable shaft that has a conduit and windows.

An expandable implant includes a base member including a top surface, a first end, and a second end, and defining a central cavity positioned between the first end and the second end; an adjustable member including a top surface and at least one control channel, wherein the adjustable member is adjustably coupled to the base member and movable between a first, collapsed position, and a second, expanded position; a control shaft rotatable received by the base member, wherein rotation of the control shaft cause relative movement of the adjustable member relative to the base member; and at least one control member received on the control shaft and by the control channel, wherein rotation of the control shaft causes the control member to translate along the control shaft and along the control channel.

A spinal facet fusion implant comprising: an elongated body having a distal end, a proximal end and a longitudinal axis extending between the distal end and the proximal end, the elongated body being characterized by a superior body surface and an inferior body surface; a superior stabilizer extending outwardly from the superior body surface, the superior stabilizer being characterized by a superior stabilizer surface; and an inferior stabilizer extending outwardly from the inferior body surface, the inferior stabilizer being characterized by an inferior stabilizer surface; wherein (i) the superior body surface and the inferior body surface are tapered relative to one another, and/or (ii) the superior stabilizer surface and the inferior stabilizer surface are tapered relative to one another.

A bone implant holding and shaping tray is provided. The tray includes a first segment having a distal end and a first surface sized to hold and shape at least a portion of the bone implant with bone material. The tray includes a second segment having a second surface sized to hold and shape at least a portion of the bone implant with bone material, the second segment having a proximal end configured to be coupled to the distal end of the first segment so as to extend the first surface to hold and shape the bone implant. Methods of making and using the bone implant holding and shaping tray are also provided.

A spinal bone graft includes one or more cortical bone portions forming a first unit. The first unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms at least one first undercut. The bone graft also includes one or more cortical bone portions forming a second unit. The second unit includes an engagement surface for contacting bone, and a mating surface. The mating surface forms either at least one second undercut, or at least one connector. In the former, at least one connector is received in each of the first and second undercuts to interconnect the first and second units. In the latter, the at least one connector of the second unit is received in the first undercut of the first unit to interconnect the first unit and second unit.
